+
+## **Description 📃*
+<p>The farmer is the only one who can pilot the boat. The boat only carries two at a time. The goat can never be left alone with the cabbage, or it will devour it. The wolf also cannot be left alone with the goat, or it will eat it too. Can you cross them all?</p>
+
+## **How to play? 🕹️**
+<p>Click on the farmer, wolf, goat or cabbage to enter or leave the boat. Click the boat to cross the river - it'll only do it if the farmer is inside.
+<li>The boat can only carry the farmer and one other item at a time.</li>
+<li>The farmer cannot leave the wolf alone with the goat.</li>
+<li>The farmer cannot leave the goat alone with the cabbage.</li></p>
