Planning and Preparation for the Diamond Casino Heist

Choose Your Crew Wisely

When planning the Diamond Casino Heist in GTA Online, it's important to choose your crew wisely. Each crew member brings unique skills to the table that can help you complete the heist more efficiently and without drawing too much attention. Look for crew members with high stats in areas like hacking, driving, and shooting.

Scope Out the Casino

Before committing to the heist, it's essential to scope out the Diamond Casino and Resort. This involves gathering intel on the casino's security measures, such as cameras, guards, and checkpoints. Find the location of the security room and hack into the system to disable cameras and unlock doors.

Plan the Approach

There are several ways to approach the Diamond Casino Heist, and it's important to choose the one that will work best for your crew's skillset. The two main approaches are the Aggressive and Silent & Sneaky approaches. The Big Con approach is also available, but it requires more prep work. Consider the pros and cons of each approach and make a plan before starting the heist.

Invest in Equipment and Vehicles

To complete the Diamond Casino Heist successfully, you'll need the right equipment and vehicles. This includes things like hacking devices, getaway cars, and weapons. Don't skimp on equipment, as it can mean the difference between a successful and failed heist. Keep in mind that investing in these items can be expensive, so make sure you have enough cash on hand before beginning the prep work.

Choosing Your Approach


If you prefer a more discreet approach, stealth might be the right choice for you. This approach requires players to avoid being detected by guards and security cameras while navigating the casino. It is important to have a team that communicates effectively and moves quietly to avoid detection. Stealth approach offers a higher payout but requires patience and precision.


For those who prefer a more action-packed approach, the aggressive strategy might be a better option. This approach involves using force to eliminate guards and security personnel. It's recommended to have good combat skills and heavy weapons to pull this off. The aggressive approach may attract more resistance but can be completed more quickly than the stealth approach.

Big Con

If you want to disguise yourselves as employees or guests of the casino, the big con might be suitable for you. This approach requires players to dress up and act as employees and trick their way through the casino's security system. The big con approach offers a mid-range payout and requires excellent improvisation skills and acting ability.

When choosing an approach, consider your skills, character costumes and team players. Each approach has its unique benefits, risks, and rewards. Pick the one that suits your playstyle and equipment the best and achieve a successful heist.

Scope Out the Casino

One of the most important steps in mastering the Diamond Casino Heist in GTA Online is to scope out the casino properly. This involves a careful reconnaissance of the entire casino, including its main entrance, the front desk, the staff area, various access points, and the vault location.

Make sure to bring a camera and take plenty of photos, as these will be helpful during the planning phase of the heist. You should also look for security cameras and guards, and note their patrol patterns and behavior. This will allow you to plan your entry and exit routes carefully, avoiding detection and maximizing your chances of success.

Keep in mind that the casino is a highly secure facility, with state-of-the-art security systems and well-trained guards. You will need to find creative ways to bypass these defenses and avoid detection, such as disguises, distractions, and hacking tools.

During the scope out phase, you should also be on the lookout for potential entry and exit points, such as side doors, windows, or ventilation shafts. These can provide useful shortcuts and escape routes, but may also require special equipment or tools to access.

Finally, don't forget to pay attention to the casino's layout and design, as this can provide valuable clues and insights into its security measures and weak points. With careful preparation and planning, you can increase your chances of pulling off the ultimate heist and walking away with a massive payout.

Deciding on Your Crew

Choosing the Right Team Members

When planning the Diamond Casino Heist in GTA Online, one of the most important decisions you will make is selecting your crew. Choosing the right team members can make the heist run smoothly and increase your chances of success.


When selecting your crew, there are several factors to consider. First, each crew member has unique skills that can be valuable during the heist. You’ll want to choose team members whose skills complement each other. Additionally, you’ll want to consider their cut percentage, which can vary based on their skill level and availability.

Roles and Skills

There are three main roles in the Diamond Casino Heist: hacker, driver, and gunman. Each role requires different skills and tools, so it’s important to choose your crew members accordingly.

The hacker will be in charge of bypassing security systems and disabling alarms. A skilled hacker can make the heist go much smoother. The driver will be responsible for getting the team to and from the casino quickly and safely. A skilled driver with a fast car can help you evade the police and make a clean getaway. The gunman will be in charge of taking out security guards and other obstacles in your way. A skilled gunman with powerful weapons can help you make it through the heist with minimal casualties.

Communication and Coordination

Once you’ve chosen your team members, it’s important to communicate and coordinate with them effectively. Make sure everyone knows their role and what they need to do during the heist. Plan out your approach and make sure everyone is on the same page.


Choosing the right crew members and planning your approach carefully can make all the difference in the Diamond Casino Heist. Consider each crew member’s skills and cut percentage, choose roles that complement each other, and communicate effectively to ensure a successful heist.

Building Your Setup

Choosing Your Approach

One of the first steps in building your setup for the Diamond Casino Heist is choosing your approach. There are three different approaches: silent and sneaky, the Big Con, and aggressive. Each approach requires different prep work and outfits, so it’s important to choose the one that suits your playstyle and skill level.

Gathering Your Crew

Once you’ve chosen your approach, it’s time to gather your crew. You’ll need to recruit at least one gunman, one driver, and one hacker. Each member will have different abilities and gear that will be useful during the heist. Make sure to choose team members that complement your approach and have the necessary skills.

Prepping Your Gear

Next, it’s time to prep your gear. This includes everything from weapons and vehicles to outfits and equipment. As you progress through the prep missions, you’ll unlock access to better gear and upgrades, so it’s worth taking the time to complete all of the prep work.

Scouting Out the Casino

Before the heist, it’s important to scout out the casino. This will allow you to familiarize yourself with the layout and identify potential security measures. It’s also a good opportunity to gather intel on the vault contents and access points.

Managing Your Finances

Finally, it’s important to manage your finances. The Diamond Casino Heist requires a significant investment in equipment and crew members, so you’ll need to make sure you have enough money to cover all the costs. You can boost your profits by completing optional objectives during the heist, so keep an eye out for opportunities to earn extra cash.

Executing the Heist

Choose your approach

There are three ways to approach the Diamond Casino Heist: The Aggressive approach, The Silent and Sneaky approach, and The Big Con. You'll need to pick the approach that best suits your playstyle and skill level. Each approach has its own benefits and drawbacks, so make sure to weigh your options before making a decision.

  • The Aggressive approach is the most difficult, but it offers the highest potential payout.
  • The Silent and Sneaky approach requires the most precision and coordination, but it's also the most stealthy.
  • The Big Con is the easiest approach, as it involves disguising yourself as casino employees, but it also requires good acting skills.

Prepare for the heist

Before you attempt the heist, you'll need to make sure you've done all the necessary preparation. This includes choosing your crew, sourcing getaway vehicles, and completing any necessary setup missions.

Make sure to choose crew members with the right skills and equipment for your chosen approach. You'll also need to decide on your getaway vehicles and make any necessary upgrades to ensure a smooth escape.

Execute the heist

When it's time to execute the heist, make sure to coordinate with your crew and communicate effectively. Use the hacks and devices you acquired during the preparation phase to bypass security systems and gain access to the target.

Be prepared to adapt to unexpected situations and be ready to engage in combat if necessary. Once you have the loot, make sure to escape quickly and efficiently to ensure a successful heist.

Dealing with Security

Disabling Security Measures

One of the most important things you need to do before starting the Diamond Casino Heist is to disable the security measures. The first thing you need to do is to hack into the security cameras and use the security feed to locate the guards and other security personnel. Once you have located them, you can take them out quietly without raising any alarms. You can also disable the metal detectors and cameras using special equipment. Make sure you do this carefully and quietly to avoid alerting the guards.

Avoiding Security Cameras

The Diamond Casino is loaded with security cameras, and you need to be careful and avoid them at all costs. When you are moving around the casino, try to stay out of the cameras' line of sight. If you can't avoid the cameras, you can use special equipment to partially jam the cameras or use the EMP to temporarily disable them. Remember, the longer you stay in the camera's view, the higher the chances of getting spotted by the guards.

Dealing with the Guards

The guards in the Diamond Casino are heavily armed and trained to handle any situation. One strategy for dealing with them is to take them out quietly using melee attacks or silenced weapons. Another strategy is to use distractions to lure them away from their posts, making it easier for you to sneak past them. You can also use the stun gun to incapacitate them temporarily. Be careful not to let any guards or security personnel see you, as this will raise the alarm and trigger a shutdown of the casino.

Getting Through the Doors

The Diamond Casino has several locked doors that you need to get through to reach your objectives. To do this, you need to hack the keypads using your hacking device. The keypads have a series of numbers that you need to enter in the correct sequence. If you enter the wrong sequence, the alarm will be triggered, and the guards will be alerted. Take your time and be patient when hacking the keypads. If you get stuck, you can use the fingerprint scanner to bypass the keypad.

Avoiding Detection: Tips and Tricks for the Diamond Casino Heist

Stay Away from Restricted Areas

One of the most important ways to avoid detection during the Diamond Casino Heist is to steer clear of restricted areas. Pay attention to the security cameras and avoid walking in front of them unless absolutely necessary. Also, avoid entering areas that are marked with "No Trespassing" signs or areas that are off-limits to casino guests. If you do need to enter a restricted area, make sure to use appropriate disguises or hacking tools to bypass security measures.

Be Mindful of Your Outfit

What you wear during the Diamond Casino Heist can also play a key role in avoiding detection. Consider wearing inconspicuous clothing, such as a suit and tie, which can blend in with other casino guests. Avoid clothing that is too bright or flashy, which can make you stand out and attract the attention of security guards. It's also a good idea to change outfits frequently to avoid raising suspicion.

Take Advantage of Your Surroundings

Another way to stay undetected during the Diamond Casino Heist is to take advantage of your surroundings. Use cover, such as plants and furniture, to hide behind or crouch down when necessary. Use the environment to your advantage, and try to stay out of sight of security guards. If you do need to move quickly, use the cover of darkness or other distractions, such as loud noises or alarms, to mask your movements.

Work as a Team

Finally, one of the most important things you can do to avoid detection during the Diamond Casino Heist is to work as a team. Communicate with your co-conspirators and develop a plan for avoiding detection. Assign roles and responsibilities to each member of the team to ensure everything runs smoothly. Remember, the Diamond Casino Heist is a complex operation, and everyone needs to work together to ensure success.

Hacking Doors and Safes: An Essential Skill for Mastering the Diamond Casino Heist

If you're looking to pull off a successful heist at the Diamond Casino, one skill you absolutely need to master is hacking doors and safes. This means understanding the basics of hacking in GTA Online and knowing how to bypass security systems.

One of the best ways to hack doors and safes in the Diamond Casino Heist is to use the hacking device. This is an electronic tool that allows you to bypass electronic locks and hack into security systems. You can find this device in your inventory or purchase it from an equipment vendor. It's important to remember that the hacking device can only be used when you have a direct line of sight to the device or door you want to hack.

Another option for hacking doors and safes is to use the drill. This tool allows you to break through physical barriers like doors or safes. While this option can be louder and attract more attention, it's often faster than using the hacking device. Just make sure to bring enough drills to handle any doors or safes you encounter during the heist.

When hacking doors and safes, it's important to pay attention to the hacking mini-game that appears on your screen. This mini-game requires you to match codes or solve a puzzle to bypass the security system. Make sure to use your hacking device or drill in a safe location where you can focus on the mini-game without being detected by security guards or cameras.

In conclusion, hacking doors and safes is a critical skill for mastering the Diamond Casino Heist. Make sure to bring the right tools and pay attention to the mini-game to successfully bypass security systems. With these tips and tricks, you'll be well on your way to pulling off the perfect heist.

Using Drills and Explosives

The Importance of Drills and Explosives in the Diamond Casino Heist

Drills and explosives are essential tools for any crew looking to pull off a successful Diamond Casino heist. These tools are used to gain access to safes, vaults, and other secure areas within the casino. Without them, the crew would be limited in their ability to rob the casino of its most valuable items.

Types of Drills

There are two main types of drills used in the heist: the standard drill and the thermal drill. The standard drill is used to crack locks on doors, cabinets, and other mechanical security features. The thermal drill, on the other hand, is used to gain access to reinforced safes and vaults, as it can melt through metal with ease.

Using Explosives

Explosives are another important tool in the heist, but they must be used with caution. Explosives can be used to blow open the doors of safes and vaults, but they can also attract unwanted attention from the authorities. It is important for the crew to carefully plan and execute the use of explosives to avoid getting caught.

  • Use explosives sparingly to avoid alerting guards
  • Use silenced weapons to cover up the sound of explosions
  • Make sure to have an escape plan in place in case of emergency


Drills and explosives are vital tools in the Diamond Casino heist and can greatly increase the crew's chances of success. However, it is important for the crew to use these tools with caution and only when necessary, in order to avoid drawing unwanted attention from the authorities. With the right planning and execution, the use of drills and explosives can lead to a big payoff for the crew.

Operating the Thermal Drill Tips

The Thermal Drill is an essential tool you need to achieve success in the Diamond Casino Heist. It is a noisy and attention-grabbing tool, so it is essential to operate it correctly while being cautious not to alert the guards.

Where to find the Thermal Drill?

You can find the Thermal Drill in two places in the game. The first location is in the casino's basement, while the second location is in the roof terrace. Ensure you check both locations to find the drill.

How to use the Thermal Drill?

To use the Thermal Drill, equip it by pressing "Q" or the relevant key on your console. After that, take it to the vault and get started on the drilling process. But be cautious, as the drill can overheat and break if not handled correctly. Also, ensure that no guards are around, as its loud noise can alert them to your location.

How to prevent the drill from overheating?

The Thermal Drill has a heat gauge that builds up as you use it. To prevent overheating, be cautious not to use the drill continuously. Instead, use it in short bursts and wait for it to cool down before starting again. Alternatively, you can upgrade the drill using the "Drill Upgrade" in the "Buy Assets" column to reduce its heat build-up.

  • Equip the drill by pressing "Q".
  • Ensure no guards are around to avoid being detected.
  • Use the drill in short bursts to prevent overheating.
  • Upgrade the drill to reduce the heat build-up.

Finding the Safe Contents in the Diamond Casino Heist

Scoping the Casino

Before starting the Diamond Casino Heist, it is important to scope the casino thoroughly to locate different entry points and exit routes. While scoping, keep an eye out for security cameras and guards, as their presence can hinder the successful completion of the heist. In particular, look for a door leading towards the security area to disable the metal detectors.

Cracking the Safe

Once inside the casino, players must locate the vault and start cracking the safe. The safe requires player-class specific tools to crack, including drills and explosives. Additionally, ensure that the hacking skill is upgraded to facilitate cracking the safe quickly. Be mindful of the timer, as any delay can result in detection by guards, which can lead to the failure of the heist.

Finding the Contents

Once the safe is cracked, players can access the cash and diamonds hidden inside. It is important to collect all the valuable contents swiftly and efficiently, as alarms can attract the attention of guards and thereby increase the risk of getting caught. Additionally, players must be careful to avoid any booby traps that may be placed inside the safe.


In conclusion, finding the safe contents is a crucial part of the Diamond Casino Heist. Players must be cautious and attentive throughout the scoping and cracking process and must act rapidly to collect all the valuable items while avoiding detection from guards. Mastery of these techniques can help ensure the heist's success and maximum payout.

Evading the Cops

Stay Calm and Move Strategically

When evading the cops during the Diamond Casino Heist, it's important to stay calm and move strategically. Don't panic and start running in random directions. Instead, stay focused and move purposefully towards your escape vehicle. Stay out of the cops' line of sight and use cover to your advantage.

Plan Your Escape Route

Before the heist even begins, it's a good idea to plan out your escape route. This includes identifying potential obstacles and finding alternative routes. During the actual heist, stick to the planned escape route as closely as possible. Avoid making sudden or unplanned detours, as this will increase the risk of getting caught.

Use Diversion Tactics

If the cops are hot on your tail, consider using diversion tactics to throw them off your scent. This can include creating distractions, such as setting off explosions or causing a traffic jam. Another tactic is to split up and go in different directions, which can confuse the cops and give you a better chance of getting away.

Utilize the Environment

The environment around the Diamond Casino can help or hinder your escape. Take advantage of alleys, tunnels, or other hidden pathways to move around undetected. On the other hand, avoid open areas such as streets or parking lots, which can make you an easy target for the cops.

Communicate with Your Team

Effective communication with your team is vital when evading the cops. Make sure everyone knows the planned escape route and any backup plans. Call out any obstacles or potential threats, and work together to overcome them. Remember to stay calm and focused, and work together as a team to make a clean getaway.

Maximizing Your Diamond Casino Heist Loot

Obtaining the Maximum Payout

  • Make sure you have the best possible team for the job, including a capable hacker, driver, and gunman.
  • Choose the right approach - some may yield a higher payout than others.
  • Scout the casino and plan your route carefully, taking note of security measures and guards' movements.
  • Consider using disguises or other tactics to avoid suspicion and detection.
  • Access the vault quietly and quickly - the longer you take, the more likely you are to get caught.
  • Choose your loot wisely - some items are worth more than others.
  • Use your hacker to disable security measures and open more doors to access additional loot.
  • Have your getaway vehicle prepped and ready to go, with a skilled driver to make a clean escape.
  • Be aware of potential complications, such as alarms or security reinforcements, and have a contingency plan in place.
  • Take advantage of any bonuses or multipliers available to increase your payout.

With careful planning, a skilled team, and a bit of luck, you can walk away from the Diamond Casino Heist with a huge haul of cash and valuables. So gather your crew and get ready to execute the perfect heist!

Tips for Solo Players in Mastering the Diamond Casino Heist

1. Plan your approach carefully

As a solo player, it's crucial to plan your approach carefully before starting the heist. Make sure to choose the right crew members with the right skills and equipment, and select the best entry and exit points. Use the intel gathered during the planning phase to identify security cameras, guards, and other obstacles.

Pro tip: Consider using the sewers as an entry and exit point. They are usually unguarded and can provide a quick and safe escape route.

2. Invest in the right equipment

Invest in the right equipment to make your heist easier and more efficient. Purchase suppressed weapons to take out guards without raising the alarm, and use hacking devices and lockpicks to bypass security systems and open locked doors.

Pro tip: Use the nano drone to scout ahead and identify any potential threats and obstacles.

3. Use cover and move stealthily

As a solo player, you have to rely on stealth to complete the heist successfully. Use cover to avoid detection and move slowly and quietly to avoid detection by guards and cameras. Take out guards silently if necessary, but avoid unnecessary confrontation.

Pro tip: Use the suppressor attachment on your weapon to take out guards without alerting others.

4. Take advantage of shortcuts and hacks

There are many shortcuts and hacks you can use during the heist that can save you time and make your job easier. For example, use the security intel to disable specific cameras and alarms, or use the maintenance tunnels to bypass security measures.

Pro tip: Use the EMP to temporarily disable all electronic devices in your vicinity, including cameras and alarms.

5. Be prepared for unexpected events

As a solo player, you have to be prepared for unexpected events, such as alarms, guards, or other players interfering with your heist. Stay calm and adapt your strategy to the situation. Don't be afraid to abort the mission if things get too difficult.

Pro tip: Use the smoke grenade to create cover and confusion, or use the thermal charges to quickly access locked doors and safes.

Tips for Playing with a Crew

Playing with a crew can make the Diamond Casino Heist much easier and more enjoyable, but it also requires some coordination and communication. Follow these tips to maximize your success:

  • Communicate: Set up a voice chat or use in-game communication tools to discuss your strategies and goals before and during the heist. Make sure everyone knows their role and responsibilities, and keep each other updated on any changes or issues that arise.
  • Choose complementary roles: Each player should pick a role that complements the others. Consider dividing responsibilities such as hacking, crowd control, and driving the getaway vehicle among different players to ensure everyone has a role to play.
  • Be patient: The heist can be long and challenging, especially if you're aiming for maximum payout. Keep a cool head and remind your crew to stay focused and patient, even if things don't go according to plan.
  • Watch each other's backs: Keep each other safe from enemies and police officers, and help each other out when needed. Don't hesitate to revive a fallen teammate or provide cover for someone who needs to complete an objective.
  • Be flexible: Don't be afraid to change your plans if something unexpected happens. Adapt to the situation and consider alternative solutions if your original plan falls through.
  • Share the rewards: Split the payout fairly among the crew members, and consider redistributing the shares if someone contributed more than others. This will make everyone feel appreciated and encourage them to play together again in the future.
