Sudoku Help - Sudoku Stripe

Here's a page from the extensive help system for SudokuDragon. It is displayed as a help screen when running the program. To get the full picture Download our Sudoku Dragon and see the screen in its full context.

Our Sudoku puzzles have a little extra twist. You can choose to add a stripe to any generated puzzle. All the daily puzzles and puzzles generated online have this feature too. One hidden group of squares in the grid (a row or column or region) has all the numbers in order (or reverse order).

This is provided as an generation option within the Sudoku Dragon program when you create a new puzzle. Here are some examples of puzzles with the conspicuous stripe shown.

Sudoku stripe 1 In this puzzle the stripe was hidden away in reverse order in the last column. The Sudoku stripe can be in normal or reverse order and in any row or column.

Sudoku stripe 2 The stripe can also be wrapped into a region or mini-grid. The top-central region had the numbers 1 to 9 hidden as a sequence. The pattern can also be found in reverse order in regions.

We think you'll enjoy solving our puzzles with the Sudoku stripe as it adds a new addition to your solution strategy. Finding where the stripe is located will generally unlock the solution to a number of grid squares. In more challenging puzzles it is often tricky to work out where the stripe is hudden.
