🏁 Step 1: Meet the Requirements
Diamond Casino Heist : Before unlocking The Big Con, ensure you’ve met the prerequisites:
- Buy an Arcade: Visit Maze Bank Foreclosures. Buy an arcade property (e.g., Pixel Pete’s in Paleto Bay or one in the city like Videogeddon).
- Complete the Setup Mission: After buying the arcade, Lester will contact you. Complete the Arcade Setup mission to unlock the heist planning board.

🔓 Step 2: How to Unlock the Big Con
Diamond Casino Heist : To unlock The Big Con, follow these steps:
- Go to the Planning Board: Inside your arcade, access the heist planning board.

💡 Tip: You can cancel and restart the heist setup to refresh the available approaches if The Big Con is not offered initially.
