Your fingers are what you use to do the cutting on Apple's devices, but here you've got the stylus. Interestingly, though, I think playing this game on a DSi or 3DS actually improves it over its original versions in one key way – accuracy.

The price is also steeper here, though paying $4.99 for a game you could get for $0.99 elsewhere certainly isn't the worst valuation discrepancy we've seen with DSiWare. As with other games that have made Nintendo systems their second stop after debuting with Apple, the visuals take a hit here – DSi screen resolution can't compare with the iPhone's beautiful Retina display or the iPad's HD screen. There are some drawbacks to playing Cut the Rope on DSiWare, of course. Later levels aren't unlocked unless you earn enough stars in earlier stages, and the truly hardcore will want to try scoring all three available stars in each of the game's 125 different levels. You also have to try to collect stars along the way, by sending the candy on a path to collide with them inside the box before finally landing inside Om Nom's mouth. What's more, feeding isn't your only goal.

The challenge factor ramps up at a satisfying pace, though, as later levels integrate more and more interactive objects to alter the simple premise in some truly complex ways – multiple ropes, floating bubbles, energy barriers and even an absence of gravity all force you to figure out just how you're going to safely deliver each treat to the creature. When the game first begins, the puzzles you're challenged with are all easily solved – one or two swipes across the screen are all that's needed to accomplish the goal of feeding the happy monster.
