From official web page (translated from Spanish): "Sabidurius is a board game based on the words, definitions, imagination and writing. Unlike other games where knowledge is crucial in Sabidurius age and cultural level doesn't care. Sabidurius rewards imagination, your ability to create definitions that sound convincing without worring whether they are true or not. And since anyone can make up a definition, anyone can play Sabidurius." The game-play is simple, all players must create definitions for words (a selected set of unusual words from the dictionary), then players vote for the definition that they think it's correct. If a player votes your invented definition, you get points. If you vote for the correct definition, you get points. So simple, so fun.
