I am getting the hang of them more and more, and it's so hard not to bet everything away, LOL! My fav is freebitco.in though. Gosh... I have 20k sat there from the faucet, and all I want to do is use it all for betting, ha!
I am not addicted; the 20k is still there, but wow... I have an itch to scratch for sure.
Dice games are among the funniest I agree. But freebitco.in is not quite a place for dice actually. You better use their faucet to collect sats and transfer them to a good dice site, like PrimeDice for example. You can just change your bitcoin address there on the deposit address on a dice site. Good luck!
