Not only is this the kind of in-your-face crap everyone wants removed from Warlight, but it's also trying to coerce minors into gambling, which is illegal!
The gambling support is 50-50. I personally like it while you hate it.
Minors gambling is illegal, but Warlight does not promote it, and in fact, fizzer condones it. You are responsible for reporting your age during the beginning survey when you received coins (Are you 18 & over?). If you report false, that would be fraud which is illegal. This is not a children's game, it is a game for all ages. There is as many opportunities for adults as there are for children.
And btw, I would like to see YOU work full time on a flash game and not implement any monetization methods ever.
