Amid all the lame April Fools' jokes, Google has added a cool easter egg to Maps.

You can now play the classic game Snakein the Google Maps app, just by hitting the top left menu button in the app, and selecting the option to play. If the option doesn't show up for you, try closing and reopening the Maps app.

Once you're inside the easter egg, you can select between different cities you'd like to play on, including Cairo, London, San Francisco, São Paulo, Sydney, and Tokyo.

A neat touch is that each city features a snake which is coloured like the trains from that particular location (except San Francisco, which is a tram), and objectives which are shaped like famous tourist destinations.

The easter egg is available on the iOS and Android apps, but if you can't access it, you can open it in your browser here.

Google said in a blog post that the game will be available for a week in the app, but the browser version will be available much longer after April Fools' is done.
