The last hand-made puzzles in the world
Every Trigon was worked out on paper, by hand, by one man. He is gone, and there will be no more. This is how it happened.
A British board game
Trigon began as a board game, invented by Alan Frazer Dackers — Dax to everyone who knew him, and The Boffin to everyone else — together with Lester Jordan, who went by Sgt Bilko. Between them they worked out a puzzle built on triangular dominoes, where each triangle carries a number on every side and a centre number that adds them up.
The idea is simple to explain and very hard to exhaust. Give a solver only the centre numbers and there is exactly one route to the answer — no guessing, no luck, no trial and error. Dax's rule was absolute:
“Never put in a number because it will fit. Only put in a number because nothing else will fit.” Dax
Scribbled on paper
This is the part that cannot be repeated. Dax made every single puzzle by hand, working them out on sheets of paper with a pencil. Not one was ever generated by a computer. He also decided the difficulty of each one himself, and when he marked something Extreme he meant it.
Peter Rutter was brought in to turn that output into books. He digitised the scribbled sheets into properly typeset pages, assembled them into books with covers and solving instructions, and put them out for people to download, print, and solve with a pencil and a rubber — plenty of rubber, because everybody makes mistakes.
That happened once a month, every month, for thirty months. Each book assembled by hand, one page at a time.
Then it stopped
Dax and Lester have both died. No new Trigon will ever be created, because the only person who could make one is no longer here to make it.
What survives is 3,252 puzzles. That is the complete and final collection, and it will never grow by a single page.

Why they're back
The assets survived — the spreadsheets, the original sheets, the number sets. Peter owns them, and has spent the last stretch of time putting every puzzle into one catalogue, checking it, and rebuilding the books to a modern design.
Sixty books, arranged so no two puzzles in the same book share a solution route. Same puzzles, same logic, same rule about never guessing. Nothing added by a machine.
There is also, now, a version you can play in a browser — which Dax would probably have found funny, and then immediately tried to beat.
