A stained-glass logic puzzle
GLASS
Four colors. One rule.
Fill each window with four colors. Matching colors can't touch. Take your time, follow the pattern, and let the music grow as the light comes through.
Coming soon to iPhone and iPad
The rule
Neighbors never match.
Every pane you color narrows what can go next to it. One choice changes the next, until the whole design locks into place. It's simple to learn and quietly absorbing.
The light
Bring every window to life.
Each window starts as clear glass. Color by color, the light floods in, until the finished piece glows against a dark, gallery-like backdrop.
The music
Music that moves with you.
An adaptive score builds as you solve, layer by layer, so the music finishes when the window does. No timers, no rush.
On iPhone and iPad
Calm, quiet, yours.
A minimal interface that keeps out of the way: just the window, the palette, and as much time as you like.
