Ah yeah, as much as it's fun to play bitcoin games, I wouldn't recommend playing them to 'earn' money.
many methods of getting bitcoin for free like using the game. I do not think this problem has two objectives to have fun and earn money from playing games?
yes, having fun while earning, but for sure you gonna make just minimal amount of satoshi, example in faucet its hard to look for faucet that gives 1000k. Free bitcoins are always less in volume

How free bitcoin is, it is similar to free samples that you find in the supermarkets, you go take a bite or a taste and if you like it you have the option between going into every supermarket and taking free samples or you could just buy the whole thing the first time, the point is that if you want to really get bitcoin you have to work for it and not just relay on free samples that are not really worth it.
