## What is 1Stack?

Tap at the right moment, stack each moving block, and build the tallest tower you can.

1Stack is a focused one-hand arcade game for quick runs. Precise placements preserve the tower, perfect drops build combos, and every miss ends the run.

Features:
• Simple one-tap controls
• Classic mode and Daily Tower: the same tower for everyone each day, with a day streak
• The sky changes every 10 floors, from a green meadow up to space
• Keep perfects going and your block grows back
• Daily, weekly, country, and world rankings
• Perfect-drop combos and increasing difficulty
• Local best score with offline gameplay
• Korean, English, Japanese, and Spanish
• Kid-safe ads only after a run ends; no banners and no ads during play

An internet connection is required for online rankings. Core gameplay and the local best score remain available offline.
