03 / BEFORE THE FIRST DEAL
Good questions.
Straight answers.
A clearer game starts with knowing what to expect.
Can I play blackjack for free without a wallet?
Yes. The practice table starts with 100 virtual credits and needs no wallet, account, or deposit. Practice credits have no monetary value and cannot be withdrawn. The USDC table is a separate mode.
What are the blackjack rules at ACE21?
The table uses six decks. The dealer stands on all 17s, including soft 17. A natural blackjack pays 3:2. You can double on any first two cards and after a split, and split up to three times. Insurance and surrender are not offered.
What does a 3:2 blackjack payout mean?
A natural blackjack is an ace and a ten-value card in your first two cards, before a split. A winning 2-credit blackjack returns 5 credits: your original 2 credits plus 3 credits in profit. If the dealer also has blackjack, your bet is returned.
How is on-chain blackjack verified?
In on-chain mode, a cryptographic commitment is recorded before the deal. After settlement, the revealed seeds and game transcript can be checked against that commitment. Verification checks the recorded hand; it does not guarantee a win. Browser practice does not produce an on-chain proof.
What do I need for the USDC table?
You need a compatible wallet, USDC for your wager, and ETH for network fees on the configured chain. Double and split add another wager. Review the table rules and only play with an amount you can afford to lose.
