How to do The Diamond Casino Heist in GTA Online

The Diamond Casino Heist is an incredibly lucrative GTA Online activity, but unlocking it can be a bit unintuitive. Most players in 2024 should already know that they must buy the Arcade business venture to access this heist. However, the property isn't available for purchase from the get-go. First, players must meet Lester Crest at the Mirror Park area in Los Santos.

Therefore, a simple step-by-step guide on how to do The Diamond Casino Heist could boil down to the following:

1. Meet Lester Crest at Mirror Park
2. Purchase an Arcade
3. Do the setup and preparation missions for the heist

The rest of this article covers these details in more depth, particularly for those who wish to host this heist in 2024.

When starting a game as a beginner, the players will receive a text from Lester Crest telling them to meet him at Mirror Park. Simply go to the "L" at Mirror Park and a cutscene will be initiated. You will see Georgina Cheng make her debut, and she will convince your in-game character and Lester to do The Diamond Casino Heist.

However, you are now tasked with purchasing an Arcade to use as a front for this big heist. Buying this property is mandatory if you wish to do The Diamond Casino Heist, so you cannot skip this step if you plan to host the entire thing.

Buying an Arcade in GTA Online

Go to floreclosures.maze-bank.com and look for any Arcade. Your options are:

• Blaine County, Paleto Bay: $1,235,000
• Blaine County, Grapeseed: $1,565,000
• East Los Santos, La Mesa: $1,875,000
• South Los Santos, Davis: $2,135,000
• North Los Santos, Vinewood: $2,530,000
• North Los Santos, Rockford Hills: $2,345,000

The one in East Los Santos is the closest to the casino, but any of these Arcades is fine to purchase. Once you buy any of them in GTA Online, you need to go to the property and visit its basement.

There, you will find Lester Crest planning the heist. He will task you with a setup mission to get the Arcade all set up. After that's done, you can do the setup and preparation missions for this heist.

Doing The Diamond Casino Heist

GTA Online players should be able to get started with this heist by now. Here are a few things to consider:

• You can begin everything by using the heist planning board in the basement of the Arcade
• The setup and preparation missions can be done solo
• The actual heist requires 2~4 people
• There are three different approaches for the finale
• You don't have to do every preparation mission
• Setup costs $25,000
• Different primary targets pay different amounts of money

Unless you do the Heist Replay Glitch, you will have to repeat the preparation missions whenever you wish to redo this job. Still, there is the potential to earn millions when completing The Diamond Casino Heist, especially if you play with friends you can trust rather than random.

The most confusing part about unlocking this heist in GTA Online is meeting Lester Crest and then buying the property since that sort of requirement isn't standard for other heists.

Even after a lot of activities available in the game in 2024, the Diamond Casino Heist is still one of the best ways to earn money.
