Chillingo has released Cogs, a unique new puzzle game where players are challenged to build complex machines in two- and three-dimensional environments by sliding tiles. The game includes multiple game play modes including an exploratory free-play inventor mode and time- and move-limited challenge modes. New puzzles are unlocked as players complete challenges. Cogs provides a visually attractive design and an online leaderboard for users to share their high scores. A basic version of Cogs with 10 puzzles and three game play modes is available on the App Store for $1. Four additional add-on puzzle packs are available for $1 each via In-App Purchases with each puzzle pack containing 10 additional puzzles.
