Class Gauntlet
A whole-class review game where one student takes on the rest of the class, and nobody gets knocked out.
Pick a question set (write your own, paste from a spreadsheet, or use the sample), put the game on the projector, and students join with a PIN. The class answers first, then a challenger answers alone with three lifelines: poll the class, ask two classmates to explain, or go with the class.
Students who miss a question join the Comeback Crew instead of sitting out, and the round ends with a Prize Pot for the challenger or the class. It’s free, runs in the browser, and needs no accounts.
