If the only open cells are on the opposing wall or in a sequence stemming from an open cell on the opposing wall then you will have to move in that direction rather than away from it.To move in any particular direction you need at least one open cell to be on the wall in the direction you are moving or somewhere other than the opposing wall.By manipulating the order stones merge and moving them around the playing field you can slowly move stones of the same value that are not near one another into adjacent placements.Stones always move as far as they can in the direction of your movement until they run into the edge of the screen or another stone.If you have 4 consecutive stones of the same value then all 4 will merge into 2 stones in the 2 spots furthest along in the direction of the move.If you have 3 consecutive stones of the same value the the first 2 stones in the direction of the move will merge together.When 2 adjacent cells have the same value if you press the arrow key to slide the tiles toward one another then the two tiles will merge into a single tile of double the value in the direction of the slide.The game shows your current score and all time top score in the upper right corner.Swipe the screen with your finger to move the tiles.Use the arrow keys on your keyboard to move the tiles around.The game starts with you in active play.Move the tiles around the 4 by 4 grid to merge tiles of the same numerical value into a tile with double the value.
