Stack — Tower Block Puzzle

Build the tallest tower you can, one block at a time.

Stack is a beautifully minimal one-tap game about timing and nerve. A block slides across the screen. Tap to drop it. Line it up perfectly and the tower grows — miss, and the overhang shears off and tumbles away. Every block makes the next one harder.

HOW TO PLAY
• Tap anywhere to drop the moving block
• Land it flush on the block below
• Miss, and the overhang is sliced clean off
• The tower narrows and speeds up as you climb

PERFECT DROPS AND COMBOS
Land a block dead centre and it snaps into place instead of shrinking. Chain perfect drops to build a combo — and every sixth perfect grows your block back, giving you room to breathe. Precision pays.

CHOOSE YOUR SPEED
Four tempos, from Relaxed to Insane. A calm wind-down or a white-knuckle reflex test, depending on your mood.

SIX COLOUR THEMES
Aurora, Ember and Mono are yours from the start. Unlock Candy, Neon and Forest with coins you earn in game. Neon and Forest are deep, glowing dark themes that look gorgeous at night.

DAILY MISSIONS
Three fresh challenges every day — reach a target height, land perfect drops, hit a big combo, play a few rounds. Clear them for coins, and spend those coins on new themes.
