I don’t know how long this will be around because it is an April Fools thing, but you can play the old Snake game in Google Maps – I played it on my Android phone.
Open the menu at the side and there is a new menu item half way down: Play Snake. Tap it and follow the instructions to play the game.
You get old-style blocky graphics and you swipe up, down, left, right to change direction. It’s not a snake though, it is a bus and you pick up passengers on the map. It’s a bit of fun for a few minutes.
