The aim of the game is to line up the same coloured gems in a row. Arrange three or more gems together to make them vanish. Line up four or more of the same coloured gems and create a 'Jewel Explosion' that destroys everything around it. Line up five gems and a 'Spectrum Gem' appears and explodes every gem of the same colour on the board. Create chains in the shape of the letters 'L' or 'T' and receive a 'Cross Gem' that explodes all gems in the same row and column.
