HOW IT WORKS

— FOUR THINGS TO KNOW —
01

Watch the Arm

A robot arm holds a block and swings it across the top of the screen.

02

Drop the Block

Tap or press SPACE to release. The block falls onto the stack below.

03

Aim Perfect

Land it dead-center for a bonus. Misalign and the off-center part falls off.

04

Build Combos

Multiple perfects stack a multiplier. Miss the stack entirely — game over.
