I do not like sliding puzzle games. I find them boring, tedious, and ultimately frustrating. Thankfully, some developers seem to feel the same way and are actually making attempts at turning the genre into something fun and compelling. The developers of COGS have succeeded in a big way. Each puzzle is different, and they managed to infuse the third dimension into the game play in such a way that it not only doesn’t destroy the premise, but actually enhances it. Add to that some nifty contraptions rendered in stylish graphics and you have yourself a winner with COGS. If you’ve been avoiding the slider puzzle genre as it’s permeated the App Store, now would be a good time to try one out. Just don’t get your hopes up that any other slider puzzle will come close to this one in terms of enjoyment.
