GTA Online Diamond Casino Heist guide: An overview of the gameplay
Like many other heists and missions, The Diamond Casino Heist is also related to a property (Arcade business). That said, you must first trigger an event that will unlock the property before you can access the heist mission. You will work for Georgina Cheng and be guided by Lester Crest during this mission.
Once you unlock the heist, Lester will ask you to scope the resort and find various points of interest. After that, you will have to find out what is stored in the vault of the property by accessing the security camera feed. Upon completing these two steps, you will start engaging in the main gameplay of this heist.
Rockstar included the following items as loot targets for The Diamond Casino Heist:
- Cash — $2.1 million
- Art — $2.3 million
- Gold — $2.5 million
- Diamonds — $3.2 million
Readers should also note that there are three approaches to execute the mission:

How to unlock the Arcade business in GTA Online?
To unlock the Arcade business, you must first meet Lester and Georgina Cheng in Mirror Park. Look for a green L marker on the map and go there to trigger a long cutscene.

Once the cutscene is done, go to the Maze Bank Foreclosures website and do the following steps:
- Click on the Arcade button on the website to filter out all the Arcade locations.
- Select a location where you want to set up your business.
- Go through the customization options.
- Once done, click on the Buy button.

Understanding the scoping part of The Diamond Casino Heist in GTA Online
Scoping the entire Diamond Casino & Resort is very important, as it marks the various entry and exit points alongside other important areas of the building. You will have to visit the property physically and click pictures of various objects as per Lester's instructions.
While scoping out the main entrance, security guard, keypad, and security cameras are among the most important things, the GTA Online Diamond Casino Heist guide advises you to click photos of the following locations as well:
- Any of the security cameras inside the casino.
- The door at the main area of the terrace.
- The terrace entry door to the north side.
- The terrace entry door to the south side.
- The terrace entry door to the northeast side.
- Two roof entrance doors.
- Entrance doors at the side of The Diamond Casino.
- The waste disposal entrance doors towards the north side.
- Any old security cameras outside the Casino.
- The security entrance at the underpass near the casino.
- The sewer tunnel entrance.
- Blueprints of the vault in Agatha Baker’s desk.
By clicking photos of all the 16 points of interest, Lester will be able to help you better with the heist planning and execution.

Finding the vault content for The Diamond Casino Heist in GTA Online
Scoping the vault content mission is easy and short, but you will have to maintain a stealthy approach. First, you will have to find a security guard that Lester Crest tells you about. The guard always remains a few miles away from the Casino area. Once you find him, you will have to hack his phone using the SecuroServ app.
The GTA Online Diamond Casino Heist guide advises players to maintain a safe distance from the guard so that they don’t spook him. If you end up spooking him, you will have to kill the guard and steal his phone. Rockstar Games will also give you a two-star wanted level.
Once the hacking/stealing process is done, arrive at The Diamond Casino and open the Sightseer app on your phone. On the bottom right corner of your screen, you will see a signal strength bar appearing. Roam around the Casino premises with the Sightseer app opened to find the area with the strongest signal. Then, you will be able to access the security camera footage of the building.
If you are playing the heist for the first time, Rockstar Games will likely give you the cash reward only. Sometimes, if you are lucky, you can find art and gold bars as well. The diamond loot target is extremely rare and only appears on special occasions. Therefore, the GTA Online Diamond Casino Heist guide readers should move ahead with whatever they find inside the vault.
The security camera footage will be accessible for two minutes.

A brief overview of the Aggressive approach to the Diamond Casino Heist
As the name suggests, this approach will be the most violent one. In it, you will have to fight with the guards and all other enemies from the very beginning. There is no stealth and hiding in this mission, with you having to make your way through after killing all enemies.
The GTA Online Diamond Casino Heist guide advises you to do the following prep missions beforehand:
- Thermal Charges
- Vault Explosives
- Reinforced Armor
- Tunnel Boring Machine
You must also not forget to refill your ammo, snacks, and armor, as there will be a lot of gunfights. While the objective and approach sound simple on paper, you must prepare for a war with the aimbots.
The Diamond Casino Heist cannot be played solo. You must hire at least one more player to access the finale. On the final screen before the mission, you will be able to set the entry point, exit point, buyer, and how much cut your associate(s) gets. After stealing the loot from the Casino, you must deliver it to the designated buyer to complete the heist.
