How to play
What is Sym-a-Pix?
Sym-a-Pix is a symmetry logic puzzle invented by Conceptis. Each cell shows a number 0–9 telling you how many of its 8 neighbors are filled. Fill in cells so every clue is satisfied AND the final grid is point-symmetric (180° rotational symmetry around the center).
How do you play Sym-a-Pix?
Click a cell to toggle it between filled (black) and empty (white). Right-click or long-press toggles the opposite. A clue 0 means all 8 neighbors must be empty; a clue 9 means all 8 must be filled. Cross-reference between adjacent clues to deduce the rest. The puzzle is solved when every clue matches AND the grid is point-symmetric.
