Quick Answer
To start the Diamond Casino Heist in GTA Online, you must first own a high-end apartment (e.g., Eclipse Towers, Del Perro Heights) or a CEO office with a vehicle warehouse. Then, purchase an Arcade property from the Maze Bank Foreclosures website via your in-game phone. Once you own an Arcade, visit the planning board inside to begin the heist setup. The heist is launched by Lester Crest, who will contact you after you buy the Arcade. Note: This is purely a fictional in-game activity in Grand Theft Auto V Online, a video game rated R18+ in Australia. It does not involve real gambling, real money, or real casinos, and is not subject to the Interactive Gambling Act 1997 (IGA).
Step-by-Step Guide to Unlock and Start the Diamond Casino Heist
1. Meet the Prerequisites
Before you can start the heist, ensure your GTA Online character meets these requirements:
- Rank: You must be at least Rank 1 (no minimum rank is required, but having a high-end apartment or CEO office is necessary).
- Property: Own a high-end apartment (e.g., Eclipse Towers, Apt 3; Del Perro Heights, Apt 20; or Tinsel Towers). Alternatively, own a CEO office with a vehicle warehouse (requires the “Executive” update).
- Phone Contact: Lester Crest must be available in your contacts. If not, complete the “The Fleeca Job” (first heist) to unlock him.
2. Purchase an Arcade Property
The Arcade is the central hub for the Diamond Casino Heist. Here’s how to buy one:
- Open your in-game phone (press ‘M’ on PC, or the D-pad on consoles).
- Navigate to the internet browser (globe icon) and go to the “Maze Bank Foreclosures” website.
- Scroll down to “Arcades” – there are eight locations across Los Santos (e.g., Pixel Pete’s in Paleto Bay, Videogeddon in La Mesa). Prices range from $1,235,000 to $2,530,000 in GTA dollars.
- Select a location, confirm payment, and the Arcade becomes yours. You can also upgrade it later (e.g., add a drone station, security room) for additional costs.
3. Receive the Call from Lester
After purchasing the Arcade, Lester Crest will call you, introducing the Diamond Casino Heist. This call triggers the initial setup. If you miss the call, check your phone’s contacts and call Lester directly – he will guide you to the next step.
4. Visit the Arcade and Use the Planning Board
Travel to your Arcade property. Inside, locate the planning board (a large screen or whiteboard in the main room). Interact with it to:
- Choose a Heist Approach: You can select from three approaches: The Big Con (disguise), Silent & Sneaky (stealth), or Aggressive (direct assault). Each has different setup missions and rewards.
- Select a Crew: Hire optional crew members (e.g., gunman, driver, hacker) from the board. Better crews cost more but improve success rates.
- Start Setup Missions: The board will display a list of required setup missions (e.g., scope out the casino, acquire equipment, prep vehicles). You must complete these missions to unlock the final heist.
5. Complete Setup Missions
Setup missions are instanced tasks that can be done solo or with friends. Examples include:
- Scope Out the Casino: Take photos of security cameras, vault doors, and guard posts using your in-game phone.
- Get Keycards: Steal keycards from security guards at locations across the map.
- Acquire Equipment: Steal drills, explosives, or hacking devices from various NPCs.
Each setup mission has a preparation cost (in GTA dollars) and may require you to source vehicles (e.g., getaway cars, armored trucks).
6. Launch the Final Heist
Once all setup missions are complete, Lester will notify you that the heist is ready. Return to your Arcade’s planning board and select “Start Heist.” You need at least one other player (up to three) to join your crew. The heist plays out in real-time, with objectives like hacking vault doors, avoiding guards, and escaping with the loot.
Important Gameplay Tips
- Practice Hacking: The heist includes mini-games (e.g., fingerprint scanning, keypad code cracking). Practice in the Arcade’s arcade machines or during setup missions.
- Use the Arcade Upgrades: Purchase the “Drone Station” or “Security Room” upgrade to make setup missions easier (e.g., drones can scout ahead).
- Manage Heat: After the heist, avoid being killed by police or NPCs – failure reduces your payout.
- Daily Cooldown: The heist has a 48-minute real-time cooldown after completion before you can start another.
Australian Laws and GTA Online: What You Need to Know
The Diamond Casino Heist is a fictional, scripted activity within Grand Theft Auto V Online, a video game rated R18+ by the Australian Classification Board. It is not real gambling, real money gambling, or a simulated casino game that violates the Interactive Gambling Act 1997 (IGA). The IGA regulates real-money online gambling services (e.g., online slots, sports betting) offered to Australian residents by operators. Since GTA Online uses only in-game currency (GTA dollars) that cannot be converted to real money, and the heist involves no real stakes, it is exempt from Australian gambling laws.
However, Australian players should be aware of the following:
- No Real Money Gambling: The Diamond Casino in GTA Online (a separate feature from the heist) includes virtual slot machines and table games that use GTA dollars. While these are not real gambling, they are designed to mimic casino mechanics and may be problematic for individuals with gambling tendencies. The IGA does not cover this, but the Australian eSafety Commissioner advises caution with “loot boxes” and simulated gambling in games.
- In-Game Purchases: GTA Online offers “Shark Cards” (purchasable with real money) to buy GTA dollars. This is a microtransaction system, not gambling, but it can create a “pay-to-win” dynamic. The Australian Competition and Consumer Commission (ACCC) monitors such practices for fairness.
- Age Restrictions: GTA V is R18+ in Australia, meaning it is legally restricted to adults. Players under 18 should not access the game, and parents should enforce this.
Key Takeaways for Australian Players
- The Diamond Casino Heist is an in-game activity in GTA Online that requires an Arcade property, setup missions, and a crew to complete. It is purely fictional and uses no real money.
- Australian gambling laws (IGA 1997) do not apply to this feature because it involves no real-money gambling or prize conversion. However, the game includes simulated casino elements that may be regulated under broader consumer protection laws.
- Always play responsibly. If you or someone you know experiences gambling harm, contact Gambling Help Online (1800 858 858) or Lifeline (13 11 14).
- Never use real-money third-party services to buy GTA dollars or “boost” heist progress – such activities are against Rockstar Games’ terms of service and may be illegal under Australian law.
