Sudoku Notes Feature

1.Players can now place multiple numbers in the same box as ‘placeholders’ until ultimately deciding which number should remain in the box through logical elimination.

2.To activate the NOTES feature, touch the N icon at the top of the screen with the stylus. Touch the number at the bottom of the screen you wish to select and then touch the box within the grid to place it. The black triangle in the corner of the box will flash to symbolize that this is now an activated ‘NOTES’ box.

NOTE: You must touch the N icon each time you select a NOTES number to be entered.

3.To add another number to the box, touch the N icon with the stylus again, then one of the numbers 1-9 at the bottom of the screen and add it to the box. The player can add as many NOTES numbers to the same box as they like. To show all the placeholder numbers within each box, each NOTES number remains onscreen for 2 seconds and then changes to the next NOTES number.

4.For example, if a 7 and a 4 are placed in the box, 7 would remain onscreen for 2 seconds and then would become a 4. The 4 remains onscreen for 2 seconds and then changes back into a 7.

5.This cycle continues until the numbers are finalized. To finalize the number, select the number from the bottom of the screen and touch the square again. If correct, the number is accepted, the black triangle in the corner disappears, and the other NOTES numbers disappear. If incorrect, the finalized number will flash in Beginner Mode.

logical constraints of the puzzle.

• If you touch DONE with the stylus, you can play the puzzle you just entered on your Sudoku unit.Touch ANS

anytime during game play with the stylus to view a five-second flashing hint of the solution.

• If you touch ANS with the stylus, you can view the completed Sudoku puzzle.

Please note that this game is based on puzzles which have only one solution. Thus, there may be times toward the end of a puzzle where two different options for placing numbers are technically acceptable, but only one version is accepted as being correct by this handheld game.

Due to the varying reliability of Sudoku puzzle sources, there is a remote possibility that the Sudoku Solver will be unable to solve the inputted puzzle.

6.To CLEAR an entry, touch the C at the top of the screen and then touch the box on the grid to be cleared. A new number can now be entered in that box using the same steps as above. You can also directly place a new number in a filled box without clearing the previous number by touching a new number and then touching the box.

7.Once each of the numbers 1 through 9 has been placed correctly, the number will disappear from the bottom of the screen. If the numbers have all been placed correctly, a sound effect will be heard. If no sound effect is heard then one or more numbers have been placed incorrectly.
