This
is a great site. Once you register, you're able to 'play the game'
every hour, which gives you a shot to win free bitcoin. Playing the game
consists of entering a captcha check, which rolls the dice, and wins
you either a small (or large) amount of bitcoin. It seems as though most
of the time when you roll, you win a small amount of bitcoin.
