LightHouse: Logic Puzzle

Find the perfect spot. Light every island.

LightHouse is a relaxing logic puzzle game inspired by Star Battle. Place one lighthouse in each row, column and coloured island — without letting any two touch, even diagonally. Simple rules. Clever puzzles. That satisfying moment when everything clicks.

Love sudoku, nonograms or queens puzzles? Discover a colourful new way to put your deduction skills to work. Play offline, take your time and solve each sea chart one lighthouse at a time.

A SMALL SET OF RULES. A WORLD OF PUZZLES.
• Place exactly one lighthouse in every row.
• Place exactly one lighthouse in every column.
• Place exactly one lighthouse on every coloured island.
• Keep lighthouses apart — including at the corners.

Mark impossible spaces with an X, narrow down the possibilities and uncover the solution through logic. An interactive tutorial helps you learn by playing.

As you progress, reefs add another layer of deduction: light each reef with a lighthouse one or two cells away in the same row or column.

THREE LIGHTS. A FRESH CHALLENGE.
An incorrect lighthouse costs one of your three lights and leaves a mark on the board. Run out of lights and you can continue once or start the puzzle again. Aim for a mistake-free finish and grow your streak.
