Having different approaches to the new casino heist is one of the major new features added to GTA Online via the DLC. One of the three approaches is called The Big Con approach (the others being the Aggressive and Silent and Sneaky approaches).

There are three general approaches to the Casino heist, all with specific preps, excluding the general preps common for all of the approaches. Some of the preps are optional, while some of them are multivariate (Ex: different getaway cars, different gun loadouts, different disguises).
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 $50,000 to $100,000 to be in there. It will vary from heist to heist though.

The Diamond Casino Heist is a new heist job in GTA Online's Diamond Casino and Resort update. The casino heist is by far the most complicated heist GTA Online players have seen, but it offers some good ways to make a lot of money along the way.

If you don't know how to start the Casino Heist or if you are stuck on one of the missions, our walkthrough on how to complete this job in GTA Online is outlined below.

Step 1: Buy an Arcade

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

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:

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

When you're outside the casino, you can safely deliver the v
