Drop swinging blocks and build the tallest, neatest tower you can. Nail the alignment for a perfect stack; miss it and your tower trims down.
A block swings from a crane across the top of the screen. Time your drop onto the stack just right — perfect alignment keeps the block full width, while a miss shaves off the overhang and shrinks your base. Keep stacking and climb as high as you can.
Click the mouse, press Space / Up / Down, or tap on touch to drop the block.
