Stack blocks perfectly to build the tallest tower!
Tap to drop blocks. Align them to build higher!
Tap or click the canvas to drop the swinging block. Try to align it perfectly with the previous block. The overlapping area becomes the next block's width. Stack as many blocks as you can!
If you drop a block very close to perfect alignment (within a few pixels), you'll see a "Perfect!" message and the block will keep its full width instead of shrinking. This helps you build taller towers!
The game ends when your block becomes too narrow (less than 10 pixels wide) or when you miss the previous block entirely. Your score is the number of blocks you successfully stacked.
Tower Builder is a precision-based stacking game where you build a tower by dropping blocks from a swinging crane. The challenge is to align each block as perfectly as possible with the one below it. Misaligned blocks get cut off, making each successive block narrower. Perfect drops reward you by keeping the full width, allowing you to build taller towers.
The game progressively gets faster every 5 blocks, testing your reaction time and precision. Your personal best is saved locally, so you can always try to beat your high score. The colorful blocks and smooth camera panning make for a satisfying gameplay experience.
