Stack

Tap to build higher

Stack is a minimalist arcade game from Ketchapp in which you place moving blocks on top of one another. Tap when a block lines up with the tower; a poor alignment leaves a smaller platform for the next move. The aim is simple: keep the tower growing for as long as your timing allows.

A small game built around timing

There are no complicated controls to learn. Each round centres on watching the block’s movement, judging the right moment, and tapping once. That makes Stack a good fit for short breaks, one-handed play, or anyone who prefers an arcade challenge with a clear rule and quick restarts.

The presentation stays restrained while you play. The tower uses a clean, geometric style, and the colours shift as the run continues. This gives progress a visible sense of change without adding menus, equipment, or a long list of objectives to manage.

What to expect from the loop

• Easy to start: the central action is a single tap.
• Precision matters: placing a block near the edge reduces the usable surface above it.
• Repeatable runs: a mistake ends the attempt, making another try immediate and familiar.
• Limited variety: the appeal comes from improving timing rather than exploring different modes or a large set of mechanics.

Ratings and fit

Stack sits in the Arcade category and has a 3.9582715 rating from 445,376 reviews, with 50,000,000+ installs. Those figures point to a broadly recognised pick for casual arcade players. Choose it if you want a focused test of rhythm and accuracy; look elsewhere if you need a story, extensive progression, or more variety between sessions.
