Idea: NCAA Price Is Right.
Half the audience is students from one school – say, UCLA – and half is students from another school – UW.
Contestants' row is an alternating split – UCLA student, UW student, UCLA student, UW student. Contestants that advance on stage are replaced with students from the same school to maintain the split.
The school with the larger cash and prize total at the end wins, so a school could not participate in the showcase round and still win.
31 conference Price Is Right champions advance to a championship tournament, and all the schools that placed second compete in Plinko for the 32nd spot.
Idea: A USA basketball tournament in which each state fields a team.
