Six decks, one shared table
Up to ten seats play against the dealer with six decks reset for each round. Aim for a higher total than the dealer without going over 21. The dealer stands on soft 17 and draws the second card after players finish.
Use Hit or Stand on your turn. Double is available on the first two cards; equal-value cards can be split when permitted, up to four hands. Split aces receive one card each. There is no insurance or surrender.
Payouts and extra bets
Natural blackjack pays 3:2 profit, an ordinary win pays 1:1 and a tie returns the stake. Dealer blackjack takes the original bet only and returns additional split or double stakes. For a 1,000 SDICE natural blackjack, profit is 1,500 and gross return is 2,500.
Splitting and doubling require additional chips. Session funding and the displayed SOL processing budget are separate from the initial SDICE bet. Unused SOL is returned according to settlement accounting.
Fresh randomness for later decisions
MagicBlock VRF runs on Solana’s base layer for blackjack. Opening cards are batched in a request, later hits and replacements request fresh randomness, and the dealer’s turn is batched separately. A public, reusable future deck would let a player exploit later decisions; the draw protocol avoids relying on one such exposed future sequence.
The native program validates the scoped randomness callback and applies the card and payout rules. Use Verify round and the transaction history when available. This is a public-card draw protocol, not poker’s private multi-party shuffle, and it does not use an ephemeral rollup.
