Suduku

Do you know the famous game Suduku? Even though it is a game that incorporates many numbers, it is not about math, we promise. It is actually a game about focus, observation skills and logic. Your goal is to fill out the empty spaces on the board by ensuring you have all the numbers from 1 to 9 in a straight line, both horizontally and vertically, but also in the squares. And each number can only appear once in each of these. So take note of the numbers which are already on the board and try to find what is missing. You are playing against the time so you will have to be fast in order to get a high score. Also, you are only allowed to make up to three mistakes, so try to be sure before writing a number down. You can also use a hint if you get stuck. Good luck!
