Trividoku: where Trivia and Sudoku combine. Each of the 101 puzzles in Trividoku challenge you with nine or more Trivia matches. When you know the match, you can now fill in an additional digit in the Sudoku puzzle. Most puzzles can be solved even if you don't know the Trivia, by just using Sudoku rules, but a few of the harder ones have as few as two digits given - you have to discover the rest by solving the Trivia. Whether you're a Sudoku fan or Trivia buff (or both) you'll love Trividoku. This second edition also contains bonus Sudoku Islands, Sudoku Earthquake and Stars & Stripes Sudoku puzzles.
