I did it twice and it worked both times, but I guess as they say, when you're right 52% of the time, you're wrong 48% of the time!
Also, the explanation makes perfect sense, which satisfies me for some reason. Kind of the exact opposite of the Monty Hall problem.

It’s interesting to me to think of this as a magic trick. Implicitly I assume that “magic” means if you pull off the sleight of hand correctly, it’ll work. Probabilistic magic is a new idea to me.

Didn't work until I realized the face cards were only supposed to count as 5, not 10. But yup, it works. Neat!

Reminds me of this puzzle I saw earlier this week.
One of those moments where it feels I can see the internal machinery of the internet. Article A led to someone reading and posting article B. etc.

I haven't heard of it phrased this way, but most people who study CS know a bit about Pollard's rho algorithm for factorization, which is just a practical application of basically the same idea.

Huh, neat. The first time worked. Second time, near the end, my brain said, "ooh, looks like it'll be one off." Landed on an Ace.
