Freebitco.in is the revolutionary faucet in the Bitcoin world. Their all games are provable fair and every week ten lucky users get huge bitcoins where first prize can be up to 4BTC. On other hand freebitco.in has an awesome option to multiply your earnings. Though there are a big chance to lose all of your earnings, but still you can made a decent amount of bitcoin using this multiplying option. Below I describe the whole process with screenshots for your best understanding.its really funny 
I do agree that their all games are fair, but I don't recommend to use their site to play dice or hi-low game because they got highest house edge 5%. Even with 1% house edge also winning money from this game is quite difficult but with 5% you never can win so don't waste your money in this game. Always check for the house edge in dice game before depositing your money.
