Grid goes here     


New this issue

Version 109

Allows you to save a game (in memory, not disc) and recall it. There are 4 save locations

Version 108
Puts back the error checking and turns faulty cells blue

Version 106
This allows you to input puzzles (press "Clear puzzle" first) and help it along as in earlier versions.
The solve button tries everything in one go until it solves the puzzle or gets stuck.
It can solve all the puzzles here except X1 and X2 (the "extreme" puzzles)

With X1, it works if you 'Solve' then change the 25 in the bottom right to a 5!

By hand, after 'Solve', I've tried the previous "trio" rule. The top left box has only got 5 in its middle row, therefore the other 5s can go from the second top row. I tried this through the whole puzzle. It removed a good few digits, but didn't find a solution! It obviously needs a different type of rule to solve it. If you can solve it, please let me know what you did - and why.
