Defining Square Spin
Lets play a game!
The aim of this game is to transform one image into another using the least amount of moves possible. Here is what a move consists of:
- You get to pick a square of any size in the grid.
- You then get to rotate the square around its midpoint as much as you want as long as it fits back into the grid.
- This is where your move terminates and the resulting image can no longer be modified unless you take another turn.
Problem #1: Sun and Moon
I'm a little tired after defining the game and it's too bright outside for me to have a nap, can you make it nighttime for me?
Get a 7x7 grid to work with here
What is the main difference between the sun and moon? Is it possible to 'fix' this in a few moves?
Your approach to hint 1 should leave you with a straightforward path to the answer. It will be clear that the answer is only a few moves away and the pieces should fall into place!
