"Pathological is a puzzle game consisting of marbles that roll along paths, and interact along the way with various devices and gadgets. The object of each level is to "complete" all of the wheels on the board. To complete a wheel, catch four marbles of matching color in the same wheel. The marbles will vanish, and the wheel will turn dark to indicate that it has been completed. Note that this is only the usual way of completing a wheel. The exceptional cases are described in the section on Triggers and Stoplights. To rotate a wheel, click the right mouse button on the wheel. To eject a marble from a wheel, click the left mouse button on the marble. When the game begins, you are assigned a total of three lives. Your spare lives are depicted by small red marbles at the top of the screen. An extra life is awarded every 5000 points. A maximum of ten spare lives is enforced.... Various board elements such as teleporters, switches, filters, etc., make the game interesting and challenging. New levels can be created using your favorite text editor."

If you have played Rainbow Arts' Logical and/or like brainteasers in general, you will love Pathological. It's the same addictive puzzle gameplay, enhanced with SVGA graphics, more special items, and the ability to create your own levels. The game is as challenging as I remember, and as insanely addictive. Two thumbs up, way up!
