Stack Tower: Block Builder

The simplest, most addictive tower-stacking game — all timing, one tap.
A block slides left and right. Tap to drop it onto the stack below. Whatever hangs over the edge gets sliced off, so every block gets narrower. Miss completely and the tower topples. How high can you build?
WHY YOU'LL LOVE IT
• One rule — tap to stack. Learn in 5 seconds, play forever.
• One hand, portrait mode. Perfect for commutes and quick breaks.
• Blocks speed up as you climb — your focus is the only limit.
• Satisfying shatter effects and screen shake when it all comes down.
PERFECT COMBO
Land a block dead-center for a PERFECT — and it grows back a little wider. Chain perfects to recover a narrowing tower and unlock a path even higher. Reviving a razor-thin block with a clean PERFECT is the heart of the game.
A COLOR FOR EVERY FLOOR
The blocks shift smoothly through the rainbow as you rise — red, orange, yellow, green, cyan, purple. Your height becomes a glowing ribbon of color against a minimal dusk sky.
BEAT YOUR BEST
Your floor count is your score. Set a new record and a NEW! badge flashes — your best is saved on your device. Beat yesterday's run, and your friends'.
REVIVE WITH AN AD
A mistake isn't the end. Watch a rewarded ad to revive on the spot and keep your tower going. Push that single-run record further.

No tutorials, no sign-up, no waiting. Open and tap. Plays offline, even in airplane mode.
