Dice game isnt worth of time if you use only faucet and if you dont use your own money to gamble ,also poker if you play only freeroll tournaments you cant risk your won money and you can win big 0.1-0.5 btc is biggest prize which I saw that we can win in poker sites which accept bitcoin but maybe even more I really dont know also there are faucet sites where you can earn big with gambling without risking own money.Also i founded site called yabtcl where you can get free lotto tickets and won nice prizes,I love play now with 0% risk and now I am am carefully when i deposit own money to increase faucet size.
