GridClash turns lesson review into a projector quiz show

Field notes

The setup can start from typed questions, a spreadsheet, a ready-made example board, or uploaded teaching material. During play, the teacher reads questions and awards points while the site handles turns, timing, and scores. The page says generated questions are sorted by difficulty across point values and can be edited, reordered, or replaced before class; it also describes optional custom power-up rules and wheel outcomes.
