I'm guessing a bitwise nand? I haven't actually given the puzzle a go, but seeing what numbers appear in the &-cages, it seems quite likely.

I probably should have paid more attention to the use of & as the symbol for the operator.

Complete Change of Original Post: Bitwise And : One will have to use Binary, just as one does for Bitwise Or

To have a bit turned on (= 1) represented in the final answer, every number in the cage must have that bit turned on (= 1)

(6,7) & = 6
110
111
110

(2,5) & = 0
010
101
000

(3, 5, 7) & = 1
011
101
111
001

Ah, I had forgotten you submitted one like that, I'll take a look and let you know.

The next user puzzle will be another one by kus_theo, on Saturday.

Just wanted to jump in to say that I loved the 0-11 user submitted puzzle, and the -1 through 4 bonus. More "off-script" puzzles please!!!

Getting to it... I'll try to recreate the puzzle (I sent it in so long ago that I've lost the paper )

EDIT: I responded to your email about it... just a mixup of coordinates

My twin solver is currently choking on this puzzle pair, I'll need to fiddle with the code a bit.

What I know so far: puzzle 1 has 48 solutions, puzzle 2 (the one with the bitwise operators)
has more than 3000 solutions (don't know the exact number yet).

Of these solution sets, exactly one pair needs to be identical.
