4. The gaming machine of claim 1 , wherein the first condition is a condition that a second predetermined symbol is rearranged on a predetermined position of the first display.

5. The gaming machine of claim 1 , wherein the plurality of chance types include at least one chance type for showing a sign of the bonus mode game being triggered, and

wherein the controller is configured to show the sign of the bonus mode game being triggered, by opening or closing of the door and displaying an object image on the display panel.

6. The gaming machine of claim 1 , wherein the plurality of chance types include at least one chance type for showing a probability of the bonus mode game being triggered, and

wherein the controller is configured to show the probability of the bonus mode game being triggered, by controlling opening or closing of the door and displaying a predetermined image on the display panel.

7. The gaming machine of claim 6 , wherein the predetermined image is varied according to the probability of the bonus mode game being triggered.

8. The gaming machine of claim 1 , wherein the plurality of chance types include at least one chance type for providing additional benefit.

9. The gaming machine of claim 1 , wherein the benefit according to the first predetermined symbol includes a bonus mode game including a plurality of free rounds, and

wherein the second condition is a condition that a number of the first predetermined symbols is equal to or greater than a predetermined number in the rearranged symbols.

10. The gaming machine of claim 9 , wherein the memory is configured to further store a plurality of third tables for determining symbols to be rearranged on the first display in the bonus mode game having a plurality of bonus types, and

wherein the controller is configured

to determine a bonus type among the plurality of bonus types in the bonus mode game,

to select a third table corresponding to the determined bonus type among the plurality of third tables,

to execute each free round of the bonus mode game according to the determined bonus type to rearrange the symbols based on the selected third table, and

to provide a benefit according to rearranged symbols.

11. The gaming machine of claim 10 , wherein the controller is configured to open the door and display an image for notifying the determined bonus type on the display panel.

12. The gaming machine of claim 9 , wherein the controller is configured to trigger the bonus mode game when the arranged symbols satisfy the second condition in the normal mode game.

13. The gaming machine of claim 12 , wherein the memory is configured to further store a plurality of second rendering pattern data corresponding to a plurality of rendering patterns for the normal mode game,

wherein the controller is configured to determine a rendering pattern among the plurality of rendering patterns, and to show a sign of the bonus mode game being triggered by controlling opening or closing the door and displaying an object image on the display panel based on a second rendering pattern data that corresponds to the determined rendering pattern among the plurality of second rendering pattern data.

14. The gaming machine of claim 1 , wherein the door includes a left sliding door configured to be opened in a left direction from a center position for the door and a right sliding door configured to be opened in a right direction from the center position.

15. A gaming method by a gaming machine including a first display and a second display, the second display including a display panel and a door located in front of the display panel and configured to control opening or closing of the door to control an exposure of the display panel, the method comprising:

executing a normal mode game to rearrange symbols on the first display, based on at least one first table for determining symbols to be rearranged in the normal mode game;

triggering a chance mode game including a plurality of chance rounds when the rearranged symbols satisfies a first condition;

determining a chance type of the chance mode game among the plurality of chance types;

executing each chance round of the chance mode game to rearrange the symbols based on a second table for the determined chance type among a plurality of second tables, by controlling opening or closing of the door and displaying an object image on the display panel according to the determined chance type, wherein a probability of a first predetermined symbol being determined in each second table is higher than a probability of the first predetermined symbol being determined in the first table; and

providing a benefit according to the first predetermined symbol to a player when the rearranged symbols satisfy a second condition defined by the first predetermined symbol in a certain chance round.

16. The method of claim 15 , further comprising ending the chance mode game and returning to the normal mode game when a number of chance rounds executed in the chance mode game is equal to a threshold.
