Do the cards match the caller?

Yes. The cards and the caller use the same word list. Each card holds 24 of those words, a different set on every card, so a word called on the TV is on some cards and not on others.

Can I use my own words?

Yes. Type or paste one word or short phrase per line, at least 24. The cards and the caller both use that list.

How do I check a winner?

Compare the card with the board of called words under the big word. The page does not check cards: it prints them and calls the words, and the room checks its own cards.

Print the cards, then call the game on a TV

Print a set of cards and hand them out, then open the same words fullscreen on a TV, projector or laptop. Click, tap or press Space to call each word: it lands big, and the board below lists every word called so far, so players can check their cards.

Every card holds 24 of the words plus a free centre, and no two cards are the same. Change the list to your class, family or office party and print a fresh set; the cards and the caller always use the same list. Printing is done by your browser, so nothing is stored and no account is needed.
