The reader is assumed to have basic knowledge of how to play Sudoku. To learn Sudoku,
you can visit sites such as
learn-sudoku.com,
or
sudokuessentials.com
This site offers
practice sessions for some elementary Sudoku skills, such as recognizing
Hidden Singles, Naked Pairs, Hidden Pairs, Pointing Pairs,
Naked Triples and Hidden Triples.
Sudoku should be FUN! This site handles updating of the candidates,
all Naked Singles are solved automatically,
and it gives a hint for the next move so you know at least
what pattern to look for, and if it's in a box, row or column.
PLUS, it warns you when you made an error!
Use of this site is recommended for desk- and laptop-computers and tablets. It's usable on phones,
but the candidate hints get awfully tiny.
At the bottom of the Sudoku board you'll find the hint for the next move.
You can use the buttons above the Sudoku board to enter a number
for a square or delete a candidate hint, OR you can use
the keyboard digit and delete keys.
