LightHouse: Logic Puzzle

Light every island. One lighthouse per row, one per column, one per island — and never two touching.

Every sea chart is a grid of islands. Place exactly one lighthouse in each row, each column and each island, and never let two of them touch — not even at the corners. Some charts hide reefs, and a reef must be lit by a lighthouse within two cells of it. Four rules, and that is the whole game.

No countdown, no energy bar. A wrong lighthouse costs one of your three lights and leaves a mark; finish a chart clean and your streak grows. If you know Star Battle, sudoku or nonograms you already know how to start — and if you don't, the first ten levels teach you one rule at a time.

Ela! Alfa BetaΈλα! Άλφα Βήτα

Learn the Greek alphabet before your next holiday — one letter at a time, then the signs you will actually see.

Every Greek letter has three faces: the small letter, the capital, and how it sounds. The game lays one of them on the board and you find the other two. Tap a tile to place it. Three mistakes and the level starts over — no lives, no timers, nothing to wait for.

Levels begin with two letters and grow to seven. Each one ends with the letters read aloud and a short test that quietly brings back earlier letters, and every tenth level is a real Greek sign built only from letters you already know. From level 11 the words arrive: 600 Greek words and signs sorted by theme — the ferry, the taverna, the beach, the pharmacy.
