I wanted to do all the weekly competition events blindfolded one week. For fewest moves, I used the following rules:
1. You can still use all the same materials as normal fewest moves: 3 cubes, pen, paper, stickers if you want.
2. You can hold a cube and use it as a prop to think about moves, but cannot apply the scramble. All you can do with your cubes is look at your solved cubes. LOL!
3. After your inspection is complete (which counts as part of your hour), you must apply the blindfold. Then the blindfold must not be removed until you're finished writing a solution on the paper.
4. As with normal blindfolded, you can turn the cube if you find it helpful while you're blindfolded. This actually had a bit of a benefit for me because I was doing effectively a blindfold solve, and sometimes my hands remembered the move better than my mind. When I needed to do that, I very carefully placed the pen in a position to point to where I needed to write the next moves, so I wouldn't mess up the solution.
5. When finished writing the solve, stop the timer and remove the blindfold. The blindfold may be removed before stopping the timer, but no additional moves can be written once the blindfold has been removed.
This was only doable for me because back when I did it, we didn't have the 80 move limit. So I worked out the positions of the pieces by tracking the moves in the scramble mentally, memorized a blindfolded solve, and then wrote down the moves to execute it, and it was well over 100 moves. Now, the only reasonable way to do this is to do a speedBLD solve, but with the added disadvantage that you cannot apply the scramble to look at while memorizing it - you have to execute the scramble in your head. Doing that in under an hour might be pretty hard, but is probably not impossible.
Interestingly, one of the most difficult things for me was keeping track of where my pen was as I wrote, so as to maintain a legible solution that was in the proper order. I really worked hard to keep track of where my pen was so that I wouldn't overwrite the lines somehow and invalidate the solve. And yet my solution was still awfully sloppy. But I can honestly say that the solution was still quite readable and clear as to its meaning and order, so I considered it a valid solve.
Easily one of the silliest events I've ever tried.
