Two players take turns putting in chips and the first person to get four in a row, whether up and down, side to side, or diagonal, wins the game. Use the arrow keys (or WSAD) to move from side to side. Press the down arrow or space to drop the circles. Press 'R' to reset the game.
I hope you like it! When the game is over and it says red or yellow wins, press that or the "R" key on your device to play again or restart.
