2 players · You against AI · Virtual-chip match

Choose one of two cards and bet on it. High usually wins, but a Two beats an Ace; the card you keep carries into the next deal.

1. 1

   Objective

   • Win the pot by making your opponent fold or by winning the one-card showdown. Both players start with 20 virtual chips; the match ends when one stack reaches zero.
2. 2

   Setup

   • Mix two French packs for 104 ordinary cards, excluding both Red Jokers (big jokers) and Black Jokers (small jokers). Deal two cards per player and pay a one-chip ante each deal. You lock a card and act first in the opening deal. The previous winner starts the next deal. After a tie, the first player switches.
   • Only rank groups are public: 8, 9, 10, J, Q, K and A are UP. 2–7 are DOWN. Signals show the counts in each group, without identifying the card backs or revealing the group of the locked card.
3. 3

   Playing a turn

   • On your turn, select one of your two cards and confirm to lock it face down. Betting starts only after both players have locked a card. Locked cards cannot be changed.
   • Check or bet when nothing is owed. Otherwise call, raise or fold. The minimum bet is one chip, and a raise must increase the wager by at least the last full bet or raise increment. Enter your total wager for this betting round, excluding the ante.
   • Going all-in commits your remaining chips and may fall short of the minimum raise. A short all-in does not reopen raising for a player who has already acted. Against an all-in opponent you may only call or fold. If you cannot cover a call, commit your remaining chips. Unmatched excess is refunded.

   Hand rankings

   • Compare only the two locked cards: A > K > Q > J > 10 > 9 > 8 > 7 > 6 > 5 > 4 > 3 > 2, with the sole exception that 2 beats A. Suits do not matter. Equal ranks tie.
5. 5

   Scoring and ending

   • Reveal both locked cards after betting. The stronger card wins the pot. Ties split it. If one player folds, the other wins the pot, but both locked cards are still revealed. Their ranks do not change the fold result.
   • For the next deal, discard the two played cards, keep the other card in each hand, draw one replacement each and pay the next ante. When fewer than two cards remain in the stock, reshuffle the discards and remaining stock while keeping held cards aside. Running out of chips loses the match. Restarting restores 20 chips each.
