Rules of the game: Connect-4.

This game is very simple. You must align 4 pawns of your color horizontally, vertically, or diagonally. The pawns are attracted by gravity, and you can place them on top of others. The game board is 6x7, and the first player to align 4 pawns wins.

To play, just click the area where to place your pawn.

Remember you can set the clock parameters in the game options.
