Stack Tower

Stack Tower (also known simply as Stack) is a minimalist yet deeply satisfying tower-building puzzle game. The concept is clean: moving blocks slide back and forth automatically, and you tap or click to drop each one onto the stack below. Any part of the block that overhangs the previous layer gets cut off, shrinking your block. Your tower grows taller with each perfectly placed piece, but one careless tap can reduce your block to a sliver and end your run. Play Stack Tower free online at MSGameOnline — no download needed.

Each round the swinging block moves at a consistent speed, but as your tower grows the blocks can come from different angles and subtle size reductions accumulate. A perfectly centered tap leaves your block full-sized; an off-center tap trims the overhanging portion away permanently. After a few imperfect placements your stacking surface can become razor-thin, making subsequent drops even more nerve-wracking. The tension builds beautifully with each floor added.

Patience and timing are the entire game. Resist the urge to tap early, and train yourself to wait for the block's sweet spot directly above the stack. A useful trick is to focus not on the moving block itself but on its shadow or the edge of the stationary block — this gives you a fixed reference point. Perfect stacks feel enormously satisfying, and near-misses that leave a paper-thin block keep you coming back for redemption.
