You want to install a fast acting fuse. Slow blow fuses (or time delay) are primarily to protect motor loads where the initial starting current will exceed the fuse rating by many times.

The fuse in your game is there to protect the wiring. You do not want a delay.

If you are thinking that the playing the game in “multi-ball” mode is overloading it somehow, I would reconsider. It is more likely that the little gremlin is somewhere in the game, not the one playing it.

Most EM games draw between 3 to 4A during even a busy game. Your 5A fuse operates on an inverse time characteristic curve meaning it will actually carry more than 5A for a specified length of time. If the fuse in your game is blowing, there is something wrong.
