Hi Groston
No, a
valid puzzle can only have one solution. If it has multiple solutions, find a new puzzle site!
I looked up the site and this puzzle type has the extra constraint
Quote:
"All possible 'v's and 'x's are shown in the puzzle, so if there is no 'v' or 'x' between two touching squares then they do not add up to 5 or 10.
This means that every time a 1 & 4 touch or a 2 & 3 touch there is a 'v' between them. And every time a 1 & 9, or 2 & 8, or 3 & 7, or 4 & 6 touch there is a 'x' between them"
Unfortunately, your solution has many 1 and 4 touching that are not 'v'ed so your solution is not valid. Good news for trusting that site!
Good on you for trying all these. Mind bending.
Cheers
Ed
