What were your problems and how did i fix the bugs:

As there are 5 scenarios for the player to win,I had to think about how to determining if the player has won. For now, I have simply checked the status of the board for all 5 scenarios.
To prevent the pointer from going out of list, I simply checked and set a minimum and maximum to the pointer range.

My obstacles:

Understanding the logic behind the game.

Tips to the aspiring coders out there:

Write the program structure out before you start
Use print statements to check your program and fix bugs
