Blackjack Rules

Blackjack (21) is the classic card game played against the dealer. The aim is to make a hand higher than the dealer's without going over 21. It is played with the same account and the same balance as 101 Okey; every hand is dealt on the server.

Card values

• 2–10 count their face value; jack, queen, king count 10.
• Ace counts 11; if the hand would go over 21 it counts 1 (a "soft" hand).
• 21 with the first two cards (ace + ten-value card) is a blackjack and pays 3:2.

How to play

• Pick a chip or type your bet and press DEAL. You get two face-up cards, the dealer one face-up and one face-down card.
• HIT: one more card. If you go over 21 the hand busts and the bet is lost.
• STAND: keep your hand; the dealer plays.
• DOUBLE: only with the first two cards; the bet is placed again, you get one card and the hand ends.
• SPLIT: if the first two cards have the same value the hand is split in two and the bet is placed again for the second hand; each hand is played separately (one split only; split aces get one card each).
• The dealer stands on all 17s (including soft 17) and draws on 16 or less. The dealer reveals the face-down card when you are done.

Payouts

• Blackjack: 3 to 2 (100 bet → 250 returned)
• Win: 1 to 1 (100 bet → 200 returned)
• Push (equal hands): the bet is returned
• If both you and the dealer have blackjack it is a push. A 21 on a split hand is a normal 21, not a blackjack.

Bet limits

• The first bet of a hand is at least 10 and at most 5,000; bets are multiples of 10. Doubling and splitting need the bet amount in your balance.
• The bet is taken from your balance when the cards are dealt; the win (including your bet) is added when the hand ends. An unfinished hand continues where you left it when you return.

Fair play and payouts

• Fair payouts: the shoe is shuffled with a provably fair key every hand and can be verified; the Provably fair window in the game shows how. A push always returns the bet.
• For every hand a 6-deck shoe is shuffled with provably fair seeds (HMAC-SHA256), independent of your bet and your moves. The next card is fixed in advance; hitting cannot change the outcome. The server seed hash is shown in advance; when you rotate the seeds the old server seed is revealed and you can verify your past hands yourself.
• You can bet in only one game at a time.
• In case of malfunction all pays and plays are void.
