The JSudoku column includes the solver order that I use and the number is the "Complex intersection" that JS uses, plus any chains. Not allowed to attached the solver order to this post but email me if you want it. Download it to your JSudoku software folder to get JS to use them. Uses far fewer chains. Can then compare it to a table I made for 10 assassins.
Observations.1. HS starts with a technique and designs a puzzle around it. My As, puzzle first, then try and solve it.
2. HS wants the two machines to fail (but not always, see HS 16). My As, at least one of machines succeeds on initial puzzle, and gives more options for variety of WTs.
3. HS is okay with one-trick pony. My As, try to also make hard middle and ideally, a hard end. So, big difference in Andrew's step average, between HS and A. This may be why Andrew's ratings for Assassins are slightly higher overall.
4. HS must be interesting. As must be interesting. Neither is hard just for the sake of it.
5. HS and As on a spectrum. So HATMANS thought about a thin line is probably correct. But keep the HS coming if you can HATMAN! But surely, we have to run out of finding new techniques!!
