It is classic Color Lines. The game starts with a 9×9 board with three balls chosen out of seven different colours. If the player does form such lines of at least five balls of the same colour, the balls in those lines disappear, and he gains one turn, i.e. he can move another ball. If not, three new balls are added, and the game continues until the board is full. It's very small (only 1 Mb) Color Lines app ! It working on all devices with all screen resolution!
