Lantern light on the water: the camp's islets are linked by rope bridges, and the night watch must walk every bridge before dawn. Crossing each bridge exactly once is the dream; some maps force a re-crossing or two. Three maps, exact fewest crossings shown after each round, no timer.
Each round shows islets (letters) and the bridges between them. Command walk A B C ... submits a full route as island letters; consecutive letters must share a bridge, and the route must cross every bridge at least once. Round score: 100 points, minus 10 for every crossing beyond the exact fewest (never below 0). Three maps of 6, 7 and 8 islets, max 300. Commands: walk ..., show, reset, help.
