About this game

Gear Combination is a puzzle game where you connect gears to solve challenges.

How to play:
Select a quest and a spinning gear will appear in the upper-left corner. Your goal is to connect the multiple gears provided on the right to the main spinning gear to complete the quest. Gears can be placed freely in any position.

Features:
- 40 unique quests to choose from.
- Non-linear progression: Start from any quest you like.
- Replayability: Play completed quests as many times as you want.

Technical Note:
In this game, clockwise gear rotation is represented as positive speed, and counterclockwise rotation as negative speed.

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

Thank you for your thoughtful feedback. The current quests are simple tasks like connecting a certain number of gears, but we’re glad you enjoyed seeing the gears work as expected. Your ideas about deeper gear‑ratio challenges and more educational mechanics are great, and we’ll keep them in mind for future improvements. Thanks for playing!

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.

You can specify the magnification rate from the settings, so please try it.

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

For example, in Q1, a 16-tooth gear is rotating at 10 RPM at the root. When a 32-tooth gear is connected, its speed is displayed in red text as -5.0 RPM. This indicates that the speed has changed from 10 RPM to -5.0 RPM.

What’s new

We have updated the target SDK version to 36 to improve the app’s stability and security. You can continue to enjoy using the app as usual.
