Rotate
Tap Rotate, pick a piece, then tap Rotate again. Every tap turns it 90° and uses 1 rotate. It always stays aligned to the grid.
Bomb
Drag the bomb across the board. Touching blocks of the same color light up to show what will go. Release to blast them. A lone block does nothing and the bomb is not spent.
Undo
Bad move? Undo brings your last piece back, along with the points of that move.
