Each room has 4 cards. Resolve 3 of them — the remaining card carries into the next room. Survive until all 44 cards are gone to win.
Monsters ♣ ♠ — Fight unarmed (take full damage equal to the card's value) or fight with your weapon (see below).
Weapons ♦ — Equip to use in combat. Reduces damage: you take max(0, monster − weapon) instead of full damage.
Potions ♥ — Heal HP equal to the card's value, up to a max of 20. Only one potion can be used per room.
Example: equip a 7♦, fight a 5♣ — weapon binds to 5. Now you can't use it armed against a 6♣ or higher. Fight unarmed instead, or find a new weapon.
You can flee a room before resolving any cards — all 4 are discarded and 4 new ones appear. You cannot run two rooms in a row.
Take a standard 52-card deck and remove these 8 cards:
Remove all diamond face cards & ace: J♦ Q♦ K♦ A♦
Remove all heart face cards & ace: J♥ Q♥ K♥ A♥
You're left with 44 cards. Shuffle and play — black cards (♣ ♠) are monsters (face cards and aces are the toughest!), diamonds 2–10 (♦) are weapons, hearts 2–10 (♥) are potions. Original game by Zach Gage & Kurt Bieg.
