Odd & Even

Each extra region is connected, even if only diagonally. This one should be slightly easier than the last.

Every digit is given twice, and yet it still seems like it might not be enough. Except these are unfriendly digits, keeping away from their closest relations. Can’t we all just get along?

These digits aren’t looking to socialize. Next-door neighbors, or maybe one door further down, that’s it. No need to get to know anybody beyond that. Near neighbors only!

It might be tempting to try to solve this using only the green lines, with the pair of odd and pair of even cells to close the deal. But let the odd and even cells remind you: this is a quadro puzzle. The 2x2 rule will help!

N is for Number, like the numbers 1, 5, and 9. N is for Nine, which along with 1 and 5, are indexed columns. N is for Not planning to continue with this “N is for” routine.

A heart beat is one of the most recognizable electrical signal displays, which is how I know this isn’t a healthy one. There should be two spikes, close together, but I do what I can with a 9x9 grid.

Where is Yoshimi when she’s needed most? The giant Pink Robot is right there, and it doesn’t look very friendly. Sure, its non-Flaming Lips might look like it’s smiling, but it’s just built that way.

Some days you’re a three-cell maximum cage, and some days you’re a three-cell minimum cage. Most days you’re not quite the highest or lowest, but still pretty high or low.

I know all the digits are facing the same direction, but just imagine that the puzzle rotates so the 75 is read right-to-left and the 74 is read bottom-to-top. Not at all related to Circuit, despite superficial similarities.

Modern integrated circuits are mass-produced and extremely tiny, but I remember when even products shipped by manufacturers like Sony had internal circuits soldered together, and chips glued glued in place.
