JC's program can solve rokudoku. But he has (with good reasons) not implemented chainy steps.

To take it go to new grid, gridsize 6, gridkind other, ok. And then use Design -> New Jigsaw Block or Nonet to define the 3x2 boxes.

FYI In JSudoku, you don't need to desing jigsaw blocks by hand for rectangular blocks. If you choose a Sudoku grid kind, JSudoku will create them itself. For a grid size of 6, it will create all 6 rectangular 3x2 blocks.(wider then higher). If you want 2x3, you can then choose Design -> Transpose.
It works for other sizes also. eg 10 = 2x5, 12 = 3x4... Not for sizes with are prime numbers of course !

Code: Select all
`. 1 2 | . 5 . 3 . 5 | 1 . 2 ------+------. . 1 | . . . . . . | 2 . . ------+------1 . 3 | 5 . 6 . 5 . | 3 . .`

It has 7.1 by using SE.
And it also has a X-wing.
There are still some number can be deleted.
The "1" and "2" at R1,
The "5" and "1" at R2,
The "5" at R5,
but I don't try what is this puzzle's minimum grid yet.
