The walls of Henstien Castle have never fallen. Tonight, that changes — unless you stop it.

The Krycon Warriors have crossed the northern mountains, and you are a Henstien Sentry, the last line of defence. Siege Chess is real chess, played out as a living battle on a storm-lit 3D battlefield where your pawns are armoured warriors who march to their squares and settle captures with their fists.

A REAL CHESS ENGINE, NO COMPROMISES

Full tournament rules — castling, en passant, promotion, check, checkmate and stalemate. Three opponents to face: a novice warrior, a seasoned fighter who searches three moves deep, and a master who thinks four moves ahead with positional judgement and capture-first tactics. Hard mode is pure chess: no arrows, no gimmicks, no excuses.

THE SIEGE IS LIVE

Choose Medium and the castle turrets open fire. Flaming arrows arc from the towers and rain onto the board, and any piece they strike is gone. Even your King is not safe — he has just three lives. On Easy, beware the hidden trap doors: four of them lurk somewhere beneath the battlefield, and any warrior who steps on one falls through the board and is lost for good. Only the Kings are too wise to fall for them.

A BATTLEFIELD THAT FEELS ALIVE

Warriors walk, charge and box. Arrows trail fire and burn down to embers where they land. Lightning cracks overhead and brings the rain in and out across a long game. Wolves howl in the distance and owls call once the fighting starts. Orbit the board freely, zoom in close, and watch every piece blast skyward when the final blow lands.

TWO PLAYERS, ONE BOARD

Pass and play against a friend on the same screen, or fight the Krycon alone. Win enough and the game will push you upward — Easy is taken away once you outgrow it, and Medium and Hard open as challenges you have to earn. Lose twice at a tier and you drop back down. Every victory is recorded on a persistent shield-marked scoreboard.

NEVER LOSE A BATTLE MID-FIGHT

Save and quit at any point, then resume exactly where you left off — position, turn, king lives and all.
