Sektorlos

A deductive night-navigation puzzle: find the way through a dark archipelago by the lighthouse sectors

Et deduksjonsspill for deg som liker tankenøtter: finn leia i mørket etter fyrlysets sektorer.

Play Sektorlos

A puzzle for one player in Norwegian (bokmål): steer a pilot cutter through an unlit archipelago to harbour by reading the lighthouse sectors, in a round of 10–20 minutes, on phone or desktop. Where a light shows white the water is clear of rocks, red and green warn of foul ground, and two white sightings of the same light prove the whole arc between them safe. Every map can be solved by deduction alone, and «Nytt kart» makes a new one. Play with the arrow keys, the on-screen compass or by tapping the chart.
