History:

I first read about Quad in the pages of Scientific American Volume 274 Number 3, March 1996. The original games rules and concept were invented by G. Keith Still. Several modification have been made to the rules during that time to make the game play better suited to a computer player with limited resources but the concept remains roughly the same. The computer player uses a standard Min-Max search which is very shallow, this keeps Quad running at a brisk pace. A heuristic is chosen at random from a list each time you visit the site and the heuristic's name is displayed in the text area.

Objective:

The objective of quad is to place one of your pieces at each of the four corners of a square. When you have done this you have made a Quad and you get 1 point. The person who has the highest score that is above 16 wins. In the event of a tie you always win. A Quad can be in any orientation and of any size. and are examples of Quads.

The Rules:

You and your opponent both start each game with as many pieces as you need and only 7 Quazars . Each turn you may place as many of your Quazars as you want, but remember that you only get 7 for the whole game. Your turn ends when you place down a piece, so always place down your Quazars first. To place down a either a piece or a Quazar you just click the square you want it to appear in. You can switch between your clicks placing Quazars or pieces by clicking on the button labeled . The game displays what you are dropping and how many Quazars you have left on the bottom of your left hand side of the screen . Quazars are used to block the opponents moves so that it can not make Quads.
