Fast and Exciting!
Sixy Sudoku offer all the fun of regular sudoku, but without the time consuming hard work. Because only digits 1-6 are used, there is instant overview, making errors unlikely. The extra layer of logic makes you think quite hard, but even the toughest Sixys still take much less time than 9x9 sudoku!
We offer 10 books by Peter Ritmeester, both Regular and Wacky, ranging from very easy to very hard. And a free app with no less than 500 Sixys!
Publishers and Newspapers worldwide: You can publish Sixy Sudoku as well! Just contact Peter Ritmeester at PZZL.com, see button below.
