I already had a couple of Famicom game jigsaw puzzles featuring Star Force and Yie Ar Kung Fu which I picked up a few years ago and look like this:
Those ones were produced by Amada, a company which put out a lot of Famicom related odds and ends back in the 80s. The ones I got this week on the other hand were put out by a different company called Toyo. In addition to featuring different games and coming in differently designed boxes the big difference between the two is size. The Amada ones are small puzzles with only a dozen pieces, while the Toyo ones are bigger and contain 60 pieces each.
As the photo at the top of the post indicated the four I got were Balloon Fight, Donkey Kong Jr, Front Line and Exerion. These games were put out by three different makers (Nintendo, Taito and Jaleco) whose company logos are on the front. The Amada ones (at least the ones I have) featured games by Hudson Soft and Konami.
The back of each box has a checklist of the six different puzzles. In addition to the four I have they also made Wrecking Crew and Hyper Sports. I'll have to find those at some point so I can complete the set!
The back also tells us that these cost 100 Yen each back in 1985, which was a pretty good deal (I paid way more than that for them in 2020!)
The sides of the boxes say "Pocket Jigsaw Puzzle" in bold lettering:
