Move The Dots app for iPhone and iPad

Move the Dots and get the scores. How many scores can you get?

Game rules:

The game starts with a 7×9 board with some Dots chosen out fives different colors. The player can move one Dot per turn, and the player may only move a Dot to a particular place if there is a path (linked set of vertical and horizontal empty cells) between the current position of the Dot and the desired destination. The goal is to remove Dots by forming lines (horizontal, vertical or diagonal) of at least four Dots of the same color. If the player does form such lines of at least four Dots of the same color, the Dots in those lines disappear.More Dots are added, and the game continues until the board is full.
