Cogs HD is a groundbreaking puzzle game where players build increasingly complex machines using sliding tiles in 2D and 3D environments. With HD, iPad optimized visuals and all that extra screen size, Cogs HD gives fans of the original iPhone version and newcomers alike, a great new workbench to get inventive with.


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.


•Unlocked new contraptions by building contraptions against the clock with as few moves as possible.
•Mind bending multi-dimensional gameplay.
•Gorgeous steam-punk styled 3D visuals.
•11 initial pieces of malfunctioning machinery to get to grips with
•51 levels available
•Online leaderboards and achievements through Crystal!

Simply the Best!

This brain twister (actually slider) will make the wheels in your brain turn and then blow your mind like the many “Cogs & Steam Pipes” you have to slide into place to complete the some 5o plus puzzles. The graphics are eye candy and the ergonomics pajama comfortable for the fingers. For me, what sealed the deal to buy the full version was the so-called “Lite” gave me exactly what I needed to know what I was about to pay for and was free of clutter and ads that torque the fun out of any trial. I wish they would make it for the iPhone.

Definitely one of the best puzzle games out there and free of glitches. It's based on "The n-puzzle," (invented in 1879 and the basis for the Rubik’s Cube) was big in the 70‘s and commonly known as the "The 15 Puzzle" (and it's little brother "The 8 Puzzle"). It’s a classical problem for modeling algorithms involving heuristics (don’t let that scare you) and consists of sliding squares in a frame to solve the objective which is described before you start, giving you times to beat. The great part is, even after solving the puzzle, you can do it over to best your times making this game a real bang for the buck.

Bottom line... it's well worth the time and investment!!

Wow, Wow,Wow.

Recently, I purchased the game called Gears and having been enjoying it. This app however, is so terrific because the premise is the same, to connect the gears so they all move together in synchronization. The difference? It's dimensional. Therefore, you must find other gears on the other sides and get them to move along as well. The true and amazing challenge really comes in because you have to slide a tile to get the gear you want to place in position. This is a game that takes several different games we know and love and pulls them together and makes for one terrific and challenging puzzle. Love this. Buy it, no disappointment here. M.

One of the best!

I found myself buying the full app as soon as I finished the Lite version. It's really one of the best puzzle games for the iPad and it's worth every penny. Puzzles become more challenging as you progress and for me, the biggest temptation was to finish the game in one sitting at the expense of sleep because of the innovative puzzles. Graphics and UI are good. The game has been stable so far. And, Challenge Mode is certainly a welcome feature.

Cheers to the developers. I look forward to more puzzles in the future (the near future, hopefully).
