what about this? for example, every sunday there can be a tournament for every level of players
from 1-10= 1st : 10000 credits 2nd: 5000 credits and 3rd: 2000 credits reward
from lvl 20-30= 20000 credits 2nd: 10000 credits and 3rd: 5000 credits.
etc...it would be more good if there would be an exp reward with credits (1st place will give you much credits and enough xp to lvl up..)
choose you the reward or tell me what you think about this..

oh, and what about a chat to talk with players?

Hi, 1159690469!

I like the idea of tournaments, but there are some aspects that would be tricky.

This is the biggest problem: would you have Level 21 players fighting Level 29 players? What would you do to give the lower-level player a fighting chance? The lower-level player currently goes first, which helps with a level disparity of two or three, but if the difference is eight, it's a bigger problem.

Some other things should probably be tweaked. Connection issues? Maybe relax the countdown timer.

What about when you're waiting for your next opponent to finish a long match? What do you do in the interim?

you would need to do something about the level hierarchy wouldn't you. how about a tournament for every 3 levels?
