Although this puzzle doesn't look as simple, it's the "all bark, no bite" type. The optical illusion might fool you and make you think that it's complicated, but it's just another piece from the "dumb" set.
Although it isn't the easiest one in the set, it won't have you frustrated over the problem-solving process too much.
Difficulty: 2/10
