Here’s a little thread on a $10,000 contest I’m involved in (which you can still enter at ). And how it grew into something beyond my wildest ayahuasca-fueled dreams. (Disclaimer:I’ve never tried ayahuasca, so maybe I'd have imagined it if I’d done a bunch)

Here’s some math: Two brilliant mathematicians + one slightly-above-average puzzle-solver = an exciting event tonight! I’m having a virtual conversation with @stevenstrogatz and Peter Winkler for the Museum of Math tonight at 6:30 pm ET.

When you're reading The Puzzler by @ajjacobs (because you make puzzles-- but also because it's a great book) and learn that the author's wife is the President of Watson Adventures while you're wearing your Watson Adventures shirt!

Originally, I figured the $10,000 I took from my advance would be a loss leader. But it'll probably just be a loss. But that’s ok. It will, I hope, spread the love of puzzling. And I feel okay boasting about it, because I didn’t create the puzzles. Go forth and solve!

There are currently more than 1,300 contestants (including at least one billionaire!). But it’s not too late to join – you can catch up on the previously released puzzles at your leisure. Even if you don’t win the money, I recommend it. The aha moments are worth more than $10K.

Thanks to the devious geniuses who wrote the puzzles: @gregpliska , @mattgruskin , Guy Jacobson, Tanis O’Connor and Max Woghiren/ @mbingo . As well as the many puzzle testers. And to Joseph Hinson and Joshua Kennedy for building the website.

ALSO: No purchase necessary, must be at least 18 and a US resident to win. You don’t have to buy the book. The intro is free on the website. Otherwise it might be considered an illegal lottery, and I would be spending time at Rikers Island.

Here’s another, a baffling twist on Wordle. (It's interactive, so you have to solve it on the site)

The theme is great historical puzzlers, so the first puzzle is this one, an homage to Arthur Wynne, inventor of the crossword.
