Oleo 10 is the newest puzzle from Yuu Asaka! The goal of this puzzle is to fit all all 6 red circles along with 4 black rectangle pieces into the tray provided. Sound easy? There doesn't seem to be enough round holes to fit all the little red dots - the solution may require you to think unconventionally... As with other of Yuu's puzzles, this quality plexi packing looks better than the picture can depict.
The Puzzle Wanderer had this to say about the Oleo 10:
“I really recommend it for Wanderers (beginners)... It has a unique solution and it can be quite a challenge for the unexperienced puzzler. I don’t doubt Oleo 10 is a great entry point for Asaka’s popular puzzle series.”
The tray measures: 13.7 cm x 11.6 cm x 0.6 cm / 5.4 in x 4.6 in x 0.25 in
