Form teams of two or three. There must be an even number of teams.
A bit of a game…
Each slide contains two problems. The team that finishes first gets a
point. Each problem solved correctly gives you a point.
Winning a matchup allows you to move one step closer to the couch.
Win enough, and the couch and everlasting glory will be yours!
