Qi is the number of games you have played. There is a qi limit of 100 games per day. Anything else need answering?

just for future reference place these kind of questions in the rapid thread section.

I played about 120 games on monday.
@Skylarrr, I don't see a limit.

You can play as many games as you'd like
You're qi only goes up 100 games a day, then stops.
That doesn't mean you can't play anymore.

That makes sense, thanks!

Another thought, Is it possible for me to rank up after i've done my 100 Qi for the day? Will it continue to say "121 more games to black belt", "120 games to black belt" etc?

No, that is what the Qi is. After you hit the 100 limit, it will continue to say "X games until xx Belt" until the time resets.

EDIT: Ninja'd, Fee.

No, when you hit the cap you stop gaining Qi, when you stop gaining Qi you stop moving closer to your next belt.

Alright, it all makes sense now. Thanks!
