Wooden Bar Game, Made in Japan

Ok... I know little to nothing about this one but it looks like many different stacking notch puzzles out there. The instructions are on the bottom of the box... it really sets of a very vintage vibe... with late 70s/ early 80s style fonts. It says it is a bar game and then immediately calls itself an executive brain teaser... and later great for cocktail parties... ummm. Ohhh kayyyy... maybe it should also be fun for all ages and be used in a Lite Brite as well?  ANYWAY... I kid... I think the kitchen factor maks it cool all the same and a definite conversion piece as well as a fun puzzle.
