Tap the gem ad the the blak tile to move the gem.

Move the Gems to the blank spaces in order to create a horizontal or vertical row of 5 identical items. To move just tap the item and then tap the location you want it to move. If there is any open path between the item and its destination, it would travel to the new place. Each time when you move a gem and if no match happens, 3 new gems will be added to the board. Don't let the board crowded or it may fill all the places and your spell will be ended.
