* How To Play
  1. Fill in each square of the grid with one number.
  2. The numbers used to fill the squares may be 1 through the number of the grid size. In a 3x3 puzzle, use the numbers 1-3; in a 4x4 puzzle, use the numbers 1-4; and so on.
  3. Do not repeat numbers in any row or column.
  4. Each heavily outlined set of squares is called a "cage." The numbers in each cage must combine (in any order) to produce the target number indicated in the top corner by using the mathematical operation next to the target number.
  5. A number may be repeated within a cage as long as it is not in the same row or column.

* Controls
To enter numbers in the puzzle, use the 5-way to move the cursor to the target square and press a number key from the on-screen legend (keyboard numbers will also function):

To toggle between placing answers or notes in a square, press the center button on the 5-way (or press "N"). The cursor will change based on which entry mode is active.

To clear a square of all answers or notes, move the cursor to that square and press the "DEL" key.

* Advanced Controls
"Negative" notes (numbers that are certain not to be in a square) can also be used to help solve puzzles. To place a negative note, hold the SHIFT key and press the desired number. Negative notes are indicated with a "slash":

Note that squares can contain both positive and negative notes.

To copy and paste notes from one square to another, move the cursor to the "copy" square and press RETURN. Then, move the cursor to the "paste" square and press SPACE.

* Using Hints
There are 2 types of hints that can be used for any puzzle.

  1. REVEAL: Press the "L" key at any time to reveal an answer in a random empty square on the puzzle.
  2. CHECK: Press the "K" key at any time to check all the answers in the puzzle. Any incorrect answers will be marked with an X.

To earn a star for a puzzle, use 0 hints. During play, a star icon will be displayed in the upper right corner of the puzzle as long as no hints are used.

* General
Press the MENU button to access additional options for the game:

  1. CLEAR PUZZLE: Remove all answers and notes in the current puzzle.
  2. RESET DATA: This will erase all saved games and puzzles.
