“The Real McKoi” in my opinion is hands down THE best Tormentor Stave has created! It is double sided and the coloring on both sides is gorgeous!! It’s so zen-like you forget how difficult (or don’t even care how difficult) it is getting everything together. The border is totally irregular so you have no guide to picking out edge pieces, unlike the fan shaped Tormentors or circular ones such as "See The Rain, Dear." "The Real McKoi" is difficult, no question about it! I wouldn’t recommend it to a novice. But if you’ve done other Tormentors with a high difficulty rating and enjoyed them, then you should definitely get this one! This is just an astoundingly fun puzzle to build.
