One piece in every row, column and zone.
Glowpane is a logic puzzle for iPhone and iPad. Each board is split into coloured zones. Place exactly one piece in every row, every column and every zone, and never let two pieces touch, not even at the corners. Every board has exactly one solution.
100 levels in 10 windows
Ten chapters, from Ruby Window to Fuchsia Window, with ten carefully tuned levels each. Boards grow from 5×5 to 10×10, and levels 30, 40 and every tenth level up to 100 are marked hard.
Stars for a clean hand
Earn up to three stars on each level, 300 in all. Stars count only mistakes, never time, so you can think as long as you like.
A new board every day
At midnight on your phone's clock, a fresh 10×10 daily puzzle appears. Everyone gets the same board on the same date. Keep your streak going, with shields to cover a missed day.
Help that teaches
Level 1 walks you through the rules. From level 6, each round has 3 hints and 1 reveal. A hint never places a piece for you: it shows the next thing you could work out.
Quiet and private
No account, no ads, no tracking, and no internet connection needed. Version 1.0 is free, with no in-app purchases. Your progress stays on your device.
