Rules — three of them

1. Every square is filled (orange) or empty (white). Click to cycle.
2. Never three of the same in a row, across or down.
3. Every row and column holds three of each.

That's it

Squares with an inset outline were given to you and can't change. There is exactly one solution and you never need to guess — every move can be reasoned.

A new grid appears at midnight. Same one for everyone.
