Gamification is one of the ways that Bitcoin and other cryptos have encouraged adoption of the coins. Now, these online games are designed to entertain you while advertising is placed in front of you. The mixture ranges from static ads on the page to your having to click and verify that you let your screen sit there for several seconds.

Yes, I earn referral commission if you click these links -- but if you'd like to start nudging toward trading currency, then consider earning some through your time rather than money. If you are in a long, boring meeting, for instance, you could be playing and earning.

Right now, I play a lot of RollerCoin. This arcade game crypto mining pool uses advertising flashing by while I play their version of Pong and other games. I like the games, and I like gathering hashing power, which mines along for me while I sleep. I can buy little miners that stay permanently, but the power I earn playing expires, and I have to play every day (within 24 hours) to keep up my mining computer level. It's adorable and it has been working for me.

My second favorite is CryptoMining Game. This is a world where I wander around collecting symbols that stand for crypto that I can exchange when I collect enough. Like RollerCoin, I can upgrade my equipment using crystals and whatnot that I find wandering around the world. 

If you are a survey taker, then your points in Cointiply can add up fast as well. There's not much there beyond deliberately clicking on ads to earn little points, but the surveys pay a lot of points. 

Tell me what your favorite is, and yes, feel free to use your referral links.
