About GLASS
GLASS is a calm stained-glass logic puzzle about color, balance and quiet focus.
Fill each window with four colors and follow one clear rule: matching colors can't touch. Every pane you color narrows what can go next to it, until the finished design locks into place and the whole window lights up.
What begins simply becomes absorbing. One choice changes the next, and an adaptive score builds layer by layer as you solve, so the music finishes when the window does. There are no timers and no rush, just a dark, gallery-like backdrop that lets every finished window glow.
Features
- Four-color stained-glass logic puzzles with one rule: matching colors can't touch
- Real-time glass: textured panes, light shafts and a glow that floods in as you solve
- Adaptive music that grows layer by layer with each window
- Relaxed play with no timers, plus hints when you want them
- 12 puzzles included, with 20 optional packs of 12 more
- Cosmetic palette packs for a fresh look, with no gameplay changes
- Made for iPhone, iPad and iPhone Duo, with a palette that moves to the side on the Duo's screens
- No ads and no accounts

GLASS turns the four-color theorem into a calm stained-glass puzzle for iPhone and iPad
Fill each window with four colors. Matching colors can't touch. Adaptive music grows as the light comes through.
Fountain Interactive today announced GLASS, a calm stained-glass logic puzzle for iPhone, iPad and iPhone Duo. Each window is a pattern of panes to fill with four colors, under one rule: panes that touch can't share a color.
Every placement narrows the possibilities around it, so the puzzle tightens as the design comes together. When the last pane is in, the window lights up against a dark, gallery-like backdrop. An adaptive score builds alongside, adding a layer with each step, so the music finishes when the window does.
GLASS is built for relaxed play, with no timers and no ads. Twelve puzzles are included for free. Twenty optional packs add twelve more windows each, and palette packs change the look of the glass without changing the game.
Availability. GLASS is coming soon to the App Store (https://apps.apple.com/app/id6759615170), free to download with optional in-app purchases.
