Square Spin History: #1>#2>#3>#4

New Rule

This puzzle introduces a new square type:

  • Lonely squares (Ly)

Lonely squares

This type of square contains a box and it is the exact opposite of the Re square type. All moves where an Ly is replaced by a square of equal colour upon completion is prohibited. This square type is also ambiguous just like the Re!

For example this move is valid A T shape spinning However, the tricky logic of this square makes this seemingly intuitive move invalid... Miniature clock wind ...because it cannot even replace itself!

Recap of Previous Rules

  • Basic rules from #1
  • Ambiguity, Un and Re squares from #2

Problem #4: Rude Awakening

By the time you see this puzzle I'll be asleep. Making rules is exhausting! Please wake me up when you've found the answer to this puzzle... by finding the answer - to this puzzle. ZZZZZZZzzzzzzzz... enter image description here Get a 7x7 grid to work with here

Hint

The tables have turned!

  • $\begingroup$ Due to the nature of this puzzle I expect a slightly more detailed answer than just the solution. Also, I might soon take a break from these puzzles for a while and focus on other types of puzzles! $\endgroup$

  • $\begingroup$ If my bounty runs out I'll answer this, but I'd feel better if more people tried it. It's at least as good as the first puzzle was... also no idea if I'm at the optimal point yet. $\endgroup$

  • $\begingroup$ @Parseltongue Thanks! Actually, I programmed a basic tool which helps me build these puzzles and save them as images as well as perform rotations. The code underlying the logic of the game is surprisingly simple. I might consider publishing the tool (in some form) in the future so that the solving side is just as natural as the creation side! $\endgroup$

I did it in 8 moves, here's my solution. I didn't mark squares as lonely, since all white ones are lonely and I did it in paint. Also I didn't give a turn direction but it should be obvious.

  • $\begingroup$ Great work. Better than mine (I was at 10). Seeing yours it makes me feel like I over-complicated things for myself. $\endgroup$

10 Moves So as I disobyed the very first rule, this time i worked with 2x2 square blocks instead of 1x2 or 2x1 blocks as per specified rules by the OP. As for any other rule violations, i'm sorry if I did, but here is my solution:

Solution

OLD ANSWER 9 Moves

I tried this puzzle for the first time, so I hope I followed the previous rules OP has posted. I went for 1x2 and 2x1 rotations so I hope that such rotations are allowed. Also, if i understood correctly, you cannot replace a double square block by itself, but you can replace it using other double square blocks. So this solution, I went for 5x5 blocks not 7x7. My Solution: https://i.stack.imgur.com/ob41Q.png

Please tell if I disobeyed any rule, but hopefully not.

  • $\begingroup$ Yea, you've violated the 1st basic rule. You can only select an area of squares that is itself a square. Hopefully that is more clear, it looks like you've understood everything else though $\endgroup$

  • $\begingroup$ Your answer is now valid. However it can be done in less moves! $\endgroup$

  • $\begingroup$ @Adam Pelican did it in 8 moves, is it possible in less? $\endgroup$
