"The river crossing puzzle is a challenging logic game. You need to guide the boys and devils across the river, but you must be careful not to let the devils outnumber the boys on either side of the river. If the devils outnumber the boys, they will kill the boys. To move the boys or devils, click on them. To move the boat, click the GO button. The boat will move in the opposite direction of the click. Be careful not to let the boys or devils fall off the boat!"
