Let's say there are three 5 A hole , At the beginning, little fox took one of the holes , Then the player opens a hole randomly , If there's a fox in it, it's caught , If there is no fox in it, catch it the next day , But the next day the fox will jump into the hole next door before the player comes . If caught within the prescribed number of times, it is a success .
