Logic Masters Deutschland e.V.

Standard Akari rules apply:
• Place lights in some unshaded cells so that every unshaded cell is illuminated.
• Lights illuminate the cell they’re in as well as all cells seen in a straight line horizontally or vertically up to either the first shaded cell or the edge of the grid.
• Lights may not illuminate each other.
• A number in a shaded cell counts the lights orthogonally adjacent to that cell.

Akari (RGB) rules apply:
• Each light has a color, R, G or B.
• A clue in an unshaded cell gives the color resulting from all lights illuminating that cell.
• M is R+B, C is G+B, and Y is R+G.
• Lights may exist on clued cells.
