QuadroX is a program that really requires you to think outside the box. It's an interesting game that's roughly similar to one you might have played as a very young child. The object is to fill a square with pieces of different shapes. Once you're able to create a perfect square, you move on to an increasingly difficult level. It's a geometry teacher's dream. The full version of QuadroX covers three episodes with 30 levels each. This shareware version includes levels from the first episode. QuadroX is laughably easy when you first start playing, but the later levels are no joke and can be extremely challenging. As a rule, each level has one solution, and pieces can not overlap. You'll have to contend with some very oddly shaped pieces, which you rotate using your mouse. Pieces are dragged and dropped into the middle square, and are snapped to fit when placed inside. Top performances are recorded to a High Scores list. This program requires DirectX 6 or later.
