The memory game, played by a whole room at once.

One board goes up on the big screen and the room is split into teams, up to four of them. When it is your team's turn, everyone on it votes for the two cards they think match, and the most popular choices are the ones that turn over.

Find a pair and it stays face up and scores. Miss and the cards flip back, and the next team goes.

Watching is part of playing

Every card another team turns over is information you get to keep. So nobody drifts off between turns, and the room is quietly building the same map of the board together.

That is the whole trick, and it is why a game this simple holds a big audience.

You decide what the pairs are

The fun part is a pair can be:

• a picture and a word
• a country and its capital
• a question and its answer
• a term and its definition
• a product and its logo
• the same word in two languages
• a sum and its answer

Upload your own images, generate word pairs, or mix types in one board. Set the board size for a quick warm-up or a long competitive round.

Who it's for

Trainers and teachers, because you can put your own material on the cards and it stops feeling like a test. Event hosts with a big room and a screen, because everyone can take part from a phone with nothing to install.

It is turn-based, and it is calm

Only one team acts at a time, so this is focused rather than frantic.
