Play Stack Spire online
Stack Spire is a one-button tower-stacking arcade game: you are Pip, a crane operator building a neon spire into the night sky.
A block swings back and forth above the tower. Tap, click, or press Space to drop it — any overhang gets sliced off and tumbles away, and a complete miss costs one of your 3 hearts.
Land a block within a hair's breadth of center for a PERFECT: no slice, plus streak bonuses. Every 4th consecutive PERFECT regrows the tower wider. The swing gets faster every layer, and your best height is saved in your browser.
How tall can you build before the spire crumbles?
How to control Stack Spire

The swing gets faster with every layer. Your best height is saved in your browser.
Tips for a better run
Release a beat early at high swing speeds — the block drifts while falling.
Small corrections beat risky waits: PERFECTs are forgiving within a few pixels.
When the tower gets thin, play safe landings — a thin layer costs less than a lost heart.
Chain PERFECTs: every 4th straight one regrows the tower wider.
Alternate your eyes between the block edge and the tower edge to judge overhang.
Frequently asked questions
How do I play?
A block swings left and right above your tower. Click, tap, or press Space to drop it. Whatever hangs over the edge gets sliced off and falls away — land it dead-center for a PERFECT (no slice, streak bonus), and every 4th straight PERFECT regrows the tower wider. Miss the tower completely and you lose a heart (3 hearts).
Any strategy tips?
Watch the swing, not the tower. Drop when the block's center lines up with the tower's center — release a beat early at high speed, because the block keeps moving while it falls. PERFECTs are forgiving within a few pixels, so small corrections beat risky waits. When the tower gets thin, prioritize safe landings over streaks: one thin layer costs you far less than a lost heart.
Is Stack Spire a copy of a stacking game?
No. Stack Spire is fully original: Pip the crane operator, the neon spire, the swing-and-slice stacking rules, the regrow mechanic, and all code, art, and audio are original works. It takes the general tap-to-drop tower-stacking arcade genre as inspiration but references no existing games, films, or franchises.
