Losing My Marbles is a mod that adds track pieces and marbles to Minecraft so you can build your very own marble run.
Each marble has full physics simulation, powered by Jolt Physics. They roll and bounce around like real ones!
Losing My Marbles currently features 11 unique track pieces and 30 different marble types. If you get bored of the marbles, don't worry! Marble types are fully datadriven, and you can make your own with a datapack.
