1. As you can see - both of us have five pieces on the board. Whenever you win an omok match, there's a 2-5 second delay before it'll register your win. During that delay, the other player can quickly place a piece and land 5 in a row, therefore, giving him the win as well. I had a good laugh for about 5 minutes, but I can see this causing some issues for serious omok players. *Note: Delay remains consistent (with or without server lag)
The weird delay with omok can cause other problems too. If you click an omok window to join, but then the host closes it within like 3 seconds, the person trying to join will d/c.
