Click on a group of 4 gems to rotate it one quarter turn clockwise.

Gems will disappear when they are in groups of 4 or more.

Watch out for the black stones (coal) which cannot be combined!
You can make them disappear by making them drop into the pipes at the bottom of the game window. Each pipe used gives you a bonus.

Keep an eye on the number of turns you have remaining, which is indicated on the left. Remember you can earn more turns by using the pipes!

LevelUp mode: Beat the stated score to advance to the next level.

Build groups of at least 4 gems to score points and set off chain reactions.

Get your own back on the sneaky individuals who slipped lumps of coal into your collection... Make them disappear down the pipes for vital bonuses.
