All the rules are same as in Tic Tac Toe but instead of making 3 O's or 3 X's we have to place the numbers such that the total is 15.

The Catch is that one player will have only odd numbers - 1,3,5,7,9.

The other player will have only even numbers - 0,2,4,6,8.

The turns keep rotating but the odd and even starting level is random. The first person to complete a line that adds upto 15 is the winner. The line can have both odd and even numbers.
