While you wait to get free'd theres a game called minefeild where you gamble little amounts of bit coins by clicking on squares, the more squares you click on without setting off a mine, the more you win. The trick is really to cash out as soon as your up.
Here is a referal link, yes if you loose i will make 5%,
