Lighthouse Keeper

Take the night watch in Lighthouse Keeper, a cozy timing and optics puzzle set on a dangerous coast. Rotate a Fresnel-inspired lighthouse beam, choose red, green or white navigation sectors, open the shutter at the right moment and use the foghorn when visibility disappears. Fishing boats, ferries, cargo ships and sailboats approach with different speeds and turning behavior. Read each vessel's cue, line up the beam and guide it through reef channels before it reaches the warning zone. Fog, rain and storms make later watches more demanding, while the horizon gradually moves from deep night toward dawn. Complete 35 handcrafted missions, earn medals and Brass Tokens, unlock new watches and restore the keeper's Lens Room, Chart Desk and Radio Set. When the campaign is complete, or whenever you want a longer challenge, Endless Watch continues generating new traffic as the pressure rises. Lighthouse Keeper works fully offline. It has no ads, no accounts, no subscriptions, no in-app purchases, no analytics and no network requirement. Progress and settings stay on your device.
