Roll Playing Machine
Note: make sure to go fullscreen in the Love2D web player, and if the UI looks garbled try re-toggling fullscreen in settings! If a gear *should* connect but doesn't, try removing and placing it again! If you make a level you think is worth going into the game, send me a video on X!
Connect gears from a source motor to a receiver!
Control the signal - smaller gears increase the signal, larger gears shrink it! Modifiers, obstacles, and deeper mechanics like rotation and torque await! How many possible solutions are there? Improve score by using fewer gears!
Use the level editor to build your own puzzles!
Built for the *very serious* Juniper Dev Jam, June 2026. Theme - Spin to Win!

Really clever puzzle game! I like how the simple idea of connecting gears gradually becomes more complex through different gear sizes, obstacles, rotation, and torque.
The presentation is clean, and the visual feedback makes it easy to understand how the signal changes while experimenting with different solutions. I also really like that you included a level editor. That adds a lot of replay value.
I did have trouble launching the game in Chrome because I got this JavaScript error:
Uncaught NotFoundError: Failed to execute 'transaction' on 'IDBDatabase': One of the specified object stores was not found.
However, when I tried the game in Edge, it worked without any issues.
Great job overall! The concept fits the jam theme very well and has a lot of potential for even more levels and mechanics.
A very polished game,
I really enjoyed it, simple yet so good ^^".
Very cool game.
Torque as a mechanic feels forgettable as it's possible to play the whole game only looking at RPM, leading the player to be able to not understand the relationship between the two as they should.
You can make some levels only require Torque at the end instead of RPM+Torque because RPM effetively serves as a tip. The difficulty stays exactly the same assuming people are thinking with gears properly.
Thank you, I love the idea of having torque replace RPM as a requirement for some puzzles to teach it properly - will definitely do so if I expand this further.
Easy to understand but very fun and intricate puzzles. very enjoyable.
Oh, funny enough I already played this one! I like it, it's easy to understand and pretty fun. It is very very easy though...
Thanks for playing! Yes, I did think the puzzles are on the easy side, however quite a few people haven't been able to complete all 20. So I figured it's an alright balance for this jam and could potentially be expanded into more complex puzzles later.
Would love to see any puzzles you can create in the editor! (Apologies for the janky interface)
This game is so awesome, and I have no idea how you pulled this off in a week!
Thanks for playing!
It's fun, and the fact you added a level editor + 20 levels in a week is crazy! It seems a little unclear sometimes, so maybe you could give some more context or an explanation of how everything works on each level. Overall, it's really good though, so keep it up!
Thanks for trying it out!
my head hurts 👍
took me a bit to understand everything that was going on, didn't see the instructions at the top of the screen at first.
the fact that you got a level editor in there is really cool, keep up the good work !
Thank you for trying it out :)
We really enjoyed this game! The fact that you made a level editor is crazy. It gets really hard and mind buggling, but thats a well polished game, congrats !
Thank you so much! The level editor is what I used to build the puzzles so I thought I'd leave it in haha.
