On one bank of a river, there are three lions and three bulls.
There is one boat available that can hold up to two animals at a time.
The danger: If the lions ever outnumber the bulls on either bank, the bulls will get eaten.
Goal: Get all six animals safely across the river.
Use the interactive to find a safe sequence of trips!
