Terms
Buying a Trigon book gets you the PDF to keep, print and solve, as often as you like, for as long as you like.
What you're buying
A digital book in PDF form. It is not a physical book and nothing is posted to you. Printed editions are sold separately through Amazon and other booksellers.
What you may do with it
- Print it, as many times as you want, for yourself and your household.
- Keep it forever, on as many of your own devices as you like.
- Solve the puzzles anywhere, including on a beach, which is the point.
What you may not do
- Share the file, upload it, or pass on your download link.
- Sell copies, printed or digital.
- Reproduce the puzzles in a book, magazine, app or website of your own.
These puzzles are the life's work of one man and there will never be any more of them. Please treat them accordingly.
Delivery
The download link is emailed to you as soon as payment clears, usually within a minute. If it doesn't arrive, check your spam folder, then email us and we will send it again.
Refunds
If a file won't download, won't open, or isn't what was described, tell us and you will get your money back. Because a PDF cannot be returned once downloaded, we don't generally refund simply because you changed your mind — which is exactly why there are two free books, so you can find out first whether you enjoy them.
If you find a genuine mistake in a puzzle, you will get a corrected book and our thanks. That is not a refund matter; it's a favour to us.
Prices
All prices are in US dollars. Sales tax or VAT is added at checkout where the law requires it, and is handled by Lemon Squeezy, who are the seller of record.
