In this fun puzzler that's simple in concept but hard to master, the goal in Logical is to arrange the order of the colored balls to match the required pattern on the left of the screen (e.g.4 yellow in a row) by rotating the two rails. Both puzzle savvy and reflexes are needed as the top rail quickly fills with colored balls which come faster with each new level. It's a lot of fun, and will provide many hours of intensive brain and reflex exercise. Replayability is limited due to a lack of random levels, but the included (albeit somewhat difficult to use) level editor makes up for this deficiency, and dozens of devious levels will keep you up many a night. Two thumbs up!
