SISU

Product Info

Kevin Sadler reveiws SISU:
“The word Sisu is a Finnish word – it is not easily translatable into English but it roughly means: Strength of will, determination, perseverance, and acting rationally in the face of adversity. Does this mean that it requires enormous strength of will to solve it? I also noticed that there is a hole in the box which goes all the way through.  It has been beautifully made by Jakub and team from Mahogany, Ash, some magnets and a steel ball bearing. It is a restricted entry packing puzzle as we have seen many times before and also has pieces that are based on the Soma puzzle. Making this one very different from the others we have seen before, the pieces have some beautifully drilled holes in them. Some of these holes are blind ending and others are part of a channel through the piece and out another hole. The aim seems to be to assemble the pieces in the box and close the lid on top and then to roll the ball bearing through the maze that has been created until it comes out the other side. This means that the assembly requires the formation of a maze that goes entirely through the puzzle. This significantly adds to the challenge! Now this is an interesting puzzle to write about!  I went to BT and discovered that there is only one possible assembly for these pieces into a cube. I will then need to see how to get them into the box through the H-shaped entry – I assume that only one of the 6 possible orientations of the cube will be possible to assemble in the box and probably not without some fancy sequential moves. The pieces that have rotational symmetry will need to be oriented correctly to form the complete maze – whilst the piece shape might be symmetrical, the holes and channels are not. After this I will have a blind maze to negotiate with the ball bearing. I love a puzzle with multiple challenges and this will require some significant “Sisu” to achieve it! Despite not having completed the challenge yet, I know that this will be an essential purchase for you all.”
