The aim is to move all your blue marbles from your blue base across to the opposite green base.
You can move a marble to the space right next to it.
You can jump over another marble in a straight line - even skipping empty spaces.
After jumping over a marble, you can jump again in the same turn.
You cannot end a move in a base that is not yours or the green goal base, but you can jump in there and jump back out during a turn.
