GTA Online Casino Guide: Blackjack, Three Card Poker, Roulette and Slots

GTA Online's Diamond Casino has four table and machine games worth learning: blackjack, three card poker, roulette and slots. Each one runs on real casino rules with a house edge built in, and the game you pick changes your odds more than any "lucky" streak ever will.

Essentials

• The Diamond Casino & Resort sits on Vinewood Racetrack in West Los Santos.
• Walking through the front doors gets you a free Diamond Casino Membership, which unlocks every table game, the Lucky Wheel and the casino penthouse.
• Chips are the casino's currency: 100,000 GTA$ buys 100,000 chips, and you can hold a maximum of 50,000 chips at once.
• Slot machines pay out around 98.7% on most machines, the best odds of any game in the building.
• In more than 50 countries, Rockstar disables real-money chip purchases and some gambling minigames entirely because of local gambling law.

How to Get Chips at the Diamond Casino

Chips are bought with in-game GTA$ at cashier windows or via the casino app on the in-game phone, at a 1:1 rate. You can also earn chips as prizes from the Lucky Wheel, the Inside Track horse betting terminal or the casino story missions.

The chip cap matters: you cannot hold more than 50,000 chips at any time, so once you hit the ceiling you have to cash out before buying more. Rockstar has, in the past, let players in supported regions top up chips with real money through microtransactions, but that option is switched off across a long list of countries, including Belgium, the Netherlands, Australia and several others where regulators treat any real-money, chance-based purchase as gambling. If the casino cashier will not sell you chips, that is almost always why. GTA$ purchases are unaffected everywhere; only the real-money conversion is restricted.

Blackjack: Rules and Basic Strategy

Blackjack tables sit in the main gaming hall, the high-stakes area and the penthouse. The rules mirror a standard Vegas shoe:

• The dealer uses four shuffled 52-card decks and deals two cards to every player and to themselves, with one dealer card face down.
• Aces count as 1 or 11, face cards count as 10, and the goal is to get closer to 21 than the dealer without busting.
• The dealer stands on soft 17, which is a small edge in the house's favor compared to tables where the dealer hits soft 17.
• You can stand, hit, double down (one extra card, doubled bet) or split a pair into two hands.

Basic strategy still applies here just like in a real casino: always split aces and eights, never split tens, stand on hard 17 or higher, and double down on 11 against any dealer card except an ace. Blackjack has the lowest house edge of any table game in the building when you play correct basic strategy, which is why regulars treat it as the default choice over three card poker or roulette.

Three Card Poker: Ante, Pair Plus and When to Fold

Three card poker is the most misunderstood table in the casino because it is really two separate bets:

• Ante bet: you are dealt three cards face down and go head-to-head against the dealer. Raise (matching your ante as a "play" bet) or fold. The dealer needs Queen-high or better to qualify; if the dealer does not qualify, your ante pays even money and the play bet pushes.
• Pair Plus: an optional side bet that pays out on your own hand regardless of the dealer, starting at a pair.

Hand	Ante/Play payout	Pair Plus payout
Straight flush	5 to 1	40 to 1
Three of a kind	4 to 1	30 to 1
Straight	1 to 1	6 to 1
Flush	1 to 1	4 to 1
Pair	1 to 1	1 to 1

Notice that in three card poker a straight beats a flush, the opposite of Texas Hold'em, because with only three cards a straight is statistically rarer. The standard basic strategy is simple: play (raise) any hand of Queen-6-4 or better, and fold anything weaker. Sticking to that single rule gets you close to the game's built-in house edge instead of bleeding chips on marginal hands.

Roulette: American Wheel, Best and Worst Bets

GTA Online's roulette table uses the American layout, with both a single 0 and a 00 pocket, which pushes the house edge higher than the European single-zero wheel found in most real casinos. You can bet on:

• A single number (35 to 1 payout, the highest-risk, highest-reward bet)
• Red or black, odd or even, or high/low (roughly even-money bets with the best win frequency)
• Rows, columns or groups of numbers for payouts in between

You can place up to 10 individual bets per spin to spread your risk across the table. If you are chip-conscious, stick to the outside bets (red/black, odd/even, high/low): they will not make you rich in one spin, but they lose slower than chasing single numbers, and the double-zero house edge means the long game always favors the casino here more than at the blackjack table.

Slot Machines: The Best Odds in the Building

Slot machines are pure luck, no skill involved, run on a random number generator with every spin independent of the last. Minimum bets range from 5 to 500 chips depending on the machine, with a maximum bet of five times that minimum. Most machines return around 98.7% of what they take in over time, which is a far better payout rate than you will find in most real-world casinos, though a handful of themed machines (like Republican Space Rangers) run closer to a 50% RTP, so check which machine you are sitting at before feeding it chips.

Which Casino Game Actually Has the Best Odds?

Game	House edge (approx.)	Skill involved
Slot machines (standard)	~1.3%	None
Blackjack (basic strategy)	Low, single digits	High
Three card poker (ante only, correct strategy)	Moderate	Moderate
Roulette (American, single number)	High	None

If you only care about grinding chips efficiently, standard slot machines and correctly-played blackjack beat three card poker and roulette over a long session. If you are playing for fun and the thrill of a big single-number roulette hit or a Pair Plus straight flush, the odds matter less than the story you walk away with.

Casino Story Missions and Free Spins

Buying the Diamond Casino Membership also unlocks the casino heist storyline and a daily free spin on the Lucky Wheel, which can pay out cash, RP, clothing, cars or a shot at the podium vehicle. For a full breakdown of those odds, see our GTA Online Lucky Wheel odds guide. If you have already put in your casino chip time, the natural next step is planning the Diamond Casino Heist itself, which pays out far more than any table game ever will.

Casino Chips vs. Other Money Methods

Casino games are entertainment first, income second: even a hot blackjack or slots session rarely beats running businesses or heists for GTA$ per hour.
