Connect 4

A CSS3 Game by CSS play

Red Wins!
Green Wins!
Click for New Game


Who says you cannot do logic with just CSS?

This uses the same principle as the previous Tic-Tac-Toe game but is more complex in its logic handling.

The game is for two players and plays as a standard Connect Four game keeping track of turns, disc positions and winning lines.

Green starts so click any of the green counters across the top of the playing area to drop it into the column below, the top line of counters will then turn red to show that it is now the red turn.

The counters will slide down the columns with animation in all browsers except IE9.

The logic for this is covered by just a handful of lines in the stylesheet and very little code.

Absolutely no javascript or any other scripting language.
