Re uniqueness, this seems to be a bit like numberlink for me, so perhaps bear with me on some future puzzles. I'm pretty confident these are all good though!
The first puzzle is a somewhat narcissitic-yet-trivial example - although hopefully it clarifies exactly what you are supposed to do with loops.
#268 Curve Data – rated (stupidly) easyMaybe this next one isn't quite a medium, but seeing as it's the first one for the blog I'm going to relax my strict regime just this once!
EDIT: A previous version had rather more solutions than I thought. This one I think is unique!
2nd EDIT: It isn't! Back to the drawing board... :)
3rd EDIT: I got someone to test solve this first :p

For the second one, I found that the location of the middle line of the A is not unique...does that matter?
ReplyDeleteAh - I see the extra set of solutions I'd apparently managed to rule out. This one does have some uniqueness issues, I *think* a quick fix is to move D to R2C2 and E to R8C8. I'm too tired to check that properly now though...
DeleteThe updated version seems to have a couple of solutions, too. (The bottom of the C can extend more or less, with the right leg of the A / entire B growing/shrinking vertically.
ReplyDeleteFor whatever reason, I had convinced myself that the B couldn't possibly span 4 rows - I see what you mean. It's a much more flexible shape than I'd given it credit for!
DeleteBack to the drawing board...
