There is no magic, no health points, and no complex numerical calculations. We return to the primitive: transforming real-world food chain relationships into win-loss logic. Knowledge is your best weapon.

Core Gameplay: Strategy, Prediction, and Counter-strikes

Every duel is a gamble for survival.

• Strategic Play: Players take turns playing face-down cards, revealing only partial biological attributes.
