IQ Lolly series is designed by Patrick Chan, a Hongkonger who claims that he is always inspired by young people.
This nice looking sliding puzzle has been designed, crafted and presented by Patrick for the IPP design competition 38 (2018) held in San Diego.
What about the look: this is a really nice looking puzzle and guess what? It's made with 3D printers and the quality is, in my mind, stunning. It's indeed very smooth.
The goal of this puzzle is to scrambled the numbers by pushing/pulling/turning the rod and then revert to the initial position.
3 levels of difficulty: the more numbers you have, the more difficult the puzzle is, of course!
The nice features of the puzzle: when you push and release then it's goes in the "middle" position. Same if you pull and release the rod. It's like the cutting corner technique of the famous rubix's cube: it's a way to be faster to solve the puzzle.
Also if you don't turn completely the rod of a turn, there is a little somthing that prevent from screwing up the puzzle (pushing/pulling if the numbers are not horizontally aligned). See below:
When playing with the Lolly you will notice that you cannot turn 2 times on the same way (I mean 2 times clockwise or counter-clockwise).
So far I am not super fast to push/turn/pull, but I think this is just a matter of practice :)
How to solve the puzzle you may ask? Well there are algorithms (see again a common point with the rubix's cube) to rearrange the numbers and several steps to be performed.
Easy if you follow the steps. Way more difficult if you try to discover them...
A nice video of Patrick's skills to solve: HERE
I am not that used to sliding puzzles, not even with 3D printed sliding puzzles and I must admit I like it a lot. Consider asking Patrick a copy of it. I suggest to go with the easiest level ;) Don't be a fool!!
The IQ Lolly comes in 7 different colors: you can see HERE the website (it's still under construction but gives you an idea of the colors.
Did I say that there are some Easter eggs to discover? Patrick mention that on the solution he sends. So far, I have not idea about what they are....
EDIT: I found the 2 Easter eggs. Nice!
