Here I will explain what are the most important steps in preparing the Diamond-Casino-Heist and the heist itself. 1.)

Before you can start The Diamond Casino Heist in GTA Online, you need to purchase one of the six possible retro arcades in the game. You must talk to Lester in Mirror Park to access the arcades.

After you talk to Lester and the six arcade locations appear on the map, you can use the Maze Bank Foreclosures store webpage on your mobile phone to purchase one of the arcade locations.

Here are all the locations and their prices. The best arcades are located in the city.

  • Pixel Pete’s
    • Price: $1,235,000
    • Location: Paleto Bay
  • Wonderama
    • Price: $1,565,000
    • Location: Grapeseed
  • Videogeddon
    • Price: $1,875,000
    • Location: La Mesa
  • Warehouse
    • Price: $2,135,000
    • Location: Davis
  • Insert Coin
    • Price: $2,345,000
    • Location: Rockford Hills
  • Eight Bit
    • Price: $2,530,000
    • Location: Vinewood

Step 2: Set Up Your Heist

Once you have your arcade location up and running, you can enter Lester's underground base, where you will gain access to three blackboards. Use these blackboards to manage your heist.

The three blackboards represent the three following stages of the heist:

  • The Set Up
  • The Prep
  • The Heist

The first blackboard is dedicated to helping you set up your heist. You will see the 'To Do' list in the upper right corner, which is a list of actions you must perform before the actual heist.

You can also choose to do the optional list of tasks, but you will have to pay for all of the intelligence associated with them, so we'll just focus on the main missions.

Scope Out Casino

This is the first task you need to complete. To make things easier, it is advisable to purchase the two extras from the setup board:

  • Casino Model
    • Price: $130,000
  • Door Security
    • Price: $425,000

These two pieces of intelligence will help you to find all of the safest entry points into the casino.

Scope Out Vault Contents

After you arrive at the casino and find the vault, you can scope it out for four types of valuables:

  • Cash
    • Price: $2,115,000
  • Artwork
    • Price: $2,350,000
  • Gold
    • Price: $2,585,000
  • Diamonds
    • Price: $3,290,000

You can only choose one of the four options, and they are random. The best loot you can get from the vault is diamonds, which cost over $3 million. The least profitable is cash. So if you happen to get the case with diamonds, then select it and mark it on your blackboard.

Select Approach

The final part of the setup is selecting one of the three available approaches:

  • Silent and Sneaky
  • The Big Con
  • Aggressive

All three approaches offer different types of gameplay. Silent and Sneaky is obviously a stealth plan; The Big Con uses tricks and disguises; and Aggressive offers a full-on guns blazing robbery.

It doesn't matter which approach you choose, as they all lead to the same results. Choose the style that fits your personal taste the most.

Step 3: Prep Your Heist

This stage of the heist requires the most time and money. This stage is where you hire your crew of NPCs, select disguises, vehicles, and other necessary items from the 'To Do' list.

Support Crew

Heist

In this first section, you can choose three possible crewmen for the heist:

  • Gunman
  • Driver
  • Hacker

All three categories offer different skills, but these also come with varying prices. Whenever you choose a crewman, it will show you their cut in percentages. Obviously, the higher the skill, the higher the cut.

In this case, it is strongly recommended that you take all three Expert level crewmen, where each will take 9% of your heist earnings. It's a lot of money to give away, but you will have the highest quality weapons and vehicles during the heist.

The To-Do List

After you have chosen your team, you can start the six main prep missions. In each of these missions, you need to select which item types you wish to steal.

Below you will find the best choices for the prep missions:

  • Rifle Loadout
    • Unmarked Weapons
  • Sultan Classic
    • Getaway Vehicles
  • Gruppe Sechs
    • Entry Disguise
  • Noose Gear
    • Exit Disguise

During the Getaway Vehicles mission, you will also have the choice to upgrade your vehicles. You can buy bulletproof tires for $25,000, which will make the getaway section easier.

Step 4: Start the Diamond Casino Heist

You will be offered a chance to choose your buyer and get some extra help on the third blackboard.

Choose Buyer

Buyers have three levels: low, middle, and high. Always go for the high-level buyer. They will offer the most amount of money. The heist will be more difficult, but if you've done your prep correctly, and spent cash on the right things, then you should be fine.

Also buy a Clean Vehicle and Gunman Decoy for $50,000 if you can.

Starting the Mission

If you've selected the Gruppe Sechs entrance disguise and The Big Con approach, then you will start the heist mission in an armored truck, which is the best for this mission.

Here's how to get through the entire heist easily:

  1. Enter the underground garage of the casino
  2. Take the elevator to the vault
  3. Run past all the guards without killing them
  4. Use the vault keycard
  5. Let the casino worker open the vault for you
  6. Get the loot
  7. Exit the vault floor through the staircase
  8. Change the disguise in the locker room (Noose)
  9. Exit the casino through the staff door

When you're outside the casino, you can safely deliver the vault contents to your buyer.

Finish the Mission

The only problem you might run into during this final stage of the heist is the chasing helicopter. Steal any car you see and use it to deliver the loot (if you didn't purchase the Clean Vehicle option ahead of time).

If cops start chasing you, use the underground sewer system to get away from them and stay undetected. Follow the marker on the map to your buyer's location.

When you've reached the buyer location, the mission ends with a cutscene, and you get your money reward.

Vault content

Casino Heist Board

How can I cancel the heist and change the vault content ?

Once the three approaches are completed, you will be able to unlock the ability to call Lester and cancel the heist (you will lose the $ 25,000 in initial costs). After cancelling the heist you'll be able to restart the mission to scope the vault content.

The gold and the artwork.

You only need two players to collect all the artwork (using Paige or Avi as your hacker). Each item takes only 20 seconds to be collected.

You need 25 seconds to clear each cart containing gold. To collect all the gold carts you'll need at least 3 players. Using only 2 players will allow you to collect 7 out of the 8 carts.

During the heist you can also grab some extra cash from the secret vault, which is on the ground floor right next to the elevator.

The switch to open up the secret vault door is in the CCTV room next to the elevator.

You can expect somewhere between $20,000 to $100,000 to be in there. It will vary from heist to heist though.

The Gruppe Sechs gear. You will get direct access to the vault.

Increased security, and doors harder to hack

The amount to loot will also be increased.

Here are the optionnal prep missions we recommend you do:

  • Exit disguise mission for the Big Con and Agressive approaches.
  • Get security pass level 2
  • If you do the Aggressive or Silent & Sneaky approach, always do the Duggan shipments mission.
  • The patrol routes for Silent & Sneaky
  • The power drills for the deposit boxes. only if you are more than 2 players

What is the difference between the Level 1 and Level 2 security pass?

Level 1 cards are actually useless compared to level 2 cards.With a level 1 card, you'll need to hack each door that has a keypad.

Level 2 cards allow you to enter through all the doors without the need to hack them, you just need to swipe the card. It makes your heist much easier especially if you are doing the Silent & Sneaky approach.

Diamond Casino Heist Board

To unlock this prep mission you need to take a picture of the security tunnel of the Casino. It is right beside the racetrack.

How can I get the Sewer Tunnel as the entrance option?

During the Casino scoping mission you'll find the Sewer gate in the Sewer Tunnel. It is right across the street from the casino.

Do I need to buy the penthouse to carry out the Diamond Casino Heist?

Casino Heist Prep Board

No, you do not need the penthouse to carry out the Casino Heist, however some points of interest require you to have a VIP membership in order to access them, such as the Vault Blueprint in Agatha Baker's office.
