This is my favorite Nutaku game atm, how exactly do i do the mini games for union quest? I've now done the secret art combo a few times but what is this 10k gamble mentioned in the original post? Are there other games? Are "food runs" all the challenges that include food?

I'm still figuring stuff out but i just hit lvl 45 the other day and it's been one of the few games i look forward to on the platform.
