Game Rules
Everything you need to know to play and win
Blackjack
Objective
Beat the dealer by getting a hand value closer to 21 without going over. If your hand exceeds 21, you "bust" and lose immediately.
Game Setup
We use a 6-deck shoe (312 cards) with provably fair shuffling. The deck is shuffled fresh for each hand using cryptographic randomness that you can verify.
Card Values
Game Flow
Player Actions
Draw another card. You can hit multiple times until you stand or bust.
Keep your current hand and end your turn. The dealer then plays.
Double your bet on any two cards, receive exactly one more card, then automatically stand.
If you have a pair, split into two hands. Requires a matching bet for the second hand.
Payouts
Important: Blackjack vs. 21
Key Distinction
Blackjack (Natural) is specifically an Ace plus a 10-value card (10, J, Q, K) dealt as your first two cards. This pays 3:2.
21 with 3+ cards is just "21" — it beats hands under 21 but only pays 1:1, and loses to a dealer's natural blackjack.
Soft vs. Hard Hands
Soft Hand
Contains an Ace counted as 11. Example: A-6 = "Soft 17". You can hit without risk of busting (the Ace becomes 1 if needed).
Hard Hand
No flexible Ace. Example: 10-7 = "Hard 17". Hitting risks busting if you draw a 5 or higher.
Splitting Rules
- You may split any pair (two cards of the same rank)
- Cards must match by rank, not just value (K-K can split, K-Q cannot)
- Split up to 3 times (maximum 4 hands)
- Doubling after split is allowed
Special Rule: Split Aces
When you split Aces, each hand receives only one card. You cannot hit, stand, double, or re-split after splitting Aces. This is standard casino rules.
If you split Aces and receive another Ace, you cannot split again — you play that hand with the cards dealt.
Insurance
When the dealer's face-up card is an Ace, you may take insurance before play continues:
- Insurance costs half your original bet
- Pays 2:1 if the dealer has blackjack
- If dealer doesn't have blackjack, you lose the insurance bet and play continues normally
Tip: Statistically, insurance is not a favorable bet in the long run.
Dealer Rules
- Dealer must hit on 16 or less
- Dealer stands on soft 17 (Ace + 6)
- If dealer busts, all remaining player hands win
Not Offered
Surrender is not available. Some casinos allow you to forfeit half your bet against a dealer showing 10 or Ace, but we do not offer this option.
