"Tetracube is an ingenious design. Congratulations, Maxim. You have solved a problem I'd always wanted to solve!"-Henry Harrius Tetracube is an instant self solving cube - in the air - that anyone can solve without knowing any algorithms! It does not require any practice It is self working. Instant reset. Durable gimmick. And revolutionary mechanism! As seen on TV shows. Instead of thinking of Tetracube as a singular effect, it’s best to think of it as a versatile accessory. You’ll have as much fun coming up with ways to use it as you do performing. It’s a guaranteed showstopper. While it looks impossible Tetracube is incredibly EASY to learn! Just toss the cube in the air and it’s solved. Or, since you receive a blank cube and stickers, you can even customize it for coincidence or matching cube effects. "Maxim is a creative genius and has transformed Rubik's Cube Magic." -Steven Brundage
