Confused now, hasn't this been dumped already? (#1265) Or has it finally been released outside of Germany? (I was testing it for my Mum but couldn't find it for sale anywhere except on German sites. Doesn't make much difference because the tiles are too small for her to see anyway but I'm sure it's the same game).
Except it isn't, it is Shanghai - where you remove the pieces.
Judging by the screenshots, it has always been Shanghai, and not Mahjongg, unless there's another game mode that *no one* has mentioned or taken screenshots of. #0797 is a real game, this is recycled crap.
