A Trividoku is a blend of Sudoku and Trivia. As with a regular Sudoku puzzle, you have a nine by nine grid of spaces. To solve the puzzle you need to fill in each space with a digit 1 - 9 so that each row, column and 3 x 3 box contains exactly one of each digit. Every puzzle also starts with about twenty "givens". These are the digits in the puzzle that help make it so that the puzzle can be filled in with a correct solution.

With a Trividoku, we take out nine of the given digits and replace them with Trivia matches from a variety of different topics.

Trividoku #1 and Trividoku #2 are available on

Sudoku Atlantis

Sudoku Atlantis takes you on an epic journey through over 100 Sudoku variations. The puzzles range from easy to hard as your narrator describes the last days of Atlantis. All puzzles are based on the 1-9 logic puzzles of a normal Sudoku, but each puzzle has some variation to it – islands floating in the sea, peaks and valleys where only certain digits can be placed, patches where the digits are taken from the puzzle for you to place back in. Find your way through the mystery of Atlantis as you solve the puzzles.

Sudoku Islands takes regular 9 x 9 and adds in the Island twist. Just like in a regular Sudoku puzzle, the digits 1 - 9 each appear exactly once in each row, column and 3 x 3 box. On top of each puzzle grid you’ll also see four “Islands” floating. Each Island also has 1 - 9 appearing uniquely in each of its nine grey squares.
