You can use your love for games and turn it into a profitable pastime! Such apps as Bitcoin Aliens, Coinbrawl or ChopCoin can both occupy your hands and get you some of those coins. However, bear in mind that the profitability of this option is not any higher than that of the previous section.
If your definition of playing games involves betting, things might get a little bit more exciting here. If you already have some bitcoins to spare, you can try using them on betting websites (such as satoshidice.com) for a chance of multiplying what you have. Nevertheless, it is very risky, as you might end up with less than you came in with. On the other hand, there is a chance that you can win big, so the choice is up to you.
