A gaming apparatus comprises a movable symbol selector and a reference object. The symbol selector has a plurality of presentation portions. Each portion is associated with one or more symbols of a first set of symbols. The reference object comprises a plurality of parts over which the selector can be moved. Each part is associated with one or more symbols of a second set of symbols. When the symbol selector moves relative to the reference object at least one relationship is formed between at least one of the selector portions and at least one of the reference object parts. The at least one relationship is for use in determining a game outcome.
