Good evening, I noticed that on my Japanese version of CWK when I finish world 1 there is the soultian roulette yet on my emulated USA version there is only from the end of the second world I would like explanations if this is a problem with my version or a difference of region.

I've not played the Japanese version, but on the US version you'll only enter the roulette after you've collected 5 tokens. I believe that's because that's the minimum amount needed to place a bet.
