Shichijin (七陣) is the perfect-answer puzzle game. No luck, no timers, no ads. There is only one placement that solves each board — and the art is finding it.
THE CORE LOOP
Deal yourself a hand of seven samurai types. Choose up to four to place on the scattered board. Press play and watch the battle resolve with perfect determinism: the strongest piece acts first, damage is always fixed, and the same board always plays out the same way. Your only decision is WHERE your pieces stand.
Win by defeating the whole army — or, on certain boards, by slipping past the guards and cutting down the Daimyō alone. Winning is often easy. Finding the placement that keeps every piece alive? That's the real puzzle.
THE PIECES
Seventeen warrior types, each with a fixed role:
• Yari — a spear that strikes the nearest enemy at range
• Teppō — a matchlock that looses a salvo, hitting every foe nearby
• Ninja & Kunoichi — one-shot assassins that leap across the field for a single killing blow
• Onmyōji — blesses nearby allies with extra strength
• Castles, towers and pagodas dot the field — impassable, each aiding a neighbouring unit: a castle's walls soften blows, a watchtower's high ground adds strength, a pagoda extends reach
THE JOURNEY
• 100 boards a season, all open from day one, sorted easy → impossible. Play in any order, at your own pace.
• 700+ hand-crafted boards in all. Buy tougher one-off challenges with Koban.
• A 101-rank world ladder: your earned bushō title is your name. Climb from Ronin all the way to Oda Nobunaga at the summit. Each season resets and crowns its champions.
• Analysis: reveal the perfect line — the exact placement and the reasoning — and learn why it wins.
• The hardest boards are named in homage to real Sengoku battles.
THE PHILOSOPHY
No ads. No randomness. No login required. Just you, 700+ puzzles, and the quiet satisfaction of finding the one right answer.
Play on your time. Learn at your own pace. Climb if you want to; ignore the ladder if you don't. The puzzle is the point.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Fixed a mobile issue where a piece's description could cover the bottom of the board while you were placing — the whole board stays tappable now.
• The season screen shows a live countdown to the next reset, and when a new season begins it shows how you finished the previous one (title, rank and score).
Thanks for playing — climb the ladder.
