Tower Stack: Block Builder

Build a tower one moving block at a time. Tap to place each block on the stack. A perfect placement preserves the block's full width. If part of a block extends beyond the edge, the excess is cut away, so the next placement is harder. A complete miss ends the run immediately unless you use an extra life that you earned.

POWER-UPS
- Slow Motion slows block movement for 5 seconds.
- Wider expands the current or next active block, up to its initial size.
- +3 inserts three perfectly placed blocks.

Chain accurate placements to build combos. Combos increase your score and can trigger stronger effects. Try to beat your personal best and build higher in every run.

FEATURES
- Simple one-tap controls
- Short rounds designed for replay

- Earned extra lives can save a run after a complete miss
- Clean visual style
