Something not working, a download that didn't arrive, or a puzzle you think has a mistake in it? Say so — especially the last one.
A download didn't arrive
Check your spam folder first — that's where it usually is. If it isn't there, email us with the address you used and we'll send it again.
Found a mistake in a puzzle?
Please tell us. Every Trigon was worked out by hand and then typed up by hand, so although they are checked, an error is not impossible. Send the book number and the puzzle number and it will be looked at properly.
If a puzzle really is wrong, you'll get a corrected book and our thanks.
