A minimalist grid deduction puzzle designed for focus, logic, and clarity. Solve mathematically verified boards offline, or preserve progress with Google Play Games.
Solved in 2 moves • Perfect Target Score
Three fundamental rules govern every board state, from small 3×3 grids to complex layouts.
Touching any tile toggles its state immediately. Active tiles switch off; dark tiles illuminate.
Inversion propagates in a cross formation, simultaneously toggling adjacent tiles to the top, bottom, left, and right.
The objective is complete eradication of active tiles. Reaching a clear board within target moves secures a three-star rating.
Engineered for focused play, respecting device battery and player attention.
Every level is algebraically verified via matrix inversion. Solutions are reachable through pure deduction without speculation or random trial.
Campaign progression, move counts, and level records remain stored locally on your device via Room Database and DataStore.

Optional cloud synchronization preserves your earned stars, level clearances, and achievements across devices via official Google Play Services.
