Yeah, there are also some games that pays at first then after some time of spending and earning good amount while we play once we request a payout they will not pay us anymore.
Sadly, most Bitcoin games do not pay because they're a fraud. There are only a few legitimate Bitcoin games which pay their players, but their reward is ridiculously low. Earning satoshis for a few hours of playtime is not worth it. However, for newcomers into cryptocurrencies, Bitcoin games serves as the perfect educational tool. Compared with faucets, Bitcoin games are similar since they pay you pennies in return of your hard work and effort.
Despite this, if you're looking for fun Bitcoin games to play no matter their reward, then I'd recommend Coin Flapper, Bitcoin Billionaire, The Bitles, Crypto-Games.net (Gambling), and even Battlebit. In the moment, those are the most fun Bitcoin games in existence, but there could be more of them available which I'm not aware of. As far as I know, the emergence of new Bitcoin games has been very low. It seems that the interest of developing Bitcoin games, is not much these days compared with the early days of Bitcoin. All the attention seems to be on ERC-721 tokens within the Ethereum blockchain, since it allows games to operate in a decentralized fashion adding much more flexibility than Bitcoin.
Nevertheless, I believe that more Bitcoin games would emerge in the future, right after RootStock becomes practical in the mainstream world. Just my thoughts
