Transparent shapes can only remove matching symbols, while red shapes remove any combination of tiles. Some levels have obstacles like pillars and stones that must be removed by making matches next to them. Tiles with steel or wood background require multiple matches to be removed.
A shop selling power-ups appears between the levels. These items can be purchased with coins that appear on the grid and the tray. Explosives destroy several tiles at once, the lightning bolt zaps random symbols, the rocket breaks a whole column of tiles and the magnet creates a vortex that removes several symbols.
