Can you master the Grid?
Easy to play: choose to play against the A.I. or a friend, select the level difficulty and tap on your first grey cell. The line of cells in all four directions will take the players colour and when all the surrounding cells are claimed, a point is given. Take away points from your opponent by tapping cells around their claimed points. Black squares are unplayable until every square around them is taken and can be pivotal towards the end of the level.
