How it works

Seven formations. One elegant answer.

Every board is a fixed problem with zero randomness. Nothing is left to chance — only to you.

STEP 一

Draw seven

Each board deals a hand of seven — drawn from seventeen warrior types: spears, matchlocks, assassins, mystics and more.

STEP 二

Place four

Position up to four of them across the scattered zone. Where each one stands is the whole game.

STEP 三

Let it resolve

Press play and the battle settles itself — strongest piece acts first, damage is fixed, the same board always plays out the same way.

STEP 四

Find the perfect line

Winning is often easy. The real puzzle is the one placement that keeps every piece alive — the max score.

The season & the ladder

Climb from Ronin to Nobunaga.

A season is 100 boards, all open from the start, sorted easy→impossible. Play them in any order, at your own pace. 700+ hand-crafted boards in all.

A season of 100 boards

No daily gate, no waiting. Every board is unlocked from day one — chase the early wins or go straight for the impossible.

Draw seven. Place four.

Win by defeating the whole army — or, on some boards, by cutting down only the Daimyō. Every board has one right answer. Can you find it?
