Relaxing color logic puzzles: a calm brain break, a fresh daily, fully offline.
Read full description
A relaxing logic puzzle for a calm brain break.
Fill a dark stained-glass window with light, one pane at a time. Every outlined region takes its colors once each, and matching colors may never touch, not even at a corner. That is all the rules there are. The rest is calm, satisfying reasoning.
No pressure
No lives to lose, no time limit, and nothing to buy to keep playing. Solve one puzzle on a break or a dozen on a quiet evening, and pick up right where you left off.
Learn by tapping
Your first window is a tiny 3x3 board that teaches you move by move. The palette only offers the colors that fit, so you learn by tapping, not reading.
Every puzzle is fair
All 4,000 puzzles have exactly one solution, reachable by logic alone. No guessing, ever. Six tiers, from Flicker to Nova, ramp by the reasoning each puzzle demands, not just by size.
A fresh daily
A new puzzle every day, easier early in the week and toughest on Saturday. Keep your streak alive.
Play your way
Pencil in notes with color, undo as far back as you like, and start over any time. Choose Assisted feedback or Classic, where nothing is said until you find the contradiction yourself.
Your own records
Your fastest time on every puzzle, a trophy when you beat it, and a progress page that stays on your device.
Color-blind friendly
Optional shapes on every color and an alternate palette for color vision differences, both one tap away. Light and dark mode, with the window always glowing at night.
Offline and quiet
No account, no sign-up, and never an ad while you solve. Stuck? Watch a short video and the game fills in one pane for you. One optional purchase removes the banners and the ads between puzzles for good.
