I lack any ability to post regularly lol.
Anyways, here is an event whose rules I'm not going to explain since it's so obvious.
If you want to use it, then credit me and that's it.
Ok, bye.
Edit: in order to add new contestants, both the tagger (I think is that how is called?) and the tagged marbles need a unique "materialName" that's is different from the rest of the taggers and tagged marble (also the new tagger and tagged marbles need to have the same materialName, else it will not work). Idk why I didn't mention this earlier...
