I decided to either add or rewrite certain rules in tic tak toe.

1. Game one- Every alternate turn you must play for your opponent. This forces you to not only think of the best move for yourself but also the worst move for your opponent.

2. Game two- Both players get two moves per turn. This creates a game in which two way wins become easier to do but also become block-able allowing for the dreaded three way win without a complete collaboration between you and your opponent.

3. Game three- In the event of a tie a coin will be flipped three times. The winner of each flip will be allowed to change 1 symbol to theirs. 1 symbol change per flip win.

4. Game four- Each game and player can call for one flip in which he exchanges the two symbols that correspond with each other in relevance to the center space.

5. Game five- In the event of a tie. The player who went second or O will decide which edges of the 3×3 square will get a an extra row and column making it a 4×4 square. If there is still a tie it will be come 5×5 and X will choose the edges.
