Inventor Mode: 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.

Time Challenge Mode: 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.

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

Can’t access puzzles if you’re not super speedy

This game requires you to solve the puzzles very quickly and with a minimum of moves, otherwise it won’t unlock most of the puzzles. I have to take my time working through challenging puzzles.. . But I paid for the whole game, and it’s irritating that I can’t access most of the puzzles I paid for. They should at least warn you about this in the description befiore purchase.

Not working, still, on Yosemite

I've played the game on my iPad, but trying to run it on my new iMac and OS X Yosemite is totally bizarre. Strange geometric shards instead of gears/cogs, illegible and dark. I suggest waiting until an update is announced that fixes the graphics bugs!
