    CalcuDoku clarification

    Filed under: General,Puzzle variants — djape @ 12:10 pm

    In order to avoid any further confusion with KenKen(R) and KenDoku(TM) trademarks of Nextoy, LLC, I have changed the name of these puzzles to CalcuDoku.

    This name is also used by other publishers but it is not trademarked.
