What do you think of this idea for a 2d Rubik's Cube like puzzle?


Consider a 9x9 array of ones and zeros.

To make a move, you would rotate a column or row.

To rotate a column/row, you would shift the numbers over one position and wrap around a number from one end to the other while flipping its value from zero to one and vice versa.

The goal is to end up with the same number in all 9x9 locations.

It's not very intuitive to imagine how the numbers change. It could be fun to learn though. One way to know if it's fun is to make a simple version and play around.

For a digital puzzle, I think it’s is too easy, but may not have thought it through correctly (tip: don’t use zeroes and ones, but an image. That makes the puzzle more attractive and harder, maybe too hard)

For a physical puzzle, it would be a fun object, but I don’t see how to build it.

(Topologically, it’s a torus with a 9 × 9 grid, where each 9-item ‘row’ and ‘column’ is a Möbius strip with a zero on one side of each item and a one on the other (I would use two colors to make it more attractive))
