A gaming system and method are disclosed as having different symbol sets associated with different win rates that are combined to create variable win frequency gaming. The gaming system may include a plurality of reel strip sets. Each reel strip set may include a plurality of reel strips. Each reel strip set may have a different probability of achieving a predetermined outcome. After a predetermined outcome on the gaming system is generated, the gaming system may select a different reel strip set having a different probability of achieving a predetermined outcome. In some embodiments, the selected new reel strip set may have a higher probability of achieving a predetermined outcome than the current reel strip set. The higher probability of achieving a predetermined outcome increases the chance that the subsequently played game(s) will also result in achieving a predetermined outcome for the player.
