Setup
Each player has an identical 32-card deck in their color.
Each player uses a 32-card deck in their chosen color (red or blue). The deck contains: 5 Punch cards valued 1, 5 Punch cards valued 2, 5 Punch cards valued 3, 5 Do Nothing cards (0), 5 Block cards (X), 5 Dodge and Punch Back cards (-/*), 1 Stamina card, and 1 Blank Boxer card. Both decks are identical in composition; only color differs.
Setup
Each player starts each match with 10 stamina, tracked by overlapping two cards.
Each player uses a Stamina card and a Blank Boxer card. At the start of every match, the Blank Boxer card is positioned on top of the Stamina card to show a stamina value of 10. When stamina is lost, the Blank Boxer card is slid downward to cover higher numbers and reveal the lower current value. When stamina is gained, the Blank Boxer card is slid upward to reveal the higher value. The maximum stamina at any time is 10.
Restriction
A player's stamina cannot exceed 10.
Stamina is capped at 10 at all times. This applies during breaks and whenever a Do Nothing card grants a stamina point. If a stamina gain would push a player above 10, it is capped at 10.
Turn structure
Each match has 3 rounds of 10 card exchanges; breaks follow rounds 1 and 2.
A match consists of exactly 3 rounds. In each round, both players play exactly 10 cards, one at a time, simultaneously revealed. After round 1 (if no knockout), there is a break where both players regain 3 stamina. After round 2 (if no knockout), there is a break where both players regain 2 stamina. The maximum stamina after any break is 10. There is no break after round 3; instead, the match ends.
Setup
In standard rules, players randomly deal themselves 10 cards per round.
Under standard rules, at the start of round 1, each player deals themselves 10 cards face down from their shuffled deck, then picks them up. At the start of round 2, each player deals themselves another 10 cards. The remaining 10 cards are used in round 3 without additional dealing. If a player has 4 or 5 cards of the same value in their round 1 or round 2 hand, they may reveal this to their opponent and reshuffle and re-deal a fresh hand of 10.
Setup
In advanced rules, players freely draft their 10 cards before each round.
Under advanced rules, players do not deal randomly. Instead, before round 1 each player freely selects any 10 cards from their entire 32-card deck to form their hand. After round 1, they freely select their next 10 cards from the remaining 22 cards. In round 3 they play with the last 10 remaining cards. All other rules remain the same.
Turn structure
Both players choose and reveal one card simultaneously each exchange.
On each exchange within a round, both players secretly choose one card from their hand and place it face down in the center of the table. Both cards are then revealed at the same time. Effects are then calculated and resolved together.
Card play
A Punch card hits an opponent who plays a non-Punch card (except Block) for its full value.
A Punch card (value 1, 2, or 3) deals damage equal to its value to the opponent if the opponent plays a Do Nothing card (0) or a Dodge and Punch Back card against a non-punch (i.e., opponent plays Dodge but no punch was thrown — see dodge interaction). When an opponent plays a Do Nothing card and you play any Punch card, the Do Nothing player is hit by the full punch value.
