Hello found the option "play with mugging, this is in cribbage it is not in the game instructions. was trying to read but players left before I could locate what is mugging in cribbage?

The mugging is a variation of cribbage. If it is enabled and you make a mistake, the points more or less calculated are given to the opponents, like it was before. Otherwise your points aren't lost or gained. It is useful for beginners, for example. That was posted in the news page, lol...
