Wordfib is a vocabulary game built around one question: which meaning is real? Every word comes with its true definition and three convincing fibs. Pick the real one, hear the word said out loud, and see it used in a sentence, with a short note on where it comes from.
There are five levels, from Bookworm for young readers (ages 7 to 9) to Lexicographer for lifelong word lovers, with 7,500 words in all. Get enough right and you move up to the next level.
It's free, and it's made for families: each player on a device has their own level and progress, a grown-up sets up each child's player, and there are new daily games every day.
