How it works
Game Theory

Three forces. No randomness.

Every game is decided by spatial reasoning
and foresight alone.

Expand

Each piece radiates influence. You place only within your own reach.

Block

Pieces deny space to the opponent. Territory is contested from move one.

Cascade

Land in their block zone: pieces fall. Connected pieces cascade recursively.

5 piece types · 4 orientations · Infinite tactical lines.
