This article employs a common tautological use of ‘algorithm’ I see more often than I’d like. It explains that there is an underlying method to something, explains how the method works, then further clarifies by explaining that it’s an algorithm, with a link to the Wikipedia entry for the word. It’s framed almost as a reveal, as though the rest of the article hadn’t already explained the same thing in other words. There’s some magic to this word that gives it some kind of recursive emphasis - you can provide a completely sufficient explanation for an algorithm without naming it one, and somehow up the stakes by invoking the word all the same.

Another comment, more on-topic: it may surprise some to learn that the ‘crane’ or ‘claw’ games in arcades and rest stops are also games of chance, not games of skill. They are programmed with the value of their prizes, the cost to play, and the operating margin the operator would like to have. The machine handles the decision of who wins, when.
