You can't jump over a marker, you can only move sideways or into and out of the centre space. You can't have more than one marker on a space. Your strategy will be to block your opponent's markers by surrounding them and by having one of your markers in the centre space. For the first move, each player can only choose one of the 'guard' markers. The first player chooses one marker to move to the centre of the star.
Players take turns in moving to an unoccupied space.
This can be the centre of the star or at a point of the star. To make the game more complex, the number of points on the star can be increased. Make sure that an even number is chosen. The two 'guard' markers for each player are always placed at the outside of the set of markers.
