Center

Pieces advance towards the pond in the centre from all four sides, along lanes of 5 squares. Tap a row or column to shoot from the centre: you remove all consecutive pieces of your colour (the one the frog holds). When you hit a different colour, you swap colours. The arrow shows where the next piece will come in, and a lane flashes red when it is full: one more and the piece falls into the pond and you lose a life (that lane empties). The bomb clears the whole lane.
