The gears can be placed in any position.
There are 40 quests to choose from, and you can start from any of them. You can play the completed quests as many times as you want.

In this game, clockwise gear speed is represented as positive and counterclockwise gear speed as negative.

Oooh ok, i found the magnification scale. Now what I would really like in this app, is if there would be a customizable level, at which I could edit the size of the moving gear, or edit it's place, like a free mode. Also it would be a bit interesting if there would be a bit challenging way to play this game, like in example a torque indicator. That could be good.

I don't entirely understand each of the 'quests' after playing, as it is literally just "connect 2 gears, connect 3 gears, etc.." but it's cool to see the gears function as you would expect. I would like to see this app updated or another app created to go into better detail about the gear ratios, that has cool interesting ideas for utilizing gears in a fun, educational way, perhaps trying to get to a specified gear ratio or using other types of gears to move through a puzzle. Cheers, Josh

The simple and no fuss design was a plus, but I found that changing a gear up or down resulted in no change of rpm - results in an unfortunately unplayable game. Yes, the rpm was displayed as 6.80 - I tried different combinations of final gears, but the display didn't change
