4 Play (1993)

Let's make it simple : 4 Play is a Windows 3 version of the classic Connect 4 game.

Start by choosing the type of game being played (human vs computer, human vs human, or computer vs computer) then who goes first. You can even give names to the players, or use default ones (red for human, yellow for computer). You can also set in the "Options" menu the computer search depth, to any value from 3 to 9. The default value is 4. Then the game can start : to make a "move", simply click on the slot you want to place a piece in.

The game is shareware but not crippled at all.
