My friend and I created a new way to play Sudoku and we humbly believe that our 2 x 2 is the hardest Sudoku puzzle ever, our game is called SUDOKUit. I know you are saying that in the real world any Sudoku player worth their salt can solve a 2 x 2 Sudoku in seconds, with their eyes closed. Our 2 x 2 SUDOKUit puzzle can also be solved in seconds but at the fourth level it is so difficult that most skilled players will find themselves hitting the Hint button for clues. A solved 2 x 2 SUDOKUit puzzle like a traditional Sudoku has the numbers 1 to 4 in each row, each column and each 2 x 2 grid. To solve our 2 x 2 SUDOKUit puzzle you need to use forward thinking skills like you use in Sudoku and chess but you will have to dig much deeper. At the 6th level, Insane, we believe it to be The World’s Hardest Sudoku Puzzle. Our 3 x 3 SUDOKUit puzzle is another story, at the higher levels it is so hard that most expert Sudoku players might not be able to solve it.
Here’s were we are with the game. We finished testing the SUDOKUit program and are finishing the final interface plus adding a few helpful features. SUDOKUit will always be free to all and can also be downloaded to your smart phone and tablet. Feel free to comment but after you try to trash our claim be kind enough to return and let us know if you finally met your match. I will keep you posted when you can try your first SUDOKUit 2 x 2 and 3 x 3 puzzle.
