How To Do Hard Sudokus In 10 Minutes 

They have two games on steam too, there is no escape :D

I only read your comment after solving this one... the is no hope now.

Bit too late for me as well, I think...... :D

All the games I love the most that also has longevity, are the games that also makes me see them when I close my eyes. Sudoku, minesweeper, antijoy, euclidea, solitair/freecell, and so on (pretty much any pattern-based game, even some first-person shooters that have such traits). So you are not alone. I usually stop playing the games when those symptoms appear, as my inability to fall asleep within half an hour unless exhausted, turns into an hour because of it. Sometimes I switch to another game. At least antijoy no longer has this issue for me, as I solved its campaign and it only rarely gets updates adding a few new levels. ps: I used to have no issues playing sudoku a lot. Probably as I didnt solve it based on patterns back when, but rather by methodically step through it. It all changed when the fire natio- When I downloaded brainums sudoku app, as it had an in-built trainer for solving by pattern, and super useful highlighting that lets you see your notes easier :/

@@feha92 I heard this is called the tetris effect, when playing a game so often wires your mind to start thinking in that sort of pattern in your everyday life. I can't tell you how many times i'll look at a keyboard and try to see where an R can fit using sudoku rules, lol.

Mark Mays same

Exactly! 😁

Undoubtedly

Do you use an app or pen/pencil and paper?

I use their web app. I did use pencil and paper before they created the web app.

@@brianrichter8255 Thanks. Do you find using the app easier for solving sudoku?

@HowardC Yes, erasing lots of pencil marks can get messy, especially if I make a mistake. Being able to undo in the app is much easier. Corner and center marks and highlighting also make the app easy.

@@brianrichter8255 Thanks! If I use any app the puzzle is easier. I feel like I'm cheating when using an app so I use paper and pencil most of the time. I just purchased the app that these guys offer. I wonder if these competitions are app/programs or pencil and paper???

Took me about the same time. It's quite fun.

45 in r5, 45in c3, 37 in r5, 37 in c4, 89 in b4, 24 in c1. The puzzle almost done, before a first big digit. :)

17:14, pretty proud of myself. I've learned a lot from these videas

Do you use any pencil?

Me too, got it on 30:31

good job to both of you. it took me a lot longer than that.

40:24 for me, you're doing good mate! ;)

@@manuakasam Lol i got that exact time too! 40:24.

40:48!

How to begging for likes

Nobody is begging you filthy dog

I completed Sudoku in 14 minutes professional level

Probably more like a 3rd or a quarter of the time.

My firts time trying one of his puzzles and it took me an hour lmao (without watching first)

Can you say more? I too have mastered medium levels but struggle with difficult levels.

Oh dear, I'm new to Sudoku and right now it's all double Dutch. I hope to get better one day 🙏🙏🙏🇦🇺❤

It’s similar to an x-wing, but instead of row and column creating the constraints, it’s row/column and square.

Usually if a puzzle requires brute force it means it's not a good puzzle, automatically generated ones might have that peoblem

Wish someone could explain it to me. 😢❤

how did you do that

@@aldriannatawijaya6737 has to be simple practice and very, very fast pattern recognition and every now and then a puzzle just collapses and each cell found points to the next. Remember I start my times from possibles revealed - so to reveal all possibilities for all cells generally would take someone 4-5 minutes - but there is practically no skill involved - so I just remove that and start from a pattern with say 27 known cells and 54 cells with 2-7 choices in each. I typically look at cells and start solving around the digits that have the highest occurrence then progress down to the digits with 3, 2, 1, or 0 cells presenting. Then I do a quick parse across all digits looking for patterns. Sometimes the hard deciphering algorithms aquire the pattern quicker - it just out - like in seconds, sometimes I miss a simple pattern and it might take 2-3 minutes to spot the obvious elimination - but that is almost I missed a simple clue on the first 3-4 passes (human error). About 1 time in 70 I might botch the pattern if the glass screen on my smart phone doesn't play nice - but generally if you are around 2 mins 20 seconds you know sooner or later you will do a real fast time - and when you start to go well under 90 seconds its a real buzz! If I could ever go sub 60 seconds I think I would retire - game conquered - but that might take a long time and require a freaky perfect game to come along!
