Cogs is a ground-breaking puzzle game where players build increasingly complex machines using sliding tiles in 2D and 3D environments. The basic app comes with 10 puzzles and three gameplay modes for a total of 30 unique challenges. Puzzle enthusiasts can buy up to four additional puzzle packs, each with another 10 puzzles, totalling more than 10 hours of mind-bending gameplay. This award-winning game is perfect for puzzle fans of any age and ability!

“It is awesome.” – TouchArcade
"One of the highest quality puzzle games we've seen." – PocketGamer
“The visual design and imagination of the game are stunning, with great attention to detail, and the sound effects are downright enticing.” – Adrenaline Vault
“If a sliding puzzle was a wheel, consider it re-invented!” – TouchGen
“A masterpiece visually, as well with the actual gameplay.” – AppAdvice

Starting with simple puzzles, players are introduced to the widgets that are used to build machines — gears, pipes, balloons, chimes, hammers, wheels, props, and more.

If you finish a puzzle in Inventor Mode, it will be unlocked here. This time, it will take fewer moves to reach a solution, but you only have 30 seconds to find it.

Take your time and plan ahead. Every click counts when you only get ten moves to find a solution.

What's New in Version 1.5.1

Cogs now looks great on every device, including support for retina displays! Much faster startup. Now tracking achievements with Game Center.

Customer Reviews

It's back!

I used to love this game! So glad to see it updated for new devices; just replayed a few levels and it's like rediscovering an old friend.

Doesn't work

The game doesn't even open. Period. Only app I've ever had that simply won't run. Very disappointing, since it's not free. Looks like it'd be a pretty cool game.
