Kiyosumi Highschool's mahjong club members sing "to the world of score 10,000 100,000 1,000,000" at the ending theme.
Now we begin with 100,000 aiming 300,000 to win.
If your score becomes zero or lower, the game ends.
If your score exceeds 300,000 you win.

1)一盃口 [Iipeikou] Two Identical Sequences “Pure Double Chow”
3)二盃口 [Ryanpeikou] Two Units of Two Identical Sequences
2)七対子 [Chiitoitsu] Seven Pairs:
each pair must be unique.
8888 will not be accepted as two pairs.

Note: this hand is not a pinfu
1)一盃口 [Iipeikou] Two Identical Sequences “Pure Double Chow”
667788
and
1)平和 (ピンフ) [Pinfu] No-points: All Sequences with waiting two way
78 waits either 6 or 9: this case 6 is winning as well as iipeikou
if you win with 9, no iipeikou but pinfu will be accepted.
What is this hand? chiitoitsu?
It's ok, no one will contradict:
In this case, you can name the highest to claim.
If you declair this hand as chiitoitsu, your score is 9 fan
[Tsumo(1) + Chiitoi(2) + Chin-itsu(6)]
But if you claim this as ryanpeikou(3),
223344 + 77889 with wining 9
also pinfu(1) will be added.
