Just curious if you ever got an answer and got it published? I would like to eventually add a casino location probably with nothing more than skill check devices as it’s more a poi but if I’ve got time to build a few actions via verse UI I will. I’ve seen people with spinner boards and even if you just had a Daily Gift which epic showed off themselfs in the Santa Lego Template in the POI would be fine, just not sure if even the location or mention of the word is allowed 
By the way you’re game sounds great, if you ever got it published you should leave your code here for folks to check out.
