My mom just scored 140,600 points in a single game. The hand she won with, a double yakuman as dealer, hit every player more then their entire starting value, so it was an instant knockout of two players and I was left with only a couple thousand points, ending the game. To put things into perspective, getting a normal yakuman has only happened around 5-6 or so times for me in a couple of years, and that would have only gotten me 32,000 points each unless I happened to be dealer. Getting a yakuman basically means you win and she got that X4. :golfclap
