Post Path

Cross every lane once, then finish at the gold postbox. Revisit islands, never reuse a lane.
Lane crossings are not stops unless marked by a lettered island.
Tap an adjacent island or its destination button. Keys 1–8 choose island A–H.
← / → select a destination · Enter / Space cross · U undo · P pause · R restart · F fullscreen.
Getting stranded or finishing at the wrong island costs a tangle. Three tangles end the trip.
Retry map clears your route without a penalty. No time limit.
