This is another great piece in the "dumb" set. It's not as easy as the rest, and possibly the toughest of the set, so it gives a proper feeling of satisfaction. However, it's still a part of the "dumb" set.
Anyway, this is actually quite an interesting puzzle and you can buy it very affordable as part of the "dumb" set.
Difficulty: 4/10
