If you are looking for a good bitcoin site to play on for slots I have finally found one or at least just the provider who I have not seen before. The provider is Gameart and they can be found on Betcoin. Aesthetically pleasing and very good bonus structures for most of them. a bit volatile but I have had very good success. There are about 20 games and I like most of them. The site does not have much to offer for deposit bonuses but they are very quick with withdraws, within 24 hours and most of the time within 5 hours. they also have a pretty good poker room.
