Examples Of "Hint" Displays - Millenium PowerBrain SUDOKU EXPERT Manual De Instrucciones

If the HINT button is held down for 2 seconds, the machine solves the complete
puzzle step by step. A press on any button speeds up the solution process.

EXAMPLES OF "HINT" DISPLAYS

These examples illustrate how the machine demonstrates its logic for deducing
a number. (Characters printed here in bold are "flashing" on the display. In the
diagrams in examples 3 the letters at the edges of the grid provide a "grid
reference" to identify the cells.)
Sometimes there will be different ways of coming to the same logical conclusion
about which number should be in a particular cell. If you can see a logic that is
different from the one demonstrated by the machine, do not worry unless you
have come to a different conclusion (in which case you will have made a
mistake in your logic).
When solving one of the more difficult puzzles you might not always understand
the machine's explanation. In such cases look carefully at each stage of the
explanation as the machine attempts to lead you through the logical process,
and study the numbers and 0s that are flashing. As you become more skilled at
Su Doku you will find it easier to understand these more advanced
explanations.
For a puzzle on a high level, you may need to use the "hint" feature several
times. If so, remember that parts of the logical process for deducing one
number may also help towards deducing a number in a different cell.
So if you have carefully followed the process for one hint, this may also help
you to understand the next hint.

9 1
9 1 2
4 5
3 4 2 9
7
5 8 7
8 H 1 9 2 4
The H flashes together with the numbers in the bottom
4
row and the bottom left block (1-6 and 8-9), showing
that none of these numbers can be placed in the H cell.
4
1 9 So you know that the only legal number for this cell is
7.
