Hump Daaaaaaay!

Dodge the weather and spend some time with your friends playing Dodgeball on Wednesdays! 
This is an action-packed league that is a great way to break up the week, and have some old school FUN with your friends, co-workers, or family.
Its all going down starting in the New Year.

FunCorp - Corporate Events Powered by Underdog

Can we help with "friend building" and your company culture?

Let's start planning today!



Signing Up As An Individual?

Signing Up As An Individual?

Here's what you need to know!

Underdog is a great way to meet new people if you've just moved to town or are looking for something new to do. When you register as an Indivdual or "Indy" your name is put on a list and when enough people register we make an "Individual Team" and introduce you to a whole group of new people.


Have another friend or two who want to play with you as well?  No problem.  In your signup there will be a spot to enter their name(s) so that we can place you all on the same Individual Team. Also, be on the lookout for our Indy Parties - another great way to meet and socialize with people!


Check out our Indy Rundown Page for more info and upcoming leagues!
