Claims (44)

1. An electronic gaming machine comprising:

a housing;

a reel assembly supported by the housing, the reel assembly comprising a plurality of reels;

a plurality of dividers supported by the housing and extending between the plurality of reels, wherein one of the dividers comprises:

a member comprising a front side and a back side,

a first layer comprising a coat of a first color on the back side of the member,

a second layer comprising a coat of a second color on a back side of the first layer and at an area of a hidden symbol of the member, and

a third layer comprising a coat of the first color on a back side of the second layer at the area of the hidden symbol; and

back lighting supported by the housing and configured to selectively illuminate the hidden symbol to make the hidden symbol visible to a player at a first time and to make the hidden symbol not visible to the player at a subsequent second time.

2. The electronic gaming machine of claim 1 , wherein the first color is white.

3. The electronic gaming machine of claim 2 , wherein the second layer comprises multiple coats of the second color.

4. The electronic gaming machine of claim 3 , wherein the third layer comprises multiple coats of the first color.

5. The electronic gaming machine of claim 1 , which comprises front lighting configured to selectively illuminate the member at a first intensity level and to lower the first intensity level to co-act with the back lighting to make the hidden symbol visible to the player.

6. The electronic gaming machine of claim 5 , which comprises front lighting configured to selectively illuminate the member at the first intensity level to make a non-hidden symbol on the member visible to the player and to make the hidden symbol not visible to the player.

7. An electronic gaming machine comprising:

a housing;

a reel assembly supported by the housing, the reel assembly comprising a plurality of reels; and

a plurality of dividers supported by the housing and extending between the plurality of reels, wherein one of the dividers comprises:

a member comprising a front side and a back side,

a first layer comprising a coat of a first color on the back side of the member,

a second layer comprising a coat of a second color on a back side of the first layer in an area where a hidden symbol is formed in an integrated manner with a non-hidden symbol,

a third layer comprising a coat of a third color on a back side of the second layer except at the area of the hidden symbol, and

a fourth layer comprising a coat of a fourth color on a back side of the third layer except at the area of the hidden symbol and the non-hidden symbol.

8. The electronic gaming machine of claim 7 , wherein the first color is white.

9. The electronic gaming machine of claim 8 , wherein the fourth color is black.

10. The electronic gaming machine of claim 7 , wherein the first color and the third color are a same color.

11. The electronic gaming machine of claim 7 , wherein the third layer is also on the first layer.

12. The electronic gaming machine of claim 11 , wherein the fourth layer is also on the third layer.

13. The electronic gaming machine of claim 7 , which comprises back lighting configured to selectively illuminate the hidden symbol to make the hidden symbol visible to a player.

14. The electronic gaming machine of claim 13 , which comprises front lighting configured to selectively illuminate the member at a first intensity level to make a non-hidden symbol on the member visible to a player and to make the hidden symbol not visible to the player.

15. An electronic gaming machine comprising:

a housing;

a reel assembly supported by the housing, the reel assembly comprising a plurality of reels; and

a plurality of dividers supported by the housing and extending between the plurality of reels, wherein one of the dividers comprises:

a member comprising a front side and a back side,

a first layer comprising a coat of a first color on the back side of the member with an opening for a non-hidden symbol of the member,

a second layer comprising a coat of a second color on the back side of the member in the opening,

a third layer comprising a coat of a third color on a back side of the first layer and a back side of the second layer except in an area of a hidden symbol of the member, wherein the hidden symbol has no color, and

a fourth layer comprising a coat of a fourth color except in the area of the hidden symbol.

16. The electronic gaming machine of claim 15 , wherein the first color is white.

17. The electronic gaming machine of claim 16 , wherein the second layer does not comprise any opposing color to the first color.

18. The electronic gaming machine of claim 16 , wherein the fourth color is black.

19. The electronic gaming machine of claim 15 , wherein the first color and the third color are a same color.

20. The electronic gaming machine of claim 15 , which comprises back lighting configured to selectively illuminate the hidden symbol to make the hidden symbol visible to a player.
