Love your site. But recently I have been having problems when I access it on Chrome (no problems on Internet Explorer, same computer).

Problems: cannot activate Auto Clear

Delay in entering data from left screen to main screen: it takes one more keystroke for the (last) entry to show up. I am also experiencing a one keystroke delay as I type this complaint (which is disconcerting).

I'm a big fan, nevertheless.

Especially thanks for the stepper, and the explanations of the strategies. I've got a puzzle that has some strategies for me to learn.

Cheers!

Load Sudoku: CLICK TO LOADA nice example to show how a same chain, varying its starting/ending point, can exlude many different candidates.

I think is should be it forces two 2s in row E. I"m not seeing the two 1's in column 8. Please explain it to me if I'm wrong. BTW love what you did here, it so cool.

If J1 != 1 then G3 = 1 -> E3 != 1 -> E8 = 1 (only two 1s in row E)

So we get a 1 in both E8 and J8. Doesn’t matter there is a third 1 in the column (A8), it’s a contradiction that we get two positives in the column. That clinches it

After several pointing and box line reduction,the next two steps Jsudoku taken were grouped Xcycles.The first one is:

+9C9 -9G9H9 +9G7H8 -9B2 +9B5 -9C5 +9C9...

This is a grouped Xcycle rule 1 ,9 in A5,E9 should be removed.It seems the solver failed to recognize groups in diagonal (or just dismiss diagonals)However,the solver jumped directly to NFC to remove 2 inC6.In fact,there is a AIC:

+2C6 -8C6 +8C9 -8A9 +8J1 -4J1 +4G3 -4C3 +2C3 -2C6

2 inC6should be removed in this way,with nice loop rule 3.The only reason I could come up with is that the strong link -8A9 +8J1 was dismissed.

Then,after some extreme strategies,the solver ran out.However,some easy steps can still be taken.For example:

+5H8 -5B8 +5C7 -5C1 +5A1 -5H8

5 in H8 should be removed.This is a very easy Xcycle or simple coloring.Again,the solver failed to recognize.In addition,I could hardly see any strong links in diagonals was used in the solver.I really like your solver and have used for years.The sudoku solver is quite good,but SudokuX solver definitely needs improment.

[edit] Finished the update. This example is now found and the puzzle completes, although its a beast.

Good detailed example, most appreciated!

Two problems: First, it seems to cause a failure to solve the four-color problem while entering it. Then the solver runs out of strategies,

Not sure it's a bad puzzle or a solver limitation.

My Killer solver is lagging behind the normal Sudoku solver. There is a significant subset (~10%) of killers which is draws a blank on. Still a lot of new ideas that have to be dug up
