today's (June 12th, 2022) 4x4 difficult is tricky
Someone asked about this puzzle on youtube, my reply copied here:
That is quite a tricky one.
Here is the puzzle for reference:
https://i.imgur.com/nDzx7Kw.pngI think a first step is to realize that both "2-" cages have to have the same numbers (!)
So either both 1,3, or both 2,4.
If they are both 1,3, then the sum of all cages except for the "1-" cage is 13 + 10 + 4 + 4 = 31,
which leaves 9 for the "1-" cage, which isn't possible.
If they are both 2,4, then this leaves 5 for the "1-" cage, which is possible, and can only be 2,3.
I'll probably do a short video on this puzzle as well, thanks for pointing it out
If people know a quicker path to the solution, please post it here
