From the Discovery Bay website:
"In Literati Challenge, tall tales, side splitting yarns and hilarious verse are all part of the fun, but what’s best of all is you’ll be writing it! That’s right Literati Challenge is the new, laugh out loud party game of bluffing and creative chutzpa. Players get five words on cards. Each player must write a story using all the words in 90 seconds. The challenge? You may not know the meaning of the words, but to score points you need to make the other players believe you do. Players are scored during each turn. First player to reach 300 points wins. Literati Challenge is sure to get your creative mojo rising and your family and friends howling!"
This differs from Baffle Gab in that it is targeted for adults (Age 15+) where Baffle Gab is a Family game (Age 7+). The words used would be different and lend to a different experience. The most significant difference between these games is that in Literati Challenge, the cards provide word definitions on the back of the cards, while the cards in Baffle Gab do not.
