So close but not quite, Jo'on

The tanuki tail on the bowl on the last panel.

Well played Mamizou, well played.

Now the big question: can Kyouko be chastised by the Myouren Temple for gambling if there was no real element of chance to begin with?

So it was still Mamizou's prank, but not with dice!

wouldn't jo'on notice the inconsistencies with the bowl though?

I guess triples are also a good roll?

Yes. Basically:
6-6-6 = a triple, instant win
2-1-2 = pair plus the odd die as the point value, 1 is instant loss in this case, 6 is instant win, anything in between is good for banker because player must roll either instant win or higher point to beat the banker.
1-1-1 = a triple, instant win
1-3-5 = indeterminate outcome, must reroll.

And when Kyouko threw the dice out of the bowl it was an instant loss.
