why suddenly i have 10+ tournament game when i just join for one tournament

[Xekura]

I join one tournament and 1 day later i have 10+ simutenous of "7 wonder duel" game.
Is there some kind of tournament that let you play more than 1 game at the same time?
the thing is i don't have time to finish them all and i lose my karma.


Thank
