Drop the checkers and try to get 4 in a row vertically or horizontally or diagonally.
A new style tic tac toe with more space and for more players, you chose the rules of the game 3 or 4 or 5 … X and O in a row .
Fun and easy to use, just click on the shapes and move them around, any where you want.
