The New Sudoku Players' Forum

This is mostly an Excercise for Large grid generators here & a good opportunity for DLX to show how it handles big grids.

It is simply a large grid sudoku variant: An 81*81 Sudoku with the usual 81 Rows, 81 Columns & 81 9*9 boxes. 81 clues (0-80)

This would now go one step further.

Each of the 9*9 boxes has 9 mini rows, 9 mini columns & 9 3*3 boxes (similar to vanilla)
Each mini box, row & column should have 9 different (MOD 9) values of its clues (0-8) making it a vanilla sudoku.
So you end up with a giant 81*81 sudoku that has 9 vanilla sudokus as well!!

Visually this can be appreciated if the (MOD 9) is added to the clue (so 9 becomes 9-0 and 80 becomes 80-8)
Or even better: Divide the 81 clues which are sorted incrementally into 9 groups of 9s (1-9). the group number is multiplied by 10 adding to it the MOD 9 value+1
( so 0 becomes 11, 8 becomes 19, 9 is 21 & 80 is 99). You end up with 81 different clues (11-99) replacing (0-80)

This is what the the 1st (top left) 9*9 box would look like in an MC grid
I've also extended the 1st line slightly to show more than just the 1st 9 cells for demonstration reasons

Code: Select all

11 12 13 14 15 16 17 18 19 21 22 23 24 25 26 27 28 29 31 ... 99
24 25 26 27 28 29 21 22 23         
37 38 39 31 32 33 34 35 36         
42 41 44 43 46 45 48 49 47         
53 56 55 58 59 57 52 51 54         
68 69 67 62 61 64 63 66 65         
75 73 71 76 74 72 79 77 78         
86 84 82 89 87 88 85 83 81         
99 97 98 95 93 91 96 94 92

Has this been attempted/done before ???

This also can be tested on any grid that has a line length which is the 4th Power of an integer (16*16 , 81*81 & 256*256)
16*16 should be a good starting point before expansion

I'm currently working on the 16*16 version of this puzzle.
Because the 16 symbols are broken into 2 sets of 4 symbols ... It reminded me of the Setdoku.
This variant works as a multiple-in-one puzzle similar to Setdoku

You need a very special 16x16 sudoku grid. The 16 symbols are broken into 2 sets of 4 symbols:
(Symbol/4) & (Symbol Mod 4) ... You can give each set of symbols a different colour to make it more appealing.

you have 16 Rows, 16 Columns & 16 boxes to fill using 16 symbols using the sudoku rules
Each Box is now a 4*4 sudoku puzzle using the 4 symbols created from breaking down the original symbols
Because you have 2 sets of 4 symbols, then each Box has 2 4*4 Sudokus.

I think I managed to create an example

Here is the Special Grid

Code: Select all

1 6 B G  2 5 C F  3 8 9 E  4 7 A D 
C F 2 5  B G 1 6  A D 4 7  9 E 3 8

Here is the same Grid with Symbol/4, notice that each 4*4 box fulfils the sudoku rules for a 4*4 sudoku puzzle:

43 34 21 12  44 33 22 11  41 32 23 14  42 31 24 13

As you can see the combination gives back the 16 symbols in a different format.

This one probably can be used to create puzzles that do not require a conversion table.

What do you think ?
for N=2 you have a 16*16 puzzle with each box having a 4*4 puzzle
for N=3 you have a 81*81 puzzle with each box having a 9*9 puzzle
for N=4 you have a 256*256 puzzle with each box having a 16*16 puzzles (which could have 4*4 puzzles in it as well, a "Sudoku^3")

[simon_blow_snow]

tarek, you can feel free to use my scheme of 81 coloured symbols from this post for your 81x81 version. Should make a very pretty grid.

As for the 16x16 version, I have this scheme:

Code: Select all

Each symbol is a colour-filled square, with possible "+" or "X" inside.

So we have 4 binary attributes:

with "+" or without "+"
with "X" or without "X"
outline: blue or red
filling: green or yellow


When I have time I will try to make some graphics for your latest puzzles.

As for the 256x256 version, it takes more thoughts to create 4 different 4-way attributes which are simple and elegant enough.



For the 16x16 version, is it possible to make a solution grid which has the property "neighbours all have different attributes"?

[tarek]

Thanks simon_blow_snow. For the 16x16, they should be 2 4-way attributes ex. 4 shapes and 4 fillings.
For the 81x81 they should be 2 9-way attributes not 4 3-way attributes. They 81 symbols however will be much better than the 1-81 number representation, thanks

[simon_blow_snow]

For the 16x16, they should be 2 4-way attributes ex. 4 shapes and 4 fillings.
For the 81x81 they should be 2 9-way attributes not 4 3-way attributes.

If you consider the two shape attributes as a single attribute and the two colour attributes as another then you will have two 4/9-way attributes. These schemes still work if you ignore the inter-relationship between the shape/colour attributes (for example, red-out-yellow-in and red-out-green-in both share the same outline colour, but can be considered completely different attributes).

However, what I proposed in the previous post was perhaps closer to "Setdoku^2", i.e. all individual 4x4 boxes in the 16x16 scenario are Setdoku grids themselves. For the 256x256 scenario, if ever we can work out a scheme of 16 (!) different binary attributes, we can have 256 16x16 boxes which are all valid Setdoku^2 grids, i.e. the 256x256 grid would be a "Setdoku^4" grid!

[tarek]

You are correct when saying that combining two features will give us 2 4-way attributes and therefore solving the problem. You are also right when saying that these are better suited for Setdoku. I think that for the specific case of of 16x16 sudoku^2, a simpler 2 4-way attributes are better suited. They can be as simple as a hollow square, diamond, circle and triangle as symbols for subpuzzle 1 with smaller solid similar shapes that fit into the larger hollow shapes for sunpuzzle 2. No colours needed, so it can printed as balck and white.

For that 256x256 sudoku^3 we will need your construct to make it more visually appealing.

Tarek

[tarek]

I've done some work with image processor yesterday & I think that the results are acceptable. They are not as well designed as simon_blow_snow's symbols for setdoku but should be simple enough to allow for manual solving on a 16x16 puzzle.

this is the same puzzle mentioned a few posts earlier, any suggestions, comments are appreciated



enjoy,

I've programmed a modified version of my solver to accommodate this variant & will be posting a walkthrough for puzzle02. There has been little response regarding this variant & my feeling is that the the number of fans of this variant is just 1 (myself ).
