Abstract: In a gaming machine having a set of reels (8) with fruit symbols equi-spaced around their peripheral edges, two of the reels (8) may each be provided with a shield (10) which would normally conceal the respective symbols from the player's view through the machine window. After a play when the reels (8) have stopped rotating, the player can select to reveal the symbol concealed by either or both shields (10), by moving the respective shield (10) which is pivotally mounted on the respective reel. Identification markings on each shielded reel (8) are always visible to the player to reassure the player that when the reveal facility is used no further rotation of the respective reel (8) takes place. The revealed symbol is combined with the other visible symbols to determine whether or not there is a winning combination.
