River Crossing Redux
A mobile-first, fully self-contained puzzle app: twelve river-crossing logic puzzles from fox-goose-grain to jealous husbands, missionaries and cannibals, bridge-and-torch and capacity-three variants. Drag passengers into the boat and drag the boat across; illegal states are explained, moves are counted against the known optimal, a history strip records visited states, and a shareable result card celebrates your solve.
