Eat them in a chain
The first ghost you catch after a power pellet is worth 200. The second is 400, then 800, then 1600, and the window is short enough that getting all four takes planning rather than luck. Herd them first, then eat the pellet. Everyone does it the other way round for about six games.
Fruit
Something appears in the middle of the maze twice per board and sits there for a few seconds. It is free points and it is always in the least convenient place, which is presumably the idea.
The tunnels are the whole game
Two of them, level with the ghost house. A chase that looks finished stops being finished the moment you commit to one, because the ghosts have to go the long way round and you come out the far side with a clear run.
The doodle that stayed
It went up in 2010 for the game’s thirtieth birthday and was supposed to last two days. It was written properly rather than faked with images, kept the original ghost logic, and hid a second player behind the coin button. The reaction was big enough that it was given a permanent home instead of quietly disappearing.
Most do not get that treatment. Google zipper lasted one day. Google block breaker lasted years and still went.
