Protect the Queens

Test your Problem Solving and IQ level while enjoying this game, based on the idea of N Queens problem. If you are not familiar with this problem then worry not. It's a simple Chess problem in which you have to place N number of Queens on an N x N chess board such that No Queen attacks any other queen. Feels Easy, Isn't it? e.g. if you select 10 queens as an initial number on the Playing Options screen which will be the N value, then you will get a 10 x 10 board and you would then have to place 10 queens on this board such that no queen attacks any other queen. Placing a queen on the board would give you 10 points. You can also take a hint from the game but it would cost you 10 points. If you want to Undo your move, you can also do that but that would result in subtraction of 12 points. Maximum points at any level could be N x 10.
