Anyone can play SUDDO at any time - no need for a mobile or a tablet - just a pencil and a bit of paper and you're ready to go!
Draw a nine by nine grid. Place six different numbers in the middle row and six in the middle column. Blank out the columns either side of the middle column and the rows above and below the middle row and begin playing.
You can play either a single player or two or four player game just like when you use a tablet or mobile.
It's probably best to use pencils so that you can erase numbers when you need to!
