- Board: 12 photos at once and 90 s. Type the answers in any order, and a streak of hits gives you a combo.
- Sprint: one question at a time and 60 s on the clock. Stuck? Pass, but a pass costs 3 s.
- With friends online: a race on a shared board, a chess-clock duel or a territory war like in The Floor. Small typos are forgiven, and you can also answer by voice.
