Superman brought a puzzle from the four-dimensional world. In the four-dimensional world, one object can pass through another, which is very convenient for creating puzzles. However, when you bring that puzzle into our three-dimensional world, the pieces get stuck together and won't move, which is inconvenient.
So, as before, Superman modified it with LED-equipped version and brought it back. The puzzle board, overview, and instructions for playing were as follows:
<Puzzle board (Initial state)>
<Overview>
1. A total of 36 LED squares are arranged on the board in a 6x6 grid.
2. Each square is a switch in itself.
3. Each LED square can emit one of 4 colors (blue, red, green, orange).
4. There are Scramble and Reset buttons at the bottom of the board.
<How to Play>
1. Press the Scramble button. The 4 colors will be scattered across the squares, and Solve will begin from this state.
Example of Scrambled state
2. Select 4 consecutive squares in a row vertically or horizontally and press them with your finger. The pressed squares will start flashing. If pressed correctly, the color of each LED will change as if the rectangle formed by the 4 pressed squares has rotated 180 degrees, and the flashing will stop. If pressed incorrectly, the LED colors will not change and the flashing of the squares will stop.
3. Repeat the action in step 2 above until you reach the <Puzzle Board (Initial State)> shown in the diagram above, and the puzzle is solved.
4. If you want to stop midway, press the Reset button, and you will return to the solved state as the <Puzzle Board (Initial State)> .
For example, the "Example of Scrambled state" in <How to Play> 1 above can be solved in 4 moves using the following procedure:
The 4 squares (selected squares) surrounded by the white rectangle will change to the color surrounded by the black one.
It seems impossible that a puzzle with such a simple concept hasn't been invented yet, but according to Superman's research, there isn't one yet.
Finally, I've added 10 more moves to the "Example of Scrambled state" from <How to Play> 1 above to create the Scramble shown below.
Can you solve it, readers?
