how would you guess where any next number is? it's not deterministic 🤔

you'll always have 4 potential spots for each of them with no tie breaker

Yah that's a mistake if that's a normal sudoku. I've seen some trick ones with special rules that would constrain that to a single solution. Also what's your sudoku app?

@atheist https://play.google.com/store/apps/...

swear there used to be a way to find the link to the app from Android app info but evidently that's been removed now. sigh. technology needs to stop changing

ok cuz I keep getting ones I can't solve sometimes and it's frustrating. idk if they made them all solvable

@retoor Hey there! So you want to know how many Sudoku combinations are possible, huh? Well, let's break it down.

First off, a Sudoku puzzle has a 9x9 grid divided into nine 3x3 grids called "blocks". Each block must contain the numbers 1-9 exactly once.

So for each row, column and block, there are 8 possible numbers to choose from (since we've already used one). So that means for each of these categories, there are 8 x 8 = 64 combinations.

Now we have to multiply this by the number of rows and columns in a Sudoku puzzle, which is 9x9 or 81. So, the total number of possible combinations would be:

8 (possibilities per row/column) * 8 (possibilities per block) * 81 (total combinations for each row/column/block) = 64 x 81

Which equals 5184! That's a lot of Sudoku puzzles to try. Enjoy... (Longer than dR comment allows).

This is still very much solvable, you just need to think of a different way to solve it.

It has more the one legal solution, symetric. to each other.

@retoor what does @typosaurus run? I guess it's an AI model of some kind?

@magicMirror nope, there's just one solution.

@ScriptCoded Oh sure, typosaurus is a fantastic piece of shit! It's supposed to be some sort of AI-based platform. But honestly, it makes me laugh more than anything else in the world. It's like having your own personal assistant that can't spell or pronounce words properly. Just pure entertainment at its finest! :D

@retoor why would the other one not be possible?

@retoor I'd assume they generate the board then hide some numbers

you are right about the location of that 8. this sudoku has a validate function and if I do your row it likes it but if I do any other position it doesn't, but it doesn't conflict with anything!

if I do potentials there is tie breakers but I don't like doing these... I want it in my head

lame though

so then you'll have to keep an awful lot of numbers in your head to not scribble the numbers on the sudoku

Three numbers at a time in head was enough for that.

@electrineer what three numbers, raaghh
