Classic single-deck blackjack

Step-by-Step Guide

  1. 1

    Set your bet and click Deal. You and the dealer each receive two cards (one dealer card face-down).

  2. 2

    Choose your action: Hit (take another card), Stand (keep your hand), Double Down (double bet, take one card), or Split (if you have a pair).

  3. 3

    Try to get as close to 21 as possible without going over (busting).

  4. 4

    After you stand, the dealer reveals their hole card and plays by fixed rules (hit on 16 or less, stand on 17+).

  5. 5

    Win by having a higher hand than the dealer without busting. Blackjack (Ace + 10-value) pays 3:2.

Provably Fair System

A single 52-card deck is shuffled using Fisher-Yates seeded by HMAC-SHA256(server_seed, client_seed:nonce). Cards are dealt sequentially from the shuffled deck. The entire deck order is determined before the hand starts, ensuring no cards can be changed after dealing.

Visit the Fairness Verification page to verify any past round with your seeds.
