The New Sudoku Players' Forum

[urhegyi]

I'm collecting sudoku's in my database which fullfill the next criteria: solvable only by basics (Naked + hidden subsets(pair,triple,quad),Locked candidates(pointing/claiming)),x-wings, swordfishes, yellyfishes, xy-wings, xyz-wings.(limited to these). In the today's pattern game I found thisone I can add to my collection. If someone has similar examples feal free to post them.

Code: Select all

1.2.3.....4...5...5..6..7....84..5..3.......1.9.....8...79..4.......1..7....5..3.

It's a very extreme one, but a pretty good example. I needed all of the techniques I described before to solve it, but I'm also interested in other solutions.

A lot of mine meet this criteria. Most of these require fish of some variety, I've also noted which ones use hidden or naked quads.

Tatooine Sunset (fish)
That's No Moon (fish, has quads)
Tatooine Sunrise (swordfish)
Sun, Moon, and Star (fish, has quads)
22 (Clues) / 7 (Rows) (x-wing + xy-wing)
Tatooine Dunes (fish + xy-wing)
Mr. Ray's Wild Ride (jellyfish, has quads)
Totes Jelly (jellyfish)
Phone Home (fish, has quads)
Tatooine Krayt Dragon (swordfish + xyz-wing)
Q is for Quad (fish, has quads)
22 (Clues) / 7 (Columns) (xy-wing)
Chain Links (fish, has quads)
Tatooine Double Noon (swordfish + xyz-wing)

This puzzle:

Code: Select all

1.2.3.....4...5...5..6..7....84..5..3.......1.9.....8...79..4.......1..7....5..3. ED=5.2/3.8/3.8


is interesting because it's SE solution uses all these techniques:

Code: Select all

x Hidden Single (1.2), Naked Single (2.3)
x Pointing (2.6), Claiming (2.8)
x Naked Pair (3.0), Hidden Pair (3.4)
x X-Wing (3.2), Swordfish (3.8), Jellyfish (5.2)
x XY-Wing (4.2), XYZ-Wing (4.4)


It does not use any of:

Code: Select all

- Naked Triplet (3.6), Hidden Triplet (4.0)
- Naked Quad (5.0), Hidden Quad (5.4)


In the Patterns Game, I (and the other players as well) generate these puzzles (same pattern) in the millions! We tend to be looking for high-rated puzzles and diamonds!! Rarely interested in the solving techniques used!!! There might exist a puzzle that ticks all the boxes - uses all the techniques listed!

[mith]

I have one that I've yet to post that has all sizes of fish, hidden subsets, and naked subsets. Haven't really been looking for those in combination with other techniques though.

Numbers on the end are: patterns game number, puzzle number with the game, and puzzle SE rating.
I think all the high-rated (greater than 5.2) are not elligible for the db!!

[mith]

Here's one with 14, according to SE; Hodoku skips the X-Wing and XYZ-Wing though.

Code: Select all

..............1.23..4.5.6....2.1.7...1...35825..........6.7.....2...9....3...8.19  ED=5.4/3.4/2.6

The other one I have with all the fish and subsets (mentioned above) doesn't have an XY-Wing, XYZ-Wing, or Claiming.
