Seed: 000000213 I don't believe the following path should solve the puzzle: Screenshot_2024-06-20-02-10-44-64_b9da37f254079e85909e85e628f7a824 Once the pink square is taken care of by the first eraser, the second eraser has nothing left to fix. I don't believe erasing a green square is valid. So that shouldn't work.

A correct solution for this puzzle would be: Screenshot_2024-06-20-02-15-01-45_b9da37f254079e85909e85e628f7a824 In this case the second eraser takes care of the two triangles which needs fixing.

Yes, i believe you're correct. Eraser must erase an unfulfilled rule and can not erase a satisfied one. More than two rules of one colour may exist in the same sector, unless one of them is a sun shape, but they're not. Green square shouldn't be erased.
