Welcome in this strategy game. You play against your computer on a board of 15 x 15 cells. The computer has the black balls, you have the white ones. You play one after the other. Your objective is to built up a line of 5 balls of your own colour. To put a ball on the board, click on the cell you want. Since you play against a computer, to be rapid is not the solution, but rather to think. Good luck!
