(4) If you press HINT a third time, only
the correct sequence is demonstrated.

(1) Press HINT, and an “H” suggests
the place for your next entry.
(2) You may press HINT again for a
more explicit clue, for example:
A single sequence “blinks”
This shows that the sum can be completed
by placing the correct number.
Two sequences “blink”, with zeroes in the
vacant squares
This indicates that there is only one
number which both sequences require.
(3) If you press HINT a third time,
the correct number is inserted into
the H square.

The hints work like this:
(1) Press HINT, and an “H” suggests
the place for the next number.
(2) You may press HINT again to see
the computerʼs logic for deducing
this number.
(3) Pressing Hint again will display
further steps in the logic.
(4) A fi nal press on HINT inserts the
correct number into the H square.
Eight different numbers “blinking”
The ninth number must be placed in the
H square.
“H” and zeroes, with a “blinking” number
The “blinking” number cannot be placed
in any of the “0” squares and must
therefore be placed in the “H” square.
Here none of the “0” squares can contain
a 3, as this would “clash” with a 3 in the
same “box”. Therefore the “H” square
is the only place for a 3 in the leftmost
column.
“H” and zeroes (but no other numbers)
“blinking”
This indicates that one number has been
eliminated as a candidate for the “0”
squares – and must therefore go in the
“H” square.

: If a press on HINT produces
“blinking” question marks in all the
vacant squares, this means that the
computer cannot give a valid hint because
of an earlier mistake – you have placed
a number in a wrong (though “legal”)
square.
10 FUNCTIONS OF THE KEYS
SUMMARIZED
ON/OFF
Switches the machine on or off. When
off, it still remembers the current puzzle
or game. If inactive for 81⁄2 minutes, it
switches off automatically.
LEGAL
In Su Doku, after LEGAL is pressed, the
bottom line shows all numbers that may
legally be placed in the current cursor
location. To switch this feature off, re-
press LEGAL.
