There are a lot of games that you could download on google play store that you could play games while earning cryptocurrency. But the only game that i have played is flappy coin that you could earn a small amount of satoshi and it has similarity with the game of flappy bird. I already have uninstalled the game because it takes a lot of time for you to reach the minimum withdrawal and it is really hard to earn that you also need to refer a lot of people for you to earn a huge amount of Satoshi, that is why i suggest not to try this kind of games because it is a waste of time, i think it is much better to play in a online gambling site because you can earn a huge amount of profit.
