Today's puzzle is a Nuri-Uzu! If you're finding yourself stuck, stick around to the end for another appearance of GAPP 101! (not factorial)

Rules: Shade some cells such that each group of orthogonally connected unshaded cells contains exactly one circle and has 180° rotational symmetry around it. No 2x2 area may be entirely shaded or unshaded.

As always, an example puzzle and its solution are attached to the image of today's puzzle. The example puzzle relies on the GAPP 101 logic too, so check that out if you're feeling particularly stuck! Solve the example here, if you wish (puzz.link): https://tinyurl.com/4b952ntt

GAPP 101: As a direct consequence of the rules, every 2x2 of cells needs to have at least one shaded and at least one unshaded. Sometimes there might be some 2x2s that are particularly difficult to reach with unshaded cells...

Hey hi hello hey... this is extremely embarrassing... but I messed up! The puzzle the link directed to was actually not the right puzzle, so I've fixed that now... I'm so sorry!!
