Rules

The person playing the geese starts by moving one of their figures left, right, or straight to a vacant field.

The fox can move the same way, but has the ability to catch a goose by jumping over it (straight, not diagonally), if the field behind it is vacant.

The geese win when they manage to circle the fox so it can't move anymore.

The fox wins when there aren't enough chicken left to circle it.

Variations

The game can be played with 20 geese instead of 13 where diagonal moves are also legal.
