|Some tiles have double marble tablets under them. Make two matches on such tablets to destroy them.
|Ice tablets freeze some parts of the board, so you can’t match those tiles. Match three or more tiles above the ice tablet to unfreeze them.
|Some tiles are locked by a chain or a double chain which prevents them from moving. Break chains by making a match with the tile under it.
|Some levels have Skulls. Avoid matching Skull tiles as they add extra marble tablets on the board.
