GameVortex writes: "Cogs is a great game. It features a unique concept, a nicely-crafted user interface and multiple modes that allow players to focus on their weaknesses and build their analytical thinking skills to proceed. On top of this, Lazy 8 Studios offers a level editing documentation, so players can create and share new puzzles to keep the game fresh.
Cogs is clearly not a game for everyone, as some people aren't interested in playing sliding-puzzle games at all, but there is a lot of fun and challenge to be had in Cogs. I highly recommend it to anyone who's looking for a good puzzle game to eat several hours of their time".
