For this year’s April Fools, Google has a Pac-Man option on GoogleMaps.
However, it cryptically references clues in which you can play the Pac-Man maps on, as apparently not all cities are supported.
There’s a list of clues it has on its FAQ page, but I don’t understand most of them.
Which cities can I play Pac-Man in?
For the Browser version, any area with enough intersecting streets will work.
For the Mobile App version I actually found a good reference at this Mashable article:
1. Times Square, NY
2. Arc de Triomphe, Paris
3. Batu Caves, Kuala Lumpur
4. Plaza de la República, Buenos Aires
5. Niagara Falls, Ontario
6. Aman Square, Ad Doqi
7. Fraumünster Church, Zurich
8. Googleplex, California
9. Hanover Square, London
10. Taj Mahal, Uttar Pradesh
11. Metropolitan Art Institute, Phoenix
12. Plaza Del Ejecutivo, Mexico City
13. Neues Rathaus, Munich
14. Victoria Square, Adelaide
