Well, bounty campaigns provide greater rewards than Bitcoin games, but requires a lot of work and effort to be able to produce quality posts. On the other hand, Bitcoin games doesn't require much effort for you to start earning some satoshis right away. Of course, the rewards are minuscule, but the games itself are extremely fun and addicting.

I urge you to try many of the Bitcoin games available right now for PC, and mobile devices. Usually, most Bitcoin games are available for mobile devices like Android and iOS, but there are a few which are better playable on a computer. If you're into gambling games, then I suggest that you try most of the games that have been mentioned on this thread. My personal favorite is Crypto-games.net because it accepts most of the popular cryptocurrencies we know and love today, and it includes a variety of games such as Dice, Blackjack, Slots, and more.

However, if you're not into gambling, and you're just looking for a way to earn Bitcoin without losing any money, then I suggest that you try some action/adventure games that have been mentioned on this thread. One good example is The Bitles game where you would need to complete a maze to earn some satoshis. There are also RPG-style games like CoinBrawl which allows you to earn Bitcoin simply by battling other players around the world. The higher you train, the greater your attack and defense would be, allowing you to earn satoshis easily when competing against other players.

Another great game is called BattleCoin which is like a Bomberman game, but allows you to compete with other players and earn Bitcoin in return. The list of games available is extensive, but as transaction fees become cheaper on the Bitcoin network, and speeds become instant, I believe that more games will emerge allowing Bitcoin to become used more frequently by everyday people in the mainstream world.
