Surf is a browser game developed by Microsoft that is shipped with the Microsoft Edge web browser. In the game, the player must control a surfer as they move across a body of water while also collecting power-ups and evading obstacles and a kraken. The game features three game modes (classic, time trial, and slalom), has character customization, and supports keyboard, mouse, touch and gamepad controls.
Like Google Chrome's Dinosaur Game, Surf is accessible from the browser's offline error page and can also be accessed by entering
edge://surf into the Edge address bar. Its gameplay has been frequently compared to the 1991 video game SkiFree. Microsoft also hosts a version of the game with limited features that is playable from any modern web browser. The game is also included with the Android and iOS versions of Edge.
In 2021, the game was updated with seasonal theming that changed the surfer to a skier on a snowy mountain as an homage to SkiFree. The kraken normally in the game was also replaced by the Abominable Snowman, also from SkiFree.
