I'm not sure if this has been asked before, do you guy know any good websites that aren't based on pure luck?
Besides Poker and similar card games, I've recently found a website (thanks LoyceV) where you create bots to compete against others and make money in the process.
Website is
DrownHim. I'm not promoting this website because I'm affiliated with it, but because I would enjoy some competition!
Come join and see if you can beat the winrate of my own bot.

But like I said, I'm not affiliated with that website, so I would really enjoy any other websites you've come across, I like games where it's not all luck, and you get to test your own skill and logic to maximise your winnings. Of course full skill-based games like chess, checkers, or whatever aren't really a suggestion because there's 0% luck element involved, in addition to the fact that they're almost "complete" games, where a good enough bot will practically never lose.
So yeah! Let me know of any other games like Poker/Drownhim.
Skill based games is just increasing the probability of winning and its not a sure win even it based on skills. Remember that those who have similar skills are the ones who is chosesn to battle into so the odds are also 85% skills 15% luck. Yes! Even skillful players are lost to rookies.
