Three Siblings And Their Dog River Crossing Puzzle | MindYourLogic River Crossing Puzzle

In this intriguing puzzle, three siblings need to cross a river with their dog. The boat is small and can only carry one sibling at a time. However, two siblings together can manage the boat, and the dog cannot be left alone with any sibling unless all three are on the same side. The challenge is to figure out how to get everyone across the river safely, following these constraints.

Steps:

1. Two Siblings Cross Together: Two siblings (S1 and S2) start by crossing the river together, leaving the third sibling (S3) and the dog on the original side.
2. One Sibling Returns: One of the siblings (S1) returns to the original side alone.
3. The Third Sibling Crosses: The third sibling (S3) then crosses the river alone, joining the second sibling (S2) on the other side.
4. Sibling 2 Returns: The second sibling (S2) returns to the original side alone, where S1 and the dog are waiting.
5. Both Siblings Cross Again: Now, S1 and S2 cross the river together again, leaving the dog alone on the original side.
6. Sibling 1 Returns: One of the siblings (S1) returns alone to fetch the dog.
7. Sibling and Dog Cross Together: Finally, S1 crosses the river with the dog, joining the other two siblings on the opposite side.

Conclusion:
By following this sequence of steps, all three siblings and their dog can safely cross the river without breaking the rules. This puzzle requires careful coordination and strategic movement to ensure that the dog is never left alone with any sibling unless all three siblings are together.
