How is it possible to solve a Kakuro with 44 squares in 36 seconds, i e 0,8 seconds per square?

There are people who solve Rubik's cube under 7 seconds.Each solution involves more than 20 moves.  Comparing  those times and  FexSHO's times gives perspective.

Nice analogy. Rubiks cube is my other passion: World record is at 5.25 seconds. About 50 moves are necessary. So they do it about 10 moves per sec and thats crazy.

I need under 18 secs for 70 moves: my speed is poorly half of world record.

At kakuro practice is everything. I am enjoying the puzzle books of conceptis puzzles. Thats a good practice. Also you can increase solving times with practicing at nikoli.com and www.kakuro-world.com.

How is it possible to move the pointer to a square and click it and hen move to the right figure on the keyboard and click it in under one second?

I imagine the best solvers here use the arrow keys to move from square to square, which would make it a lot faster. I don't get to do the puzzles, but I know I am a lot quicker if I can just keep my hands on the keyboard and not worry about the mouse.

Oh, I'm not the only Rubik's Cuber here, that's cool :) I average about 11 seconds for it. But yeah, I use arrow keys to move around quickly, although I should probably use the mouse more for long movements...

Hi.

A question for ones who solve even the hardest puzzles in less than 10 min: do you go through the procedure of substituting "candidates" mentally and at a very high speed

or do you "feel which is the right digit" without going through any process of verification?(like some mental calculators who can't explain "how they do it").

Also: do you come up with all possible sets of digits for a given line/column (or perhaps remember them?).

Thank you.

Wow, lots of cubers here! Somehow I missed that back in 2016. I'm averaging around 19 seconds right now, can't seem to get lower, luckily I'm making some nice gains on the larger cubes.

I'd also be interested to know if people have a sense for what the right digit is in a series of candidates. I know while doing slitherlinks and some other puzzles that I have a good feel for what paths will lead to a solution, but not for kakuros.

Well..it's not that hard to come up with all possible sets of digits for the columns with fewer solutions, honestly. 

And I personally don't do the "feels like the right digit", I've never had that feeling! I count everything. 

And why can't we use the mouse while counting? We have two hands, one on the numpad and the other on the mouse. You don't have to do it separately -- you can move the pointer while inputting the number (takes practice). And yes you can do it in under one second, so long you're not going from the far left to the far right of a 24x14 puzzle.

My speech, Am I.

Its the same when I solve those kakuros. Perhaps I have just more pracitce than anybody else ;)

Hello again.

I would like to ask  morl,arbor8,FexSHO,matjaz,qqref (others are welcome to answer too):  do you use the option that displays possible combinations or you keep them all in mind? or perhaps there is some third way?

Thank's.


morlPosted: Sat Feb 15 2020 05:14 am

Sometimes I'm faster if I use it, but never for sums like 3, 4, 16, 17 etc, as these have only one possible composition, and are thus easy to keep in mind. I use it mostly for some 4-7 digit sums where 2 digits are missing.

Thank's.

More interesting is how fast you can get with a try and error technique. I never use it, but maybe you can get really fast with it. Does anybody try it?

Hey morl, todays puzzle under 4 minutes is insane in my opinion. How did you get that? Did you use big sums over the four areas in the corners?

Greetings from Germany, fexsho


morlPosted: Mon Feb 17 2020 09:48 am

I don't use trial and error if I don't need to, as it is rather slow for me. And for yesterday's puzzle: It helped me a lot to not focus on one area of the puzzle, but solve the easy intersections first. Example: one line has 4 cells which sum to 11, and the other line 4 cells which sum to 28. More often than not such starting points are at big rectangles.

And I practice a lot at ATK Kakuro. I like the puzzles there.

By the way, I'm usually not as fast at easy puzzles, as you can see at the puzzle of January 20. You solved the 34-cell puzzle in just 22 seconds. How did you do that?
