GTA Online Diamond Casino Heist Money Guide — The Ultimate CRIMENET Playbook

There are many ways to make money in GTA Online.

You could grind nightclub stock. You could flip cars. You could sell cargo.

Or — you could do what every self-respecting lunatic does: rob the most heavily guarded casino in the city wearing a stolen janitor’s outfit and blind confidence.

This isn’t a guide for amateurs who say, “We’ll figure it out when we get there.”

No. This is CRIMENET, where we figure it out for you — with spreadsheets, sarcasm, and several lawsuits pending.

TL;DR — The Lazy Man’s Million

If you can’t be bothered to read, here’s your cheat sheet:

• Approach: Big Con (Gruppe Sechs). Walk in like you pay taxes, walk out like you own the place.

• Hacker: Paige Harris. She’s 9% of the take, but her brain’s worth three interns and a thermos of coffee.

• Vault target: Gold or Art. Cash is for peasants, Diamonds are for holiday events.

• Buyer: High-level. Always. Yes, he’s far away, but you just stole three million dollars — stretch your legs, fatty.

• Duggan Shipments: Hit at least six. The guards will go from “Call of Duty tryhards” to “drunk mall cops.”

• Damage: Each bullet to your pretty little face costs you thousands. Don’t get shot.

• Setup fee: $25,000. Lester’s “processing fee” for doing absolutely nothing.
  

Do this right, and you’ll make $1.1M+ per player in about 15 minutes.

Do it wrong, and you’ll make the same amount as a barista — except you’ll die halfway through your shift.

The Vault, Explained by a Man Who’s Been There Too Many Times

Each vault type has a distinct personality disorder:

Vault Loot	Normal	Hard	Notes
Cash	$2.1M	$2.3M	Worth less than your therapist’s opinion
Artwork	$2.35M	$2.58M	Quick grab, smells of class
Gold	$2.58M	$2.84M	Heavier than my ex’s emotional baggage
Diamonds	$3.29M	$3.62M	Only available when Rockstar feels generous

If Diamonds return (like an ex promising “this time it’s different”), drop everything and farm them.

Crew & Cut — The Math Behind Madness

• Lester: Takes 5% for existing.

• Setup fee: $25k, gone faster than your dignity in a strip club.

• Player minimum: 15% each. Because apparently human rights exist in Los Santos now.

• Support Crew:

  • Hacker: Paige (9%) or Avi (10%) if you enjoy overpaying for nerds.

  • Gunman: Karl (5%) — cheap, cheerful, can’t aim.

  • Driver: Karim (5%) — the Uber Eats of getaway drivers.

• Buyer laundering:

  • High = 0% fee

  • Medium = 5%

  • Low = 10%Always choose High, unless you have the patience of a teething toddler.

The Perfect Setup — Big Con Edition

This isn’t stealth. This is theatre.

You’re pretending to be security guards, strolling into a vault worth millions, and nobody questions it because Los Santos is powered entirely by cocaine and incompetence.

Crew loadout:

• Approach: Big Con (Gruppe Sechs)

• Hacker: Paige Harris

• Gunman: Karl Abolaji (or “Discount Rambo”)

• Driver: Karim Denz (because you can steal better cars anyway)

• Buyer: High-level

Vault Time:

• Paige = ~3:25 undetected

• Avi = ~3:30 undetected

• Cheap hackers = about 2 minutes, which is barely enough to sneeze and grab one gold bar.

Preps — What Actually Matters

You don’t need all 14 preps. Some exist purely to waste your time.

Here’s what’s worth it:

✅ Vault Keycards – Shaves off precious seconds.

✅ Guard Patrol Routes – Because guessing is for toddlers and drunks.

✅ Hacking Device – Kind of the whole point.

✅ Duggan Shipments – Destroy at least six to stop the guards looking like juggernauts.

✅ Security Intel – Knowledge = profit.

❌ EMP Device – Useless unless you enjoy paying for fireworks.

❌ Masks & Drills – Pure fashion nonsense unless you’re roleplaying as a plumber.

Duggan Shipments — The Secret Sauce

Destroy six or more, and the guards downgrade from US Marines to bored mall cops.

Do all ten, and they’ll start carrying airsoft guns.

Community-tested breakpoints:

• 3 shipments: helmets start disappearing.

• 6+: full armor reduction.

• 10: they die if you look at them funny.

Inside the Vault — Grab Like You Mean It

Each second counts.

• Art: Light, fast, and oddly satisfying. Two players can clean the room before the hacker finishes a Red Bull.

• Gold: Heavy. Assign two mules and alternate bags.

• Cash: Boring. Grab it only if you hate yourself.

• Diamonds: Jackpot. No drills, no drama, just dopamine.

Deposit boxes: Contain anywhere between $0–$5k. You’ll lose more time than you gain.

Daily Vault Safe: $50–100k, right next to the CCTV room by the elevator.

If you forget it, congratulations — you just tipped Lester.

The Escape — Don’t Get Shot

Each bullet you take costs around $2,000 in lost take.

So unless you want to roleplay a Swiss cheese, avoid combat.

Best Route:

• Exit via Staff Lobby, change into disguises, grab a random car from the street, and drive to the High buyer.

• Ignore the marked getaway vehicles unless you enjoy slow-motion misery.

Fun Fact: The “Aggressive” approach gives you less vault time and more gunfire. It’s basically Hard Mode for masochists.

Example Math — Why You Should Listen

Scenario A (2 Players, Gold, Hard Mode)

• Gross: $2,843,500

• Lester (5%): –$142,175

• Support crew (19%): –$513,251

• Final pot: $2,188,074

• Split 50/50: $1.09M each

Scenario B (3 Players, Art, Hard)

• Gross: $2,585,000

• Lester (5%): –$129,250

• Crew (19%): –$492, etc.**

• Final: ~$1.95M

• Split 40/30/30 → $783k / $587k / $587k

That’s roughly a million each per run — faster than most people can spell “Oppressor Mk II.”

The Human Element

If you’re hosting, don’t be generous. You’re the brains, the financier, and the only one with the arcade mortgage.

Give your crew just enough cut so they don’t whine on Reddit — around 30% if you’re feeling saintly, 15% if you’re feeling yourself.

The CRIMENET Formula

Run Big Con with Paige, hit six or more shipments, don’t get shot, and always sell to a High buyer.

Art and Gold are your bread and butter; Diamonds are your champagne.

You’ll make more cash than a TikTok crypto guru and look cooler doing it.

So go forth, criminals.Put on your fake badge, grab a duffel bag, and remember — this isn’t a robbery.

It’s performance art.
