Blackjack Fun!
When I was younger I was introduced to Rain Man, and it always impressed me how Raymond could make a lot of money playing blackjack. The movie seemed to imply that Raymond was good at Blackjack simply because he could "count cards", and it turns out that simply knowing what cards are left in the shoe is enough to do well.
So I wrote a blackjack bot that would only hit cards if the probability of a viable card was above a confidence threshold, say, .6. This will only result in a ~44% win rate (after ~6000 hands played, of course).
Take care!
