Version 1.13.1 (Oct 18th 2024)
The solver can now cope with Str8ts variants

• Str8ts B - Str8ts with 3x3x Sudoku boxes
• Str8ts X - Str8ts with diagonals that must be straights as well
• Str8ts BX - which combines both

I will add some examples when I've finished producing some stock. The variant can be triggered by selecting it from the new pulldown in the top left corner. Also links with type=B, type=X and type=BX parameters will work. I have changed the Weekly player to export this parameter to the solver.

Compartment Check is now highlighting the candidates removed rather than blanking them.

There were a number of strategies with small errors like the wrong cell names and these have been fixed.

Version 1.12.2 (July 22nd 2024)
Changed the [Take Step] to not pause if nothing is found on Compartment Check. Should speed up clicking through a puzzle in a similar way to the Sudoku solvers. Same number of click to get to any result.

I think I've got to the bottom of the pink message box. This is supposed to be an error handler but one of the error message strings was not being initialised and occasionally filled with a byte or two and false returned instead of the result.

Version 1.12 (July 6th 2024)
After some time I've given the Str8ts solver some love.

• Added packed strings for easy transportation of candidate information. The URL parameter ?brd= can accept the traditional 162 (clues+black/whites) string or the new 243 long packed string. There will be an article on this shortly.


• [Email this board] in a new popup with the packed string option.


• New [Import a Str8ts] button for str8ts import


• Cookie now uses the packed string


• Added a 'Candidates can be Edited / Highlighted / Coloured similar to the Sudoku solvers


• Preparation for Setti!

I have re-written this solver to bring it up-to-date with the
