Chess you already know.
Combat you've never seen.

Five layered systems make every game a tactical puzzle. Mastering chess movement is just the warm-up.

Damage & HP

Each piece deals damage and has hit points (Damage/HP). Pawns 2/2, majors 2/4, Queen 4/4. Pieces survive attacks — every move is a combat decision, not a binary capture.

Area-of-Effect

Rooks cleave perpendicular, Bishops splash diagonal corners, Queens sweep a 3-square cone in their movement direction. Position matters — not just targets.

Buff Auras

Knights stack offensive auras (×2 damage per stack). Kings shield neighbors (½ incoming damage). Stack Knights for devastating combos.

Pawn Counter-attacks

Hit a pawn but don't kill it? It strikes back. Direct hit or AoE — surviving pawns retaliate before the dust settles.

HP Win Condition

No checkmate puzzles. No stalemate stalls. The first King to reach 0 HP loses. Combat is decisive — but five draw conditions keep games clean.

Promotion Choice

Promote to any missing major piece — or grab a second Queen if all slots are filled. Promoted pieces enter at full HP.

Game modes

Three ways to compete.

From a quick warm-up against the AI to ranked grinds against humans, every mode plays the same combat-rich rules.

Five tiers of AI — built for combat chess.

This isn't a bolted-on chess engine. Our AI uses iterative-deepening minimax with α-β pruning that natively understands HP, AoE damage, buff auras, and pawn counter-attacks.
