enigmatic puzzle - (7 of 11: Fillomino) What is Pyramid Cult's Favorite Shape?


Dear PSE users and moderators,
I’m new here in PSE, but I really need your help. There was this person who gave me a black envelope consisting 10+1 pages of puzzles, and also a scribble saying: “Find our favorites and you will be accepted to join our ‘pyramid cult’. Feel free to ask for help from your beloved friends on PSE. They will surely guide you into all the truth.” I’m also a newbie on grid puzzles, so, could you please give me any hint to solve these? It’s getting harder and harder later on..

Answer



The answer is



SPHERE, obtained by taking the letters in the regions labelled 1




I was doing a step by step solution, then had to go, then there was Sconibulus' answer when I came back - anyway, I'll drop it there.



Easy first steps enter image description here
Then the first tricky part: if you assume that the two 8s on the right are not connected, you have an impossible situation in the top left (red question mark). enter image description here
Therefore: enter image description here Now the 7 cannot block the 6 underneath, which implies enter image description here The 6s on the left cannot be connected: enter image description here Again the 6s on the left cannot be connected, and neither can the 3s nearby: enter image description here The 6s must be separated by a 1, which clears the 6 on the left. The 4s cannot be connected, and therefore the 5s must be connected. enter image description here The central left 8 can't be connected with the topmost 8, which yields two more 1s and the rest is clear. enter image description here
