4x4 puzzles

Someone must have tried it. Any specific challenges? Are they harder / easier, possible even?

By that I mean 4x4 boxes, i.e. 16x16 cells!

Hi

I've done 16x16 puzzles in the past and 25x25. I'd say they were harder and more time consuming, but definitely doable. Biggest I've ever seen is a 48x48!

Harder/easier then what?

An 'easy' 4x4 (boxes) sure isn't harder then a 'hard' 3x3 (boxes) puzzle in my opinion...

The main difference between a 4x4 and a 3x3 is that you need to pay more attention, as in more numbers to consider etc... :)

Lindy,

don't you mean 49x49?

I've done 16 x 16 cell puzzles and would agree with Animator "An 'easy' 4x4 (boxes) sure isn't harder then a 'hard' 3x3 (boxes) puzzle" and "The main difference between a 4x4 and a 3x3 is that you need to pay more attention, as in more numbers to consider etc... "

It does make a refreshing change, from time to time.

4X4 Puzzles

A 4X4 puzzle uses Hexadecimal I suppose.
A 5X5 puzzle could use the letters of the alphabet, less one.
Has anyone made such a puzzle?

16 by 16 cells aren't "difficult" they are just rather time consuming. Give me a tricky 9 by 9 cells any day of the week!

I've seen 16 x 16 ones before. Intriguing the way they work - like hexadecimal:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F

They're much more time-consuming, but not necessarily harder

Haven't tried a 5x5 but I'll crank up the program and give it a go.

Get back to you on it.

Unless I'm doing something wrong, the program doesn't generate a 5x5 grid - I'm assuming that's 5 cells by 5 cells. It does 4x4 and 6x6 but not 5x5.

There can be no such thing as a sudoku of 5x5 cells, because there would be nowhere to put the thick lines. (5 being a prime number...)

If "normal" sudoku is 3x3, that means the small boxes are 3x3 cells, and the whole puzzle is 3x3 small boxes.

If a program generates a puzzle of 6x6 cells, that is 2x3 boxes each of 3x2 cells.

So 5x5 actually means 25x25 cells or truly massive.

Fair enough.

The largest I can get the program to go is 16x16 cells in either 2x8 or 8x2 or 16x16 boxes.
