Blackjack rules

A fresh 52-card deck is shuffled for each round. The dealer stands once ahead of the player or on any 17, blackjack pays 3:2, double is available only as the first action and splitting is not available.

How a round works

  1. Deal two cards to the player and dealer.
  2. Hit for another card, stand, or double once as the first action.
  3. Below 17, the dealer draws only until its hand beats yours; the closest valid hand wins.

Payouts and settlement

Normal win returns 2x, natural blackjack 2.5x, push 1x and loss 0. A doubled hand doubles both stake and resulting payout.

RTP, risk and strategy

RTP depends on player decisions. The displayed estimate uses a fixed hit-below-hard-17/soft-18 strategy without doubling.

RTP is measured over a very large number of wagers. A short session can finish far above or below it, and no strategy guarantees profit.

Fairness and verification

The shuffled deck is committed before dealing and its order is revealed after settlement.

Does changing animation speed affect the result?

No. Visual speed, turbo controls and browser performance do not change a result generated and settled by the server.

Where can I verify a disputed result?
