Sudoku Pad

Standard Sudoku Rules apply to the final numeric layout: Every row, column, and region (to be determined) contains the numbers 1-9 once each.

Tired of all those puzzles where "there are no 2x2 areas"? Then this is the grid for you!

Each of the nine regions has exactly one 2x2 area in it. None of the 2x2 areas touch each other on any edge or corner. The sum of the four digits in each 2x2 area is a multiple of 2. And at no point on the grid is there a "four corners" where four regions all meet.

Cells separated by a small white dot have a difference of 2, and those two cells are in two different regions. All white dots that meet both conditions are given.

Digits in a caged cell indicate how many sides of that cell are borders of its region. All possible caged cells are given.

Digits on a grey circle indicate how many cells of its own region it can "see" in all orthogonal directions, not counting its own cell. Region borders block any further view. All possible grey circles are given.

Arrows outside the grid indicate the sum of all the digits along each given diagonal that are not in a 2x2 area. Digits may repeat along the diagonals when allowed by all other rules.

Well, friends, this will be my last Sudoku setting for a while. I have a life-long dream of making feature-length motion pictures, and the hours I spend working on new Sudoku puzzles is time NOT spent on moving my dreams forward. I won't say I will never, ever make another puzzle, but it will be a long while.

I discovered Logic Masters and the incredibly creative world of Sudoku variations in 2020 thanks to a random video recommendation on YouTube which was "Cracking the Cryptic". I had no idea that people had been getting so inventive: Arrows, Little Killers, Between Lines ... it was very enlightening, and I tried my hand at it. I have some puzzles that are very weak, but happy to say the five puzzles before this one have all scored well and are worlds better than the first ones I made.

And if nothing else, I can say I'm the one responsible for the "Battlefield" variation that actually became a part of some Sudoku-pedia pages!

I had hoped to have a second appearance on CTC at some point. I have some puzzles I'm quite proud of, but I shall have to be content with the one puzzle of mine that did get solved by Simon. I will never be a Phistomophel or other notable name (though he did have positive comments on two of my puzzles!), and I shall be content to know that "BattleField #1" lives on in the CTC YouTube archives.

Thank you all for a lot of fun, both as solvers of my puzzles and creators of puzzles I managed to conquer. I have learned a lot of new strategies, including coloring cells and using the Law of Leftovers, and more I can't remember right now. It's truly been a fun education.

And if you want to keep an eye on what I'm up to in the cinematic quest, you can copy and paste to follow along here:

Beautiful puzzle :)
The AND in the difference rule broke me a little bit but it works out wonderfully

All the best with your future endeavours!

Really good goodbye-puzzle. All the best, Big Tiger.

I met logic masters the same way you did around the same time. I have no idea how to set puzzles but I solved a good amount of construction & deconstruction puzzles and this one is a great utilization of deconstruction logic. 10/10.

I missed a necessary piece of instruction when I created the first Sudoku App link. Note that the small white dots denoting a difference of 2 between the two cells ALSO denotes the border between two different regions! The instructions are now correct here on LMG, but not yet updated on Sudoku App.
