Over the Edge is a surreal role-playing game of secrets and conspiracies, taking place on the mysterious Island of Al Amarja. It was created by Jonathan Tweet with Robin Laws, and published by Atlas Games. Over The Edge departed from the model of predefined character attributes and skills, in favour of player-chosen traits; and was among the first to be based on the dice pool, where the number of dice rolled, rather than how they are interpreted, is determined by the characters' abilities.

Jonathan Tweet is an American game designer who has been involved in the development of the role-playing games Ars Magica, Everway, Over the Edge, Talislanta, the third edition of Dungeons & Dragons and 13th Age, and the collectible miniatures game Dreamblade. In 2015 Tweet released Grandmother Fish, a full-color, full-sized book about evolution aimed at preschoolers. In 2018 Tweet released Clades and Clades Prehistoric, two card games for children and adults which demonstrate the concept of a clade.
