Ahh right.
So there's not that much participation during the tournament but that's still a good start for them.
Maybe they need to make a louder noise next time if they will make another so that more participants will be interested on this event they'll make.
It's worth noting that the larger the prize pool in such free tournaments, the more likely it is that it will attract the attention of more users. Although for those who participate, it's better to have less competition in the tournament, because in this case, it's easier to accumulate chips and compete for prizes in the final stage of the tournament.
