Nice twist on the usual Sudoku

Always nice to find not-your-usual Sudoku. Overlapping boards force the use of inherently different logic.

Actually this is like a smaller version of the author's Samurai Sudoku with 5 overlapping boards. That anti-diagonal version is a real logic twister, one of my favorites, but I don't always have time to play a full game. This will be a great option for shorter games.

Note: the previous bug when using iPad in landscape mode has been fixed.

Latest update > fall 2016

My iPad will bring the game up in upright or landscape but in landscape the numbers don't work. You must have a bug you need to work out.
