Animal Sudoku

Afraid of numbers but not animals? Try Animal Sudoku!!!

This is a regular Sudoku Puzzle with a twist. Instead of numbers 1 through 9, nine different animal icons are used in place. We call this Animal Sudoku. This is the default mode. However, one can always switch to regular Sudoku Puzzle with numbers. Switching resets the puzzle. The number of blanks can be set to any number between 30 and 50, the higher the number of blanks the harder the puzzle is to solve. There are no hints in the regular Sudoku Puzzle with numbers. However, there will be hints in Animal Sudoku. If you click a blank in the puzzle, you will see what can go there in the bottom. If there is only one possibility, you can double click the blank space to fill it up. In the number version, you can move from blank to blank by using the left/right, up/down arrow.
