It is classic Color Lines or Lines 98. The game starts with a 9×9 board with three balls chosen out of seven different colours. In the Extra Color Lines, we extend size of board is 11*11. If the player does form such lines of at least six 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, four new balls are added, and the game continues until the board is full.
You can play Color Lines after hardly working to relax. Hope you like it!
