Heading into its final day, the WIAA says it has already reached its goal of 34,000 fans in attendance.
A big crowd of fans came from Kewaunee county Saturday afternoon for Algoma and Kewaunee title games.
The season finale for girls basketball teams brought more fans and more excitement.
"I'm excited, ready to go, I mean, we worked a long time to get there," Brenda Kleiman, a Kewaunee parent said.
WIAA officials says a few thousand more fans have showed up since Friday.
Fans filled seats of the Resch Center in Ashwaubenon to catch local match ups including schools from Green Bay, Kewaunee and Algoma.
"We're filling it up pretty good. It helps having two teams here from the same county, it's really cool," Austin Kassner, a Kewaunee high school student said.
No matter who they're rooting for team spirit was in full supply.
"Just cheering loud, making cheers up for them, having posters, dressing up, just supporting them as much as we can," Daniela Gomez, an Algoma high school student said.
"Like the hype's a lot higher than for boys, especially for Algoma. We're seriously all about Girls Basketball," an Algoma High school student said.
The WIAA says tournament attendance for the week could make the threshold of 40,000 fans.
"Going into today, we're around 36-thousand, so we've not only met our goal, we also haven't seen a decline, and now it's a matter of, you know, what kind of walk up might we get today," Deb Hauser, WIAA associate director said.
Both Algoma and Kewaunee schools won championship titles Saturday. Algoma beat Colfax, 46-30, in Division 4 and in a close Division 3 game Kewaunee shut out East Troy, 60-58.
