あそびかた
色(いろ) ― 源から縁を伸ばして形を灯す。三つの縁座すべてに形を灯し、空の応手を一手耐えれば勝ち。
空(くう) ― 縁を断つ。源への道を断たれた形は、連鎖して滅する（縁滅）。色の完成を、決められた局数のあいだ防ぎ切れば勝ち。
断たれた縁は数手ののち結び直され、そして二度と断てない。縁を輪に厚く結んでおけば、一手では崩れない。

Engi — Form & Emptiness
On the board, all is originally emptiness. A form can exist only while it holds a thread of connection to a Source. The theme is 色即是空 — what fills will wane; what is bound comes undone.
How to play
Form — extend threads from the Sources and kindle shapes. Light all three Shrines, hold for one reply from the Void, and you win.
The Void — sever threads. A form cut off from every Source collapses, and the collapse cascades. Hold off Form's completion for the set number of rounds and you win.
A severed thread re-knits after a few moves, and can never be cut again. Bind your threads into a thick loop and no single cut will break it.
Features
A one-minute tutorial — learn “the thread” and 色即是空 on the real board, the first time you open the app.
Solo Trials — six stages of a steadily sharper opponent, on either side.
Free play — choose the round limit and the opponent's strength. Two players on one device, or watch two AIs.
Touch and resonance — iOS haptics on every connection, severance and collapse. Works fully offline.
Availability
Available on the App Store for iPhone and iPad.
