Blackjack Simulator.

How to use the simulator.

Set your bet, then click on Deal. You get two cards face-up. The dealer takes one face-up and one face-down (the “hole card”).

• Hit takes another card. (Keyboard: H)
• Stand ends your turn. (Keyboard: S)
• Double doubles your bet, takes one more card, and ends your turn. (Keyboard: D)
• Bust over 21 and you lose. Closer to 21 than the dealer wins.
• Blackjack (Ace + 10-value on first two cards) pays 3:2.

What this simulator is, and isn’t.

This is a real blackjack engine. Same shuffle as the casino. Same dealer rules. Same payouts. Hands play out the way they would on a real table.

What it isn’t: a way to win money. Even with perfect basic strategy, blackjack has a small house edge of about 0.35% with these rules. Over thousands of hands, the math wins. The simulator is here to make those thousands of hands cost you nothing.

The shuffle is real.

Every hand is dealt from a six-deck shoe. That’s 312 cards. We shuffle with the Fisher-Yates algorithm using your browser’s crypto random number generator.

Translation: every order of those 312 cards is equally likely. Just like a real dealer’s hands.

No “house seed.” No “auto-loss” mode. No funny business.

The shoe reshuffles at 75% penetration. That’s the same point most live tables cut. Watch any Evolution Live stream and you’ll see the cut card go in around there.

Rules in play.

• 6 decks
• Dealer stands on soft 17 (S17)
• Double on any two cards
• Late surrender available
• Insurance offered when dealer shows Ace
• Blackjack pays 3:2
• Penetration: 75%

These rules are about as player-friendly as you’ll find. House edge: roughly 0.35%. That’s the lowest of any standard casino game.

Mistakes the simulator will catch.

• Hitting on hard 17. You’ll bust about 70% of the time. Stand.
• Standing on hard 12 vs dealer 7+. The dealer is favored to make a strong hand. Hit.
• Doubling on hard 12. A bad-hand double burns money fast. Save your doubles for 9, 10, 11.
• Insurance bets (when we add them next). The math says no almost every time. The dealer doesn’t care that you’re “due.”

If you don’t know the right move, memorize basic strategy. It’s the closest thing to a cheat code in casino gambling.

Want to feel it? Drill 500 hands.

Set your bet to $25. Hit Deal 500 times. Use basic strategy on every hand.

Starting at $1,000, you’ll likely end somewhere between $300 and $1,600. The math says you should lose about $54 over 500 hands. But variance is bigger than the math at this volume. One bad swing is normal.

Want to feel the math actually win? Try 5,000 hands. Expected loss: around $540. Variance shrinks. The house edge becomes visible.

That’s it in action. The simulator lets you feel it without bleeding real money.
