So, you know, I was all like:

This is one of those little bits of gaming history I have been looking to snag for the longest time. As every retro game collector with a penchant for useless trivia (ie every retro game collector) knows, Puck Man was the original name given to Pac Man.
When they discovered the ease with which the `P` in Puck could be turned into an `F` by 1980s kids with their devilish (dare I say?) senses of humor, they hastily changed the name to Pac Man.
So I don`t think it was ever known as Puck Man in North America, but for a short time that was the name of the game in Japan.
It is very hard to find physical remnants of this little quirk in the history of Pac Man, in fact my new Tomy handheld is the first time I have seen anything with Puck Man on it. By the time the game was released on the Famicom here it had already adopted the new name so I don`t think there are any other home game releases with the Puck Man title.
For an early 1980s handheld it is a pretty good game. You have two settings, amateur and pro. I`ve only tried amateur. Basically it is Pac Man only the screen isn`t the same as in the arcade or console versions and you don`t have the same range of movements. The sound effects are awesome though, it plays the Pac Man tune when you turn it on. Music to my ears. Literally.
I love everything about this actually. The design is perfect. It actually looks a bit like Pac Man...er I mean Puck Man. It also looks somewhat like a microwaveable container with buttons. But, you know, in a good way.
A very nice addition to my growing handheld collection:)
