Ultimate Solo Cayo Perico Guide in GTA Online (2026)

Struggling to solo complete Cayo Perico in GTA Online for the Elite Challenge and maximize your loot? This ultimate guide has you covered.

This guide will cover the best Diamond Casino approach in GTA Online, along with what access points and POIs you need to get, with further information on loot, the best crew, setups, and route you need to take to ensure you’re walking out of the Diamond Casino with millions of dollars in rewards for your hard work.

Best Diamond Casino Heist Approach in GTA Online

The Big Con and Silent & Sneaky are the best Diamond Casino Heist approaches to alternate between. The reason you’ll want to alternate between these two specifically is that they maximize the profit you can get from the vault and minimize the risk of police attention that could cause your loot bags to lose value and cause your team to get killed.

The Big Con is great for allowing you to enter the vault with no issue at all, and Silent & Sneaky has a specific route that gets you to the vault with no issues. The alternative is Aggressive, which is not recommended, as although it’s beginner-friendly and can be done easily with randoms, it’s more dangerous due to waves of enemies, and the time-to-loot is lowered, meaning your total score will be of less value.

Best Access Points & POIs in Scoping Out the Diamond Casino

There are only two things you need to focus on for the Scoping Out mission in the Diamond Casino, and that’s the following Access Points:

• Security Tunnel Entrance (The Big Con) — This is located underneath the Diamond Casino within a tunnel that leads out to the race track. Simply take a picture with Snapmatic and send it to Lester.
• Side Door Entrance (Silent & Sneaky & The Big Con) — This is located to the right of the Diamond Casino, past the garage, and at the white door with a keypad. Send a photo of the door to Lester.

Best Loot in the Diamond Casino Heist (& How to Change Vault Contents)

The only loot you want to have in the vault for the Diamond Casino is Gold or Artwork. Cash has the least value and you’ll need a full squad to get it all, whereas Artwork can easily be obtained by two players, and Gold is the most valuable. So, try to focus on Artwork or Gold as your primary target. Here’s the value of each main loot in the Diamond Casino Heist:

If you want to change your Vault Contents, here’s what to do: Once you identify the loot in the vault during the Vault Contents mission, immediately call Lester and select “Cancel The Diamond Casino Heist.” Now, return to your Arcade and pay $25,000 for the heist setup, and the Vault Contents should be altered, but if not, leave the Arcade and repeat until you get something other than Cash.

Best Support Crew in the Diamond Casino Heist

For the Crew in the Diamond Casino Heist, you want to ensure that you are hiring the cheapest Gunman and Driver, as they truly don’t matter. However, for the Hacker, you’ll want the most expensive, as this gives you the most amount of time in the vault to loot. Here’s the best crew for the Diamond Casino Heist:

Paige Harris is a great Hacker, providing you with 3:25 in the vault; however, she can only be used if you own a Nightclub with a Terrorbyte, meaning you’ll have to spend a minimum of $2,383,000. Alternatively, you can get Avi Schwartzman for free if you destroy all 50 Signal Jammers, but this is time-consuming.

Best Prep & Setups in the Diamond Casino Heist (Silent & Sneaky)

Below is the only prep work you need to do for the best run of Silent & Sneaky in the Diamond Casino Heist:

• Unmarked Weapons: Micro SMG Loadout (Best loadout)
• Getaway Vehicles: Sentinel Classic (Fast getaway car)
• Hacking Device (essential)
• Nano Drone (essential)
• Vault Laser (essential)
• Vault Keycards (essential)
• Duggan Shipments (removes helmets from guards so you can get headshots)
• Security Pass Level 2 (allows you to access all doors)

Best Finale Prep Board in the Diamond Casino Heist (Silent & Sneaky)

Once you’re ready for the finale, return to your Arcade, assemble your crew of players, and copy out the prep board approach:

• Entrance: Staff Lobby
• Exit: Staff Lobby
• Buyer: High Level

Best Route in the Diamond Casino Heist (Silent & Sneaky)

With the prep board finalised, it’s time to break into the Diamond Casino and avoid detection from cameras and guards alike as you rob the place without them even knowing you were ever there. To begin, take the van parked outside your Arcade to the Casino’s parking area, and run towards the Staff Lobby, hugging the wall as you go to avoid the cameras so you can reach the locked door with your keycard undetected.

How to Get to the Vault Undetected (Silent & Sneaky)

From inside the Staff Lobby, equip the Stun Gun from the Pistol section of the weapon wheel, and hit the fuse box on the metal detector. Now, switch out to the Micro SMG, which is equipped with a suppressor, and take out the two guards stationed in the lobby. We recommend shooting the camera in this area with a Micro SMG so it doesn’t detect any bodies.

With the Staff Lobby cleared, shoot the guards in the CCTV by shooting the glass, as the bullets will pass through and they will not alert any guards. Now, one player can use the green button to open the secret vault room, to which another player can enter and loot for up to $90,000+. Just be mindful of the patrolling guard. After, head down the stairs and wait for the guard to come up so you can take him out, then the camera at the next set of stairs.

In the lower security area, there will be two guards stationed outside, ready to be taken out. Now, continue forward and approach the doors, but back off, as a guard will begin to patrol this route, so ensure he’s out of view of the camera so you can kill him, then push forward where you can enter past the room between the sliding doors to kill the guards stationed in the middle with headshots from behind the glass, and continue forward through the mantrap to the vault. Ignore the guard in the other room behind the glass, as he cannot see you.

How to Easily Hack the Diamond Casino Vault Doors

Once you’re in the vault, the timer immediately begins. You’re going to want to use a Diamond Casino hacking cheat sheet, which we’ve provided in the images above. The way the hacking minigame works is that you will have 1 of 4 potential fingerprints, and you need to match the fingerprint with 4 components. Above, you’ll find the corresponding components to each clone target to make hacking far easier.

You’ll have over 3 minutes to loot everything, but focus on hacking the locked doors first and leave the middle room for last. Just be sure to get out of the vault before the timer reaches 0, or you’ll alert the guards outside!

How to Escape the Diamond Casino Undetected (Silent & Sneaky)

Now that you’ve filled your loot bags and left the mantrap, you’ll be placed back in the security room. There’s only one guard to worry about here, and he’s back in the middle of the room, so kill him and go back up the same stairs you used to get down here in the first place.

You’re going to want to go through the CCTV room, where there are usually two guards stationed. Enter the door and kill them one by one, as they should be facing away from the door, and then use the green button to enter the secret vault again, as it’s restocked with more loot.

Now, shoot the metal detector’s fuse box with the Stun Gun again and exit through the same way you came in, which will begin a cutscene with NOOSE swarming the building. However, stay calm, as they haven’t spotted you yet. Head south, but hug the wall to the left. If the guard by the van is facing left, then take him out with a melee strike in stealth, as a headshot will alert the other guard. Follow the path to the left until you reach the getaway vehicle, and then either head through Vinewood for the police station and the helicopter to fly to the buyer, or stay in the tunnels underneath the Diamond Casino to evade the cops.
