Drag anywhere to turn the tower. Look up and down, or pinch / scroll to zoom.
Tap a block that matches the ball below. Connected blocks of that color pop together; the rest fall into place.
Clear the tower before your balls run out. Bigger groups mean more points and coins.
Rainbow matches any color. Quake clears the bottom layer. Buy both with coins you earn by playing.
Keyboard: ← → rotate · ↑ ↓ tilt · Space fire at the highlighted block · Q rainbow · E quake · P pause · M sound
