Minigames ex. omok and cards

minigames like omok and card matching would be fun and sell them for like 20mil in summoning rock?

I agree with this idea, sometimes when you get bored enough, you'd like to play a game of Omok, it can also add into future events such as holding tournaments.

or maybe can add into gpq ??

Have the boxes drop Match Card and Omok Sets? I assume that would work, just don't make it that easy to obtain them.
