Modulo is a cheerful, original puzzle game based on interconnected spinning gears. Hands down, it’s one of the best puzzle games on my iPod—easy to learn, and fun to play.

After some time with the game, it seems like a good concept that was delivered in a completely wrong way. I couldn’t encourage anyone to purchase this game at this stage of its development. There are plenty of other really fun games out there that were made with the iPhone platform in mind.

GudeBalls is a puzzle game involving spinning plates and marbles. It’s a quirky, odd game, and pretty entertaining, even if it lacks immense replay value.
