Touch the controls to tip the board and make all remaining blocks roll one space in that direction.
A block won't move, however, if there is a wall or another block in its way.
You complete the board by sinking all the blocks.
However, you're not allowed to sink more than one block at a time, and you can't sink a block in a hole that's already been filled by another.
It's dicey, but you can do it!
