FAQ
What are the rules of wolf, sheep and cabbage?
The farmer can cross the river with only one thing in the boat. On a bank without the farmer, the wolf eats the sheep if they're together, and the sheep eats the cabbage if they're together. Get everything across to win. The fewest is 7 crossings. (It's also known as the wolf, goat and cabbage puzzle.)
What are the rules of missionaries and cannibals?
There are 3 missionaries and 3 cannibals. The boat holds 1 or 2 people (someone has to row, so it can't cross empty). On either bank, if there are missionaries and the cannibals outnumber them, the missionaries get eaten. Get everyone across to win. The fewest is 11 crossings.
How do I play?
Tap who's on your bank to put them in the boat (you can also take nobody), then press Cross. Combinations that won't fit or moves that aren't safe can't be made.
How is the leaderboard ranked?
By moves (number of crossings), fewest first; ties go to the shorter time. You only need a nickname, and you can submit up to 30 times a day. The server verifies your moves.
