How to play Tower Stack

Tower Stack is a precision timing puzzler. A neon block swings left and right above your tower — press to drop it onto the stack. Any part hanging over the edge gets trimmed off and tumbles away, so each imperfect drop makes the tower narrower. Stack block upon block and climb as high as you can; the swing gets faster every level. A block that misses the tower entirely ends the run. The camera follows your tower skyward, so there is no ceiling — only your timing decides how tall it grows.

Controls

Press Space or click / tap anywhere on the game canvas to drop the swinging block. ▶ Start Game begins a new tower and ↺ Restart starts over. Timing is everything: watch the block's rhythm for a swing or two before committing.

Tips & strategy

Perfect drops — landing within a few pixels of the block below — keep your full width, so patience pays off hugely in the early slow game. As the tower narrows, shift from chasing perfects to simply surviving: a small trim beats a total miss. The swing follows a smooth rhythm, so count the beat ("one-two-drop") rather than reacting to what you see — reaction lag makes you late if you wait for the visual. On very narrow blocks, aim for the platform's center and accept tiny trims. Never drop while the block is accelerating across the edge; wait for the turnaround moment when it briefly slows.

Scoring

Every landed block scores 1 point of height, and perfect drops keep your tower wide for future levels. Your tallest tower is saved in your browser as your best. One complete miss ends the run — no extra lives, no time limit, just you against the swing.
