## What is SlapJack?

SlapJack is a skill-based blackjack platform where you compete against other players — not the house.

Choose your game, pick your buy-in, play blackjack, and compete for real cash prizes.

Whether you want to go head-to-head, battle a table of 10, or take on a larger tournament field, SlapJack gives you multiple ways to put your blackjack skills to the test.

THREE WAYS TO PLAY

BATTLE — 1v1 BLACKJACK

Go head-to-head against another real player. Choose your buy-in, get matched with an opponent, and play your own 6-deck shoe. When the match ends, the player with the higher chip total wins.

SIT-N-GO — 10 PLAYERS. TOP 3 GET PAID.

Take your seat in a 10-player Sit-N-Go. Once the table fills, the competition begins. Build the highest chip total you can and finish in the Top 3 to cash.

TOURNAMENTS — BIGGER FIELDS. BIGGER COMPETITION.

Enter scheduled blackjack tournaments and compete against the entire field. Follow the leaderboard as you play and fight your way into a cashing position. The Top 30% of the field gets paid.

Free-roll tournaments may also be available, giving players opportunities to compete for cash prizes without a buy-in.

YOUR CARDS. YOUR DECISIONS.

Every player plays their own blackjack game, starting with $100k in chips. Your hits, stands, doubles, splits, surrenders, bets, and strategy affect your result.

Manage your chip stack, know when to take a risk, and make every hand count.

There’s no poker face. No bluffing. Just blackjack decisions and the race to finish with the most chips.

REAL PLAYERS. REAL COMPETITION.

SlapJack turns blackjack into a competitive experience.

Challenge another player in a Battle. Grab a seat in a Sit-N-Go. Enter a tournament and climb the leaderboard.

Compete against players, not the house.

Deposit. Play. Win. Cash Out.
