HOW TO PLAY Every puzzle has the same four rules: - Place exactly one lighthouse in each colored region. - Beams shine the full length of the row and column from each lighthouse. - No two lighthouses may share a row, share a column, or touch in adjacent spaces, including diagonally. - Every cell must be lit by at least one beam. If you get stuck, spend a hint to place the hardest remaining lighthouse. Hints come from optional in-app purchase packs, or you can watch a short rewarded ad for a free one.
