Built for three rooms

One PIN. Three very different rooms.

A 5th-grade review, a 1,000-person lecture, and Monday's all-hands don't share a lot, except they all work better when people compete. Gumbalup is tuned for each.

Built with and a lot of snacks, by two humans who really want the room to shout.

One dreams it up, another writes the code. Both refuse to ship boring.
