Power-ups appear on the game field once you match four or more pieces. These power-ups are available in the game right now:

1. Rockets clear all tiles in a row or a column (depending on which direction they're pointed in). You can get them by matching four pieces in a line.

2. Bombs are activated by a double tap and remove a significant number of pieces. You can get them by matching five or six pieces in an L or T formation.

3. Paper Planes remove one random piece on the field: they tend to hit locked elements or level goals first. When taking off, Paper Planes also destroy the neighboring pieces. You can get them by matching four pieces of the same type in a square.

4. Rainbow Balls remove all the pieces of the same type from the field. You can get them by matching five pieces in a line.
