Blackjack — Rules & Provably Fair
How to play
Standard blackjack: get closer to 21 than the dealer without going over. Cards 2-10 count face value, J/Q/K count 10, Ace counts as 1 or 11 (whichever helps).
- Dealer stands on all 17s — including soft 17.
- Blackjack pays 3:2 (2.5× total return).
- Double available on any 2-card hand if balance allows.
- Split two same-rank cards into two hands — no re-splitting.
- Split aces: each hand receives exactly one card, no further actions. A resulting 21 pays 1:1, not 3:2 (it's not a "blackjack" by rule).
Insurance
When the dealer's up-card is an Ace, you can take insurance for half your bet. Pays 2:1 if the dealer has blackjack. If you have blackjack and take insurance, the result locks at even money (1:1, 2× total) — no further reveal needed.
House rule: if you hold a splittable pair AND the dealer shows Ace, insurance is not offered — split takes priority.
Shoe modes
- 6 decks — 312 cards, reshuffled when below 78.
- 8 decks — 416 cards, reshuffled when below 104.
- Unlimited — continuously refreshed 4-deck shoe, remaining count hidden so card-counting gains no edge.
Provably fair
Each shuffle uses a fresh HMAC-derived Fisher-Yates permutation of the shoe. Reproducible by replaying server seed + client seed + nonce. Cards are drawn from the top of that permutation in order.
