Pseudo Ovolo - interlocking burr puzzle

The first time Juno saw Yavuz Demirhan's Ovolo, he really liked the concept of the puzzle. The assembled shape of the puzzle was also attractive and he thought that a similar puzzle could be designed.

He didn't want to copy the shape of the puzzle and made a slight modification to the assembled shape. Now, what is the difference in the shape of the two puzzles? Both puzzles, Ovolo and Pseudo Ovolo consist of six sticks. Comparing the orientation of those six sticks in the assembled shape, the difference is obvious. Two sets of three sticks are used for Ovolo and those two pieces don't touch each other. Three sets of two sticks are used for Pseudo Ovolo and the three pieces touch each other and make a loop shape.

He designed level 13 (it requires 13 moves to take the first piece apart) Pseudo Ovolo in 2015, and then he made some modification to the pieces to give structual strength in 2017, not changing the level of the puzzle. Small blocks were added to the conjunctional spots of the stick pieces to increase the gluing area.

Pseudo Ovolo is a very difficult puzzle because of its unusual transformation of the shape when it is assembled or disassembled. There are also lots of false movements to be disassembled.

The puzzle is sold assembled. The printed solution of the puzzle is enclosed.
