Object: Relign the 9x9 grid's 3x3 sections, to match regular* solution rules.
Click upon the visible (blank) 9x9 grid to initiate a new puzzle. Once done, the computer will then rotate various 3x3 sections; all of the numbers are thus pre-given to the solving player.

Click upon any of the top-left cells of the 3x3 sections to rotate their section's numbers.
Unlike my other puzzle, Rotation Squares or the LightsOff puzzles for example, adjoining sections are not affected by rotation moves.
Variants differ by taking either one or two squares' sliding moves. There are also variants where the bottom right 3x3 section [brv] will not be pre-rotated. In all variants, whether any available 3x3 section is rotated - any number of times, either clockwise or counter clockwise, and/or subject to follow-up reversing rotation(s) - is made by a random selection.

Two valid solutions are available, the expected right-side up pattern, and also a flipped over 180 degrees pattern of all 3x3 sections.

Downside note:
Not every initiation process may generate a valid puzzle. I could only test this via a 15 year-old laptop running Windows 2000 (lol). I expect that result should be easily improved upon with more advanced computing hardware.
