well I understand that /rolls enables and disables it,
but how do you toss the coin?
I cannot understand /NdF and /Nc I mean I tryed those could not use them

You can get coins when you press nc. It means that firstly you press /, then a number from 1 to 9, then then c. After that, press enter...

Thanks a lot for the explanation

It means that n is number and f are faces in dice case.

Thank you

For explanation of dices:
Type /NdF
F=face
N=number

the point of it i think is so as people can create custom games. like those who requested pig on the platform that's easily playable with the feature

This feature is pointless really.
The annoying thing when you're having an important conversation, and the master enable these dice
Everything gets bored.
