When Emil was presented with “NE_ _ _ _ _ _ _ _ _ _” roughly 17 percent of all the letters in the phrase were visible. Only about 30 people had been in a similar position to Emil’s—that is, with less than 20 percent of all letters revealed—and none of them had ever managed to win.

Again, my analysis is based on the available data, which has some holes in it, and doesn’t date all the way back to the show’s debut in 1975. But based on my sample, it’s safe to say that de Leon’s probably is the most amazing solve ever, from a statistical perspective. When you consider that “New Baby Buggy” is a phrase few people have ever heard, let alone would offer up as a guess were they in Emil’s shoes, the guess is even more remarkable.

Curious to see if you have the solving skills to crack a puzzle like Emil’s? The quiz below includes puzzles from the 15 bonus rounds, out of over 2,000 in my sample, in which the fewest number of letters were revealed but the contestant still managed to guess the correct answer. Armed with the same letters, see if you can solve these puzzles in that short, 10-second window.
