Abstract
A slot machine issues awards for winning combinations formed by an initial spin of all symbol positions in the symbol matrix and subsequent re-spins of all “unlocked” symbol positions until all symbol positions have been “locked.” In a preferred embodiment, an initial spin uses all slot reels and pays for all winning combinations displayed; a pre-determined symbol “locks” all of the symbol positions on that slot reel; “unlocked” reels re-spin and re-pay until all slot reels are “locked.” Other embodiments of the present invention are described within the application.
