Video game guide: This article is about GTA Online, a video game. Everything below happens inside the game — the chips, cash, prizes and vault contents described exist only in-game and have no real-world value.
In GTA Online, The Diamond Casino Heist is a video game heist that starts from an Arcade and revolves around scoping the casino, identifying the vault contents, and choosing an approach for the finale. If you searched for how to get diamond casino heist or how to get diamonds for Diamond Casino Heist, the key point is that the supported steps cover how to unlock and check the vault contents, but they do not state a guaranteed method to force a specific vault target.
What you need first
Before you can start The Diamond Casino Heist, you must be active as the leader of a qualifying organization. The heist may only be played while active in a CEO or VIP Organization or in a Motorcycle Club, as the CEO, VIP, or MC President.
You also need an Arcade that has been set up. The host must own an Arcade that has been set up in order to start The Diamond Casino Heist, and the first time you set up the heist is free of charge, while each recurring time costs $25,000.
The finale itself supports a minimum of two players and a maximum of four. Each crew member has a minimum cut of 15% of the heist's earnings during the Finale.
| Requirement | What the game requires |
|---|---|
| Organization status | Be active in a CEO or VIP Organization, or in a Motorcycle Club, as the leader |
| Property | Own an Arcade that has been set up |
| Setup cost | First setup is free of charge; recurring setups cost $25,000 |
| Finale player count | Minimum of two players, maximum of four |
| Crew cut floor | Each crew member has a minimum cut of 15% |
How to unlock the Diamond Casino Heist
To begin heist planning, you first complete a setup mission from the Arcade property. Once that setup is done, the Arcade becomes operational and you can begin The Diamond Casino Heist.
From there, the first stage is handled on the Setup Board. This stage is where you scope out the casino and then scope out the vault contents.
- Become the CEO, VIP, or MC President of an eligible organization.
- Own an Arcade and complete its setup mission.
- Go to the Arcade planning area and open the Setup Board.
- Start the casino scoping task.
- After that, start the vault contents task to identify what is inside the vault.
- Once the vault contents are discovered, choose one of the three heist approaches.
How to scope the casino and vault contents
The first scoping task is the casino itself. You need to take pictures of security features and send them to Lester.
The minimum features are a security guard, door keypad, and security camera. After that, you can keep scoping until you discover a total of 6 access points, or you can leave the area and quit. This mission can be replayed later to find undiscovered features or access points.
The second scoping task is the vault contents. You go to the casino and hack into the security camera feed using the Sightseer app. Once the vault contents are found, you can continue browsing the security cameras to discover up to 10 additional points of interest.
- Start the casino scoping mission from the Setup Board.
- Photograph the minimum security features: a security guard, a door keypad, and a security camera.
- Optionally continue until you have discovered a total of 6 access points.
- Replay the mission later if you still have undiscovered features or access points.
- Start the vault contents mission.
- Go to the casino and hack the security camera feed with the Sightseer app.
- Identify the vault contents.
- Optionally keep browsing cameras to discover up to 10 additional points of interest.
Can you get diamonds in the Diamond Casino Heist?
If your question is how to get casino heist diamonds or how to get diamonds for Diamond Casino Heist, the supported information here is limited. The game does have a vault contents step, and you only learn what is in the vault by completing that scoping task.
What the current supported details do not establish is a specific method to make the vault contents come up as diamonds, a list of all possible vault targets, or any fixed condition that guarantees diamonds. So the honest answer is: you can discover the vault contents during setup, but this guide cannot confirm a documented way to force diamonds.
If you need the current event-specific availability of diamonds, check the in-game planning board and the community wiki page for The Diamond Casino Heist, because update-dependent content can change.
Approaches, prep work, and support crew
After discovering the vault contents, you can choose one of three approaches: Silent & Sneaky, The Big Con, or Aggressive. The facts support those approach names, but they do not give a full step list for each route here, so it is best to confirm the current prep board details in-game before you launch the finale.
Preparations are Freemode jobs that can be completed at any time. They help you gather the equipment for your chosen approach, from standard equipment to getaway vehicles.
These jobs can be done in public or private Freemode sessions, and they can also be performed in Invite Only, Friend, or Crew sessions. Each job can be completed by the CEO, VIP, or MC President alone, though that is not recommended.
Support crew members matter because they have different choices and percentage cuts at the end of the heist. Higher cuts usually mean better effectiveness.
| Heist element | Supported detail |
|---|---|
| Approaches | Silent & Sneaky, The Big Con, Aggressive |
| Prep structure | Prep Jobs are required to progress to the Finale |
| Where preps happen | Freemode, including public or private sessions |
| Private-session options | Invite Only, Friend, and Crew sessions are supported |
| Support crew | Different choices and percentage cuts; higher cuts usually mean better effectiveness |
Useful optional setup tools in the Arcade
On the Setup Board, you can optionally purchase three extras to practice for the finale in the Arcade. These are the casino model, door security, and vault door.
The vault door has one extra condition. It is only available if you discovered the vault blueprints on Ms. Baker's desk when scoping the casino.
These extras are presented as practice tools for the finale. The supported details do not list prices for them here, so check the in-game board for the exact current cost.
