As we step through the solution, I would like to have newly filled in cells displayed in an intermediate color (green?). This would make it easier to see which cells were just updated. At the next step, they could then change back to blue as the solution progresses.

BTW, the Killer Solver is also known as Sum-Doku (by Dell Magazines)
Right now though I'm stuck in France and it's super hot, can barely think. But a good job for when it cools down

Hmm. Jan to March seem missing. Hope there's not been a database error

It should be a strategy, but there are also other configurations so it could be messy.
Nevertheless, so surprised it's taken 15 years to discover!

I am trying to practice the tough strategies. Is there a way to select puzzles that only need strategies up to a certain level such as Tough strategies. I thought I could use the column heading in the daily sudoku calendar but the first one I tried in the tough column was April 8 2020 and required a diabolical strategy.
If you mean why do some puzzles have diabolical strategies that is because the strategies used is only partly what counts towards the score. Some puzzles will be easy apart from a bottle neck which doesn't push the score over the grade. I do try an filter away puzzles that are like this too much. If you want to read more about the grading there is a paper here.

The rules I envisaged was both players could fill in any cell at any time and get a point for each correct number. Negative number for incorrect - to discourage spamming. There is an issue of deadlocking, mainly that who gets it first is down to the timing to the server.
Then there is the whole issue of managing queues of people and matching them up. Asynchronous programming is a bit of a dark art. Probably require a good but expensive developer to get it right.
Would be nice at this time, I agree.
I will keep in you in mind for testing then.
