Reaches 1st dan rank in MFC DS in a single match, through lots and lots of luck manipulation. In theory this can be done in 3 hands instead of 4 but that would require luck-manipulating a roughly 1 in 800 miracle (oya yakuman + baiman or 2x oya sanbaiman in the first two hands, both requiring that no AI player declares riichi in the first two hands) and the tile draw sequence is fixed once the hand starts. The game doesn't pick up any entropy from individual inputs or idle frames as far as I can tell. The AI appears to be the only thing that seems to advance the seed during a hand, and even then it can't affect the tile draws until the next hand.

To hit 1st dan in a single game, you must win a total of 80000 points across hands (plus another 100 points for every 200 points you lose from losing hands, rounded up to the nearest 100). The 300-point bonuses from honba count towards this total, but not the 1000-point riichi antes or the 5000-point bonus for coming first. Meanwhile, the scoring is zero-sum and the match ends if any player goes broke, and the 3 AI opponents start with 25000 each, so I need to get them close to 0 without going under then send at least one of them deep into the negative in one blow.
