Google is temporarily adding a version of the classic game Snakes into its Google Maps app for April Fools’ Day this year.

The company says that the game is rolling out now to iOS and Android users globally today, and that it’ll remain on the app for the rest of the week. It also launched a standalone site to play the game if you don’t have the app.

Users can find the game in the menu of the Maps app. To play, you select a city (Cairo, São Paulo, London, Sydney, San Francisco, Tokyo, or the entire world), and swipe to move your train or bus around the map to pick up passengers and landmarks.
