You are Red and the computer is Blue. Click on two dots that are next to each other to make a red line. The computer does the same and that makes a blue line. It takes four lines to make one square and if you completed the square, it turns red and if the computer did it, it turns blue. Whoever completes the most squares, wins (there are 49 squares so there can't be a tie) .
k thank u but i dont always join 4 lines sometime only 1 of them i did and the others were the computer. and the computer got like two long vetical lines and i clicked to join the top ones up and all of the vertical line joined and made blue squares .!
