A few sellers are selling fake Game&Watch items on eBay. Be careful when buying G&W! 
Collectors of Game&Watch might think they have seen all games of the Game&Watch series including their variations (editions, packaging). But still, there are surprises! A short while ago, even two very rare games were sold on eBay!
One of them was a Fire FR-27 from the UK, which has a logo imprinted on the left side. There are a few such advertising games known (see this article), but such a Fire is the first one ever seen. It's not known which company uses this logo or did use it. If you know anything about it, please contact me, thank you.
The other game was a Climber DR-106. We know this game was sold in a box, but this one came inside of a blisterpack. It's unknown how many of them were produced. This one is the first one I've seen.
As you see, Game&Watch still has many surprises, that's one of the reasons what makes collecting Game&Watch so exciting. How long will it take until we see an unknown item again...?
