But 324 steps Super Cubi is certainly difficult to open. 

   

  

 

    People normally start thinking about something other than puzzle when they are not concentrating on one thing. The mind drifts away start thinking about the smell, temperature, what you are going to eat for dinner etc. It is rather hard to concentrate on one thig. 

    324 steps is certainly a lot of move and it takes a while to open and while you are trying to open the box, you mind gradually drifts away from the box and starts thinking something else... 

    To solve the box, you really have to concentrate on the box and you have to keep track of where you are. Otherwise you can easily get lost in the middle and once you loose the track of where you are, then it is harder to figure it out what is the next move is. 

   While you are concentrating on something, you may forget any stressful event you suffered on that day and forget it. It is like when I am cooking at the kitchen, the experience of concentrating on cooking is sometimes very relaxing because I often forget other trivial things. 

    I like to sit on a comfortable sofa with my favorite whiskey and then do this Super Cubi as I sip it at night. 

    It is more than just a puzzle, but more like stress relief toy, I would say. 

    Moreover it is a perfect interior decoration, which you can enjoy just by staring it.
