In one embodiment, the gaming system includes a curved display system for displaying a game. The curved display system has a curved material having an outer surface, an inner surface, and a radius of curvature similar to a mechanical reel. The curved display system also includes a digital light projection device for projecting images of one or more reels onto the curved material. The gaming system also includes a touch screen system positioned in front of the curved material. The touch screen system has a touch sensor assembly having a substantially transparent touch panel that produces touch data when activated, a touch panel controller for controlling and interpreting the touch data, and touch panel software for controlling and interpreting touch data. ## Claims ### Claim 1 A gaming system using touch panels as user control devices, the system comprising: a curved display system for displaying a game, the curved display system comprising a curved material having an outer surface, an inner surface, and a radius of curvature similar to a mechanical reel, and a digital light projection device for projecting images of one or more reels onto the curved material; and a touch screen system positioned in front of the curved material, the touch screen system comprising a touch sensor assembly having a touch panel that produces touch data when activated, the touch panel having an opening, a touch panel controller for controlling and interpreting the touch data, and touch panel software for controlling and interpreting touch data, wherein the touch screen system is configured at least for selecting one or more pay lines for the game, and wherein the curved material extends through the opening in the touch panel. ### Claim 2 (depends on 1) The gaming system of claim 1, wherein the digital light projection device directly projects images into the curved material. ### Claim 3 (depends on 1) The gaming system of claim 1, wherein the digital light projection device indirectly projects images into the curved material. ### Claim 4 (depends on 1) The gaming system of claim 1, wherein the touch panel is curved. ### Claim 5 (depends on 1) The gaming system of claim 1, wherein the touch screen system is configured to initiate the spinning of the one or more reels of the game. ### Claim 6 (depends on 1) The gaming system of claim 1, wherein the touch screen system is configured to add or remove one or more images of the reels from the curved display. ### Claim 7 (depends on 1) The gaming system of claim 1, wherein the touch screen system is configured to swap game indicia between reels. ### Claim 8 (depends on 1) The gaming system of claim 1, wherein the touch screen system is configured to add or remove game indicia from the reels. ### Claim 9 (depends on 1) The gaming system of claim 1, further comprising a secondary display distinct from the curved material, wherein the digital light projection projects one or more images onto the secondary display. ### Claim 10 A gaming system using touch panels as user control devices, the system comprising: a curved display system for displaying a game, the curved display system comprising a curved material having an outer surface, an inner surface, and a radius of curvature similar to a mechanical reel, and a digital light projection device for projecting images of one or more reels onto the curved material; and a touch screen system positioned in front of the curved material, the touch screen system comprising a touch sensor assembly having a touch panel that produces touch data when activated, the touch panel having an opening, a touch panel controller for controlling and interpreting the touch data, and touch panel software for controlling and interpreting touch data, wherein the curved material extends through the opening in the touch panel. ### Claim 11 (depends on 10) The gaming system of claim 10, wherein the digital light projection device directly projects images into the curved material. ### Claim 12 (depends on 10) The gaming system of claim 10, wherein the digital light projection device indirectly projects images into the curved material. ### Claim 13 (depends on 10) The gaming system of claim 10, wherein the touch panel is curved. ### Claim 14 (depends on 10) The gaming system of claim 10, wherein the touch screen system is configured to initiate the spinning of the one or more reels of the game. ### Claim 15 (depends on 10) The gaming system of claim 10, wherein the touch screen system is configured to add or remove one or more images of the reels from the curved display. ### Claim 16 (depends on 10) The gaming system of claim 10, wherein the touch screen system is configured to swap game indicia between reels. ### Claim 17 (depends on 10) The gaming system of claim 10, wherein the touch screen system is configured to add or remove game indicia from the reels. ### Claim 18 (depends on 10) The gaming system of claim 10, further comprising a secondary display distinct from the curved material, wherein the digital light projection projects one or more images onto the secondary display. ### Claim 19 A gaming system using touch panels as user control devices, the system comprising: a curved display system for displaying a game, the curved display system comprising a curved material having an outer surface, an inner surface, and a radius of curvature similar to a mechanical reel, and a digital light projection device for projecting images of one or more reel strips onto the curved material; and a touch screen system positioned in front of the curved material, the touch screen system comprising a touch sensor assembly having a touch panel that produces touch data when activated, the touch panel having an opening, a touch panel controller for controlling and interpreting the touch data, and touch panel software for controlling and interpreting touch data, wherein the touch screen system is configured at least for adding reel strips to the game, removing reel strips from the game, adding game indicia to the reel strips, or removing game indicia from the reel strips, and wherein the curved material extends through the opening in the touch panel. ### Claim 20 (depends on 19) The gaming system of claim 19, wherein the touch panel is curved. ### Claim 21 (depends on 19) The gaming system of claim 19, wherein the touch screen system is configured to swap game indicia between reels. ### Claim 22 (depends on 19) The gaming system of claim 19, wherein the touch screen system is configured to initiate the spinning of the one or more reels of the game. ### Claim 23 (depends on 19) The gaming system of claim 19, further comprising a secondary display distinct from the curved material, wherein the digital light projection projects one or more images onto the secondary display.
