STACK THE GLASS

How high will you go?

Tap the screen to drop glass plates on top of each other. Sounds simple — and it is, for the first ten plates. Then the swing gets faster, the plates get narrower, and you stack your way past the clouds into the night sky.

GAMEPLAY
Each plate floats back and forth above the stack. One tap drops it.

• Perfect timing → full width kept + combo bonus
• Slightly off → the overhang breaks off, next plate is narrower
• Full miss → everything shatters

LEVEL UP
Every 10 plates you level up and get a free boost, rotating through:
• Stabilizer — swing speed halved for 5 plates
• Widener — next plate is 50% wider
• Glue — more forgiving perfect window

No interruptions, no punishing mechanics. Just stack until you finally miss.

SIX GLASS TYPES
Every 10 plates the glass changes, with increasing score multipliers:
1× Float · 2× Frosted · 3× Colored · 4× Mirror · 5× Laminated safety · 6× Crystal

COMBOS
Every consecutive Perfect stacks your score multiplier. Miss a perfect and you're back to 1×.

ATMOSPHERE
From 10 meters up, the wind starts nudging your stack. The background shifts with altitude: dawn sky → clear day → dusk → starry night → stratosphere with aurora. Clouds, stars, and a rare Crystal Height achievement when your plate gets too narrow to hit.

CLEAN & QUIET
No ads. No in-app purchases. No accounts. Just stacking, with soft ambient music and real glass-like sounds. Your best stack is stored locally on your device.

SETTINGS
Music, sound effects and haptics can each be toggled independently.
