Sudoku Tanto
Solve a Sudoku Tanto puzzle in the same way as you would solve a standard Sudoku puzzle.
The numbers 1 to 9 must appear once in every row, column & box of 9. The difference in a Sudoku Tanto is that the shaded cells show the locations of all the even numbers (2, 4, 6 & 8).

Try your hand at solving the Sudoku Tanto puzzles on this page.If you have Microsoft Excel, you can save this webpage and open it in Excel (Save it as HTML only NOT Webpage complete then open the html file in Excel). Alternatively, if you click on the orange button below the puzzles, you can get a printable copy of the puzzles in pdf format. If you are unable to open the pdf file you can download the free Adobe reader by following the link below the puzzles.

There will be a new set of Sudoku Tanto puzzles next week. The solutions to this week's puzzles will also appear on this site at the same time.
This page displays well in Microsoft Internet Explorer & Opera. If you are using the Mozilla Firefox browser, some of the grid lines in the puzzles may not appear. Refreshing the page may solve the problem. If not, the problem can usually be resolved by selecting - View, Page Style, No Style then - View, Page Style, Basic Page Style.
Alternatively you can use another browser or select the printable version.
Neither Apple Safari nor Google Chrome display the grid lines correctly and I do not, therefore, recommend using either of these browsers.
