What exactly is the problem? You are saying that you play roulette but when you win, money does not get credited to you? Even after some time?
Before your roulette upgrade(which i don't like the min bet now is like many others, high as hell 1 mbtc), and here's the situation it was:
Betted like 1 mbtc all over the board, spin the ball, lands, whetever I win or lose I have my 1 mbtc back.
I tried that 3 times to be sure, same result.
Then I said, ok, maybe it's the coin problem, let's try with doge, betted 750 per 3 times, and whetever it was a win or lose, I had my money back.
If I wanted to play on a roulette without money I would just stare at the roulette, it would had been the same.
You are right. Some other players also reported Roulette not counting wins and losses. But Roulette has been removed already and we have new games now which are working well.
