9plus12 game

This puzzle.....
Code: Select all
+---+---+---+
|...|5..|1..|
|.98|...|...|
|...|...|.4.|
+---+---+---+
|5..|123|.7.|
|...|456|...|
|...|789|...|
+---+---+---+
|...|...|2.9|
|1..|3..|...|
|...|...|8..|
+---+---+---+


has 9 clues in box 5 and a valid puzzle is produced by adding just 12 more clues.

A little thought will show that each of these puzzles has 6^6 * 2 isomorphic equivalents with the minlex box5.

Thus the search space could be less than it would otherwise appear.

Probably very few essentially different < 100 ? of these puzzles

I am not sure which is the best way to canonicalize these puzzles for reference purposes. ?

Also , potentially there could be a "9plus13" or "9plus14" puzzle which is superhard.

Anyhow, whilst the patterns game is regrouping - perhaps you can find one ?

Bands 1 & 3 and stacks 1 & 3 can be swapped too, so wouldn't that be 6^6 * 2^3 ?

Your puzzle is SE=6.7. The best I could do with a quick run was some "9plus14"s, of which the hardest was:
Code: Select all
 1 . . . . . 2 3 .
 . 4 . 5 . 6 . . .
 . . . . . . . . .
 . . . 4 7 5 . . 8
 . . . 6 2 9 . . .
 2 . . 3 1 8 . . .
 . 6 4 . . . . . .
 . 8 . . . . 7 1 .
 . . . . . . 9 . .   ED=8.9/1.2/1.2

Hardly 'superhard', I'm afraid.

Here are the minlex morphs of 3 more "9plus12" puzzles [including the first example]

Ive attributed them to gfroyle as they are derived from 4 of the 17-puzzles with 5 clues in a box

but there are more to be found

indeed the isomorphs do have a furthur 2^2 ways ........ well pointed out.

so we probably should really be able to find them all then - given that there are so many isomorphs of the same puzzle with the same box5.

I might have to reconsider the possibility that there will be a superhard puzzle with a full box 5. Bivalues are difficult to prevent.

Although mauricio gave us this
Code: Select all
+---+---+---+
|6..|..2|.59|
|52.|.4.|.1.|
|..3|5..|2..|

|3..|194|5..|

Funny, if I take away a random set of redundant clues, meaning the puzzle is no longer a diamond (pearl?), I get
Code: Select all
 6 . . . . . . 5 9
 5 2 . . 4 . . 1 .
 . . 3 . . . 2 . .
 . . . 1 9 4 5 . .

 7 . . . . . . . 8   ED=11.2/1.2/1.2, 30 clues

Maybe the 11.0 came from an old version of SE.

Here are some (not very exciting) "9plus13"s, based on over 3000 '4 in a box' puzzles in Gordon's file, for the record:

Just to show that a "9plus12" is possible without having a 17 in it.
Here is a sparse example
Code: Select all
+---+---+---+
|..7|3..|1..|
|8..|...|4..|
|5.9|...|...|
+---+---+---+
|.6.|123|...|
|...|456|...|
|...|789|...|
+---+---+---+
|.1.|...|...|
|...|...|.9.|
|...|...|.58|
+---+---+---+  #05


And yes mauricio's puzzle is 11.2

Actually the previous puzzle shows that 8 clues can be added to make a valid puzzle to two complete boxes [B1and B5].
Code: Select all
+---+---+---+
|647|3..|1..|
|831|...|4..|
|529|...|...|

|...|456|...|
|...|789|...|
+---+---+---+
|.1.|...|...|
|...|...|.9.|
|...|...|.58|
+---+---+---+


We do know that 3 clues can be added to make a valid puzzle with 3 complete boxes [B1,B5,B9]

Here are 55 more 9plus12s.

Fairly unspectacular puzzles, derived from a [surprisingly] still expanding collection of 9plus13s [400,000 of them]

Despite the number of isomorphic ways to represent a puzzle with a full central box - I am still surprized at the increasing number of different puzzles there are.... [9plus13, 9plus14.......... etc]

However it probably stops around the 9plus25 mark, a quick look i found this one.
Code: Select all
+---+---+---+
|...|...|3..|
|6..|5.8|.4.|
|..7|.34|.6.|
+---+---+---+
|...|123|.9.|
|1.9|456|..3|
|3.5|789|...|
+---+---+---+
|9.6|8.7|...|
|7.1|..5|.86|
|...|...|..9|
+---+---+---+

those extra 25 clues are all essential.
and that perhaps induces a 9plus26 game - if anyone were interested.......

given that every true minimal puzzle can have 9 ways to fill a box
and several ways to remove unnessesary clues

thats a lot of puzzles..... but i suppose i new that already.

edit - on return from pub.........
well a rough guess of the number of different puzzles would be
9 * 5e9 * 30^8 ~ 3e22

30 might be the average number of ways you can remove clues from a single box

 . . . 3 . . . . .                  ED=7.3/1.2/1.2
  No. fixed: 36 (= 9plus27)

Re: 9plus12 game

Thanks for that.I cheated of course, because i took a 39 puzzle, filled up a suitable box and deleted clues to minimality.

And extended to a 9plus28.
Code: Select all
+---+---+---+
|..2|...|...|
|8..|..2|...|
|95.|.6.|...|
+---+---+---+
|4..|123|.9.|
|1..|456|7..|
|.25|789|41.|
+---+---+---+
|2.1|698|54.|
|.4.|.1.|...|
|.98|2.4|1..|
+---+---+---+


in any one grid there are very many puzzles.

it would appear that 9plus12s are rarer than minmal 17 puzzles.
