Game Desert Sudoku

Enjoy a Sudoku with a desert-based version. You have three levels of difficulty and a limited time to complete all grids on the board. The rules are always the same, you have to put a number in each box and you can not repeat a single number in the same row, in the same column or in the box of 9 boxes. You will have to think a little if you want to get it, a real challenge for both beginners and professionals.
