Geek writes: "Having played both the preview code and the final Cogs release, I can confess it's been keeping me up over the past three weeks. This sliding puzzler is unlike any other brain challenge game I've played thus far. First of all, Cogs' beautiful graphics and Lego-inspired steampunk design is a sight for sore eyes. The art style oozes from every facet of the game, from analog widgets and the odometer-style counters to the revolving puzzle descriptions and the massive iris in the background that opens to reveal each new puzzle. Third-gen iPod touch and iPhone 3GS owners can take advantage of their speedier hardware by cranking up the visuals in the options menu."
