Candy Lines

Candy Lines starts with a 9×9 board with fives candies chosen out of seven different colors. The player can move one candy per turn, and the player may only move a candy to a particular place if there is a path (linked set of vertical and horizontal empty cells) between the current position of the candy and the desired destination. The goal is to remove candies by forming lines (horizontal, vertical or diagonal) of at least five candies of the same color. If the player does form such lines of at least five candies of the same color, the candies in those lines disappear, and he gains one turn, i.e. he can move another candy. If not, three new candies are added, and the game continues until the board is full.
