"This is the so-called 'Quaternary Box'. It takes 1536 moves to open. About ten years has passed since the creation of 'Ternary Box' (Super Cubi). It was designed for the International Puzzle Meeting of 2010. 'Binary Box' has a 'U'-shaped groove for the trick. The 'Ternary Box' has an 'S'-shaped groove. Therefore, since the creation of 'Ternary Box', the designer thought that the 'Quaternary Box' could have an 'M'-shaped groove somehow. But, in fact, the 'Quaternary Box' also needed a groove that is shaped like a 'comb', not only an 'M'-shaped groove. 'U'-shaped groove, 'S'-shaped groove and 'M'-shaped groove have no branches. So, I will call the grooves like them as 'snake'-shaped grooves. On the other hand, I call the groove that is just like 'comb', 'comb'-shaped groove. Thus, it is expected that an 'Even Number Notation Box' is made of 'snake'-shaped grooves and 'comb'-shaped grooves, and an 'Odd Number Notation Box' is made of only 'snake'-shaped grooves." -Karakuri Creation Group
