The goal is simple - remove all the gems from the board. In order to do this you have to slide gems from sides of the board. Tap on any gem located somewhere along the border of the board and a new gem will appear close to it, this new gem will begin to slide towards the opposite side of the board. It will slide until it hits the board's border or another gem that has a neighbour gem along the line of movement of the sliding gem. If that gem doesn't have such neighbour the sliding gem will push it until it will hit the border of the board or some gem. If sliding gem joins a group of three or more gems of the same type - all these gems disappear. Looks simple, but... If you fail to remove any gems with your move the number attempts for that round is counted down and when it goes down to zero some new gems will appear on the board. There can be no draw in this game, either you remove all the gems from the board or they fill all the board. If you are conf with rules of the game just watch the Demo, and everything should become clear.
