Google Maps has added their own little April Fools joke by letting you play some Pac-Man. There should be an option in the bottom left corner to play after you're on Google Maps' main page. The road maps will be what Pac-Man navigates through in the game.

Personally it can get a little wonky when trying to go through split roads but other than that it's a pretty fun distraction. You can try it out for yourself here.
