The game is activated by heading to Google Maps and clicking the little icon in the bottom left hand corner, next to the sign that usually allows users to switch between the map view and the satellite image one. Clicking the little Pacman image brings up the Pacman view, overlaying the game on the streets of wherever you were looking.
Some areas — such as around the Taj Mahal — seem to have been chosen as perfect places to play the game, and as such have a huge Pacman marker placed in them. In those places, explorers can click on the button and have the Pacman game launch."
