It is. I do. It is. My simple description of it is that its bridge with revealing cards for bidding and dynamic partnerships.

There is an iOS version of it - https://apps.apple.com/us/app/m%C3%BC/id351448383 (and it runs on my mini - https://imgur.com/a/eJsx4Wd )

And yea, the point values would be the problematic parts.

Incidentally, there's been a new issuing of the game: from the publisher - https://shop.czechgames.com/mu-more/ though it appears to be out of stock there, there is a reseller with the new version https://www.cardhaus.com/mu-more/

I'd also suggest Nyet ( https://boardgamegeek.com/boardgame/1107/nyet ) which is another odd deck count game (3x1, 1x[2...13]) x 4 suits. It was originally a ruleset for the Mü deck where you excluded rules from the next round ("no - not that rule" -> "Nyet")
