Yvo is a board game for two to nine players, that lets you practice with grammar in a playful manner. Yvo is similar to Scrabble or Wordfeud, but instead of composing words with letters, players compose sentences with words. The iPad is the gameboard on which the players put the words from their shelf into a gramatically correct sentence. The players determine mutually whether a sentence is grammatically correct. When putting a word, a player can change its form such as the conjugation or tense. Further, Yvo can speak out loud words and sentences, and players can look up its definition. Yvo is available for free in the App Store.
