Zent Hi-Lo.

Fresh deck for each draw

Ranks run from Ace (1) to King (13). Every card is drawn independently from a fresh 52-card deck; all ranks are equally likely. Guess strictly higher or lower. A tie loses. From rank r, Higher has (13−r)/13 winning chance; Lower has (r−1)/13. A direction with zero chance is unavailable.

After one correct guess you may collect or continue, up to five correct guesses, which automatically collect. If your successful predictions had w₁…wₖ winning ranks, your total-payout multiplier is 0.97 × 13ᵏ ÷ (w₁×…×wₖ). A wrong prediction loses the stake. Theoretical return at a collection point: 97% before rounding.

All payouts shown are totals including any returned stake. Payouts round down to a whole pesewa. A theoretical return describes long-run mathematics, not a promise for your session. Game outcomes are generated on the server. This version does not claim independent certification or a player-verifiable seed protocol.

GHS rounds use your one main balance. Free practice does not use or create a wallet. A refresh can recover your current round; account breaks stop new rounds while existing rounds can be completed.
