I have a suggestion to make on the gambling system. When i was gambling i got up to 50m from 2m then lost it all. But that's not the point. After losing that money i got another 2m got up to 15m then i accidentally clicked the "five" button instead of blackjack. that 10m away and i ended but losing my money again.
I suggest that you have some kind of warning message when people click on the five button because that made me angry. If you could do that it might save some people a bit of money.
