A puzzle in the post, once or twice a month

One or two emails a month. Each one has a printable puzzle in it — an actual puzzle, not a link to a sales page — plus one set a month that isn’t anywhere on this site. About one time in four I’ll mention a book. That’s the whole arrangement.

Who are these puzzles for?

Optional — it genuinely changes what I make next.

What happens next

I’ll email you once, straight away, asking you to confirm it’s really you. Click the link in it and the first exclusive set arrives. That confirmation is my record of your consent, which Canadian anti-spam law requires me to keep, and it’s also what keeps robots off the list.

Every email after that has an unsubscribe link at the bottom and it works the first time you click it. I don’t sell or share your address, ever.

I use a company called Kit (kit.com) to send the emails, which means they store your address. How I handle your information

The free shelves stay open either way

Signing up saves you a trip back here; it doesn’t unlock anything. Every set on this site is free and open whether you join or not. See every free set
