this is a very simple puzzel to print but it has a trick in solving it that makes it harder than you think.

It was on the show “survival” were the contestants could not solve it after hours of trying. for some it is supper hard but for some supper easy. try it for your self!

the rules:

start like the picture (left side) and by only sliding the pieces on the base get the square piece into the frame (right side of the picture).

good luck! (think outside the box, the solution is easy, no lifting or any tricks only sliding) 

no supports, you can change color in the last two layers for even better looks.
