Review for Big M Casino Review For Big M Casino Google User Jun 21 '17 at 13:14 First time on Big M. I enjoy gambling win or lose so even though I lost it was cool being out in the ocean. However a rule they have that I was not aware of is you have to cash in your chips and slot voucher while at sea in international water. So besides loosing I am stuck with chips and a $23 slot voucher. View full site to comment or like
