The big screen and the phones

Teams join by scanning the QR code or typing the game code, and pick a name and a picture.

Team leaders play from their phones.

Reveals show the right answer, the fastest team, points gained and who moved up.

Each team sees its result.

Every kind of question

• Multiple choice: two to six answers, one or several right, with pictures if you like.
• True or false: quick statements to keep the pace up.
• Typed answers: teams type; you judge on the big screen: full, half or no points, bonus or malus.
• Numbers: how many keys on a piano? The closest guess wins, or the closer the more points.
• Put in order: oldest first, biggest first; each item in place earns points.
• Several answers: title and artist, or five posters, each part judged on its own.
• Pin on a picture: maps, floor plans, paintings; the closer the pin, the more points.
• Pairs: countries and capitals, flags and names; each pair matched earns points.
• Slides: announce rounds and rules between questions.
