Features ⚔ HP-Based Combat Every piece has health and attack stats. Moving onto an enemy square triggers a fight — the defender loses HP equal to the attacker's attack. If the defender survives, the attacker is repelled and the turn ends. Only a killing blow earns the square.

Piece HP ATK Ability ♙ Pawn 40 10 Strength in Numbers — Adjacent friendly pawns gain +1 HP at end of turn ♖ Rook 50 20 Its Hammer Time — Attacks pierce through to the enemy behind the target ♘ Knight 60 12 Hippity Hoppity — First attack opens a chain: hit up to 3 enemies in sequence ♗ Bishop 30 20 I'm Pope-ing Off — Active: heal all friendly pieces in 3×3 area by 7 HP ♕ Queen 100 25 Stunning Beauty — Hits stun the target; HP Tax — deals +10% of target's current HP ♔ King 35 4 King's Choice — One powerful ability chosen before the match 💀 Last Stand When a piece is about to deliver a killing blow, a Last Stand challenge triggers — a full-screen duel screen where both pieces rush toward each other. The attacker must correctly type 5 random letters within 7 seconds to execute the capture. Fail, and the turn ends with nothing gained.

👑 King's Choice Before each match, both kings independently choose one once-per-game ability:

Higher Morale — Spawn a friendly Rook on any empty square; King recovers 25% HP Za Wardou (Toki wa Tomare) — Time stops: the opponent loses their next turn Dirty Deeds — Swap the King's position with any other friendly piece Epitath — Reverse the opponent's last move entirely 🌋 Battlefield Maps Four distinct battlefields, switchable at any time from the sidebar (switching resets the match):

Map Hazards ⚔ Standard Classic board — no environmental effects 🌋 Hybrid Volcano tiles deal 10 damage/turn; Repair squares grant +5 ATK permanently 🌊 Flood Water tiles block movement and line-of-sight for sliding pieces 🌫 Foggy Enemy pieces in fog are invisible unless a friendly piece is adjacent Each map tile has a live CSS animation — lava flows, waves shimmer, fog drifts.

🎨 Visual Polish Animated intro screen with game overview before every session Floating lava embers, water ripples, and fog wisps surround the board based on active map Per-piece HP bars, floating damage numbers, stun indicators Attack animations with ghost pieces flying across the board Clash, death-spin, pierce, heal, and ability-specific visual effects Ambient board glow that changes color with the active map 🚀 Getting Started No installation needed — open index.html in any modern browser.
