http://royals.ms/forum/threads/omok.7338/#post-35003 General consensus seems to be it's really hard and probably won't be coming soon. I hope to be proven wrong though; I love Match Cards.
This has been brought up numerous times before and seemingly, other things have taken priority. http://royals.ms/forum/threads/suggestion-omok-tables-card-tables.9313/ http://royals.ms/forum/threads/omok.7338/ http://royals.ms/forum/threads/suggestion-omok-forum-mini-game.11414/ http://royals.ms/forum/threads/suggestion-casey-game-npc-on-maple-island.11346/#post-58520
Unfortunately, that is pretty much the case: getting Omok/Match Cards to work properly would be tricky and we have a lot of other stuff that takes priority. This does not mean, however, that they won't be fixed, so don't give up hope. =)
