Tic-Tac-Toe 5x

Everyone for sure knows this game where you have a 3x3 grid and your goal is to make a horizontal, vertical, or diagonal row of 3. The problem is when both players play well the game never ends. This version takes the idea a bit further; You need to make a row of 5 on a 15x15 grid and prevent your opponent from doing so faster than you.
