1.7 utilizes 34 different solving techniques. They are:
Finned Fish (finned X-Wing)
2 String Kite
Empty Rectangle (or Hinge)
Colors (Conjugate Pair Coloring) (fixed this, wasn't working
prior to version 1.7) Now just press the Z key!
Uniqueness Test (only available on valid puzzles)
* new for version 1.4
- Unique Corner
- Unique Side
- Hidden Rectangle
- Unique Rectangle type 4
Jet Sudoku also uses BRUTE FORCE but
I don't consider that a valid solving technique. BRUTE FORCE is only
used to prove validity
when the above techniques fail to produce a solution.
There are lots of other advanced solving techniques out there.
Jet Sudoku version 1.4 doesn't use them but perhaps future
versions will. I have experimented
with many other advanced techniques. Many are either redundant or
too complex (for me anyway).
Several of the above techniques are obsolete or at least redundant.
When using the default order of
solving techniques, I've yet to find a puzzle
that requires finding a Squirmbag, X-loop, or COLORS technique to
produce a solution. If you find such a puzzle, please send
it to me!
I will probably be adding more solving techniques in the future.
I you have any suggestions please contact me at firstname.lastname@example.org
