How to play
Tap anywhere on the screen or press space to drop the current sliding block. The block stops where it currently is; any portion that does not overlap the block beneath gets cut off. Perfect drops (full alignment) earn a small width bonus. Imperfect drops gradually narrow the tower until it becomes too thin to hit.

Editor review
Single-mechanic mobile-arcade games sit on a knife-edge between addictive and tedious. Stack Tower lands firmly on the addictive side because the core feedback loop — tap to drop, see the result, react to the new slider speed — rewards careful timing without ever feeling punitive about a missed beat.
The perfect-drop streak system is the design's clever wrinkle. Hitting full alignment on consecutive drops widens the block slightly, which functionally extends your run by giving you back margin you would otherwise lose. This creates a real strategic decision around aggressive vs conservative play: stop and breathe between drops to break a streak intentionally (when the slider speed is becoming unmanageable), or push the streak for the width recovery. Both are valid approaches depending on session state.
The colour palette shift every ten levels is a small but effective motivator. Reaching a new palette is a discrete milestone; the visual reward is satisfying enough that even players who would not normally chase a high score find themselves trying for the next colour. The daily seeded tower is a thoughtful additional layer for return play.
The one-tap input scheme makes the game genuinely platform-agnostic. The keyboard space-bar version on desktop feels identical to the mobile tap version; the gamepad button mapping is unchanged. For a casual arcade time-killer that earns its addiction honestly, Stack Tower is one of the better implementations.
