It's a combination of the colorful designs and simple but fun game play that I like a lot. The packaging and overall game design also oozes 1970s style, which is the time period in which I grew up, so nostalgia probably is part of the appeal.
From a collector's point of view, it is also great that there so many different games to collect in this series.

For many years, I believed that the series consisted of 48 different games in total. Until a few months ago, when a 49th game was discovered.
Just recently, I discovered yet another Mini Game. It is called Block Puzzle (ブロックパズル) and dates from around 1972.
Although the two versions shown here appear to be different games, they are actually completely identical. The only difference is the sides of the blocks that are exposed on the front.
