Chances are that you’ve heard about the ancient river crossing riddles, but do you know them all? You may have heard about the farmer who must take a wolf, a goat, and some cabbage across a river, or a version featuring a fox, a goose, and a bag of beans. Maybe you know the problem of the three missionaries and three cannibals, or the “jealous husbands” variation.
Those are the classic river crossing puzzles. They are popular and well known, and they are all included in this game, along with many more.

River crossing problems date back to at least the ninth century, with the earliest known examples occurring in the Latin manuscript Propositiones ad Acuendos Juvenes (“Problems to Sharpen the Young”).

River crossing puzzles and their many variants represent ways of dressing up relatively straightforward mathematical problems. They invite attempts at a solution that range from trial and error to extensive mathematical analysis.

These puzzles are frequently used in job interviews. They are also taught to children in schools to boost their IQs and improve their critical thinking, mathematical problem-solving, and strategy development.

Your goal in every level is to move all of the characters across the river while observing certain rules and restrictions. Once you have completed a level, you will receive one star for level completion. You can obtain an additional star if you finish the level in the minimum number of moves, and another if you finish the level in a set time that varies from level to level.

Try your best, work as quickly as you can, and keep your number of moves low to earn more stars. Your total number of stars will help you access more advanced levels.
