Nintendo Sodoku Gridmaster Instruction Booklet page 6

PLAY SCREEN CONTROLS
Rules and Basic Controls The rules are exactly the same as
traditional Sudoku. These rules are outlined on pages 16 and 17. (Please
refer to them as needed.) According to the rules, one must deduce a
number to be placed in an empty cell. To enter a number, touch the
desired cell, then touch the number you want to input.
Using Options While solving a puzzle, you may have several possible
numbers for a single cell. You can input up to four small numbers inside a
cell as a note to yourself. These are called options, and you can enter
them into the four corners of a cell using the options panel.
Options and Quick Save In addition to solving puzzles, you can also
change settings and save your progress in a puzzle that you want to
continue later. For more information, please see the information on pages
12 and 13.
!
Guidelines are areas highlighted in orange. They are always centered around the cursor.
The column, row, and 3x3 block around the cursor will be highlighted.
You can toggle the Guidelines on and off by using the L or R Buttons.
TIP
If you touch a number within a puzzle twice, all other cells with the same
number will be highlighted. This is a useful tool for solving puzzles!
