To provide a large winning device preventing a game ball from easily enter a large winning hole when a short jackpot or minor jackpot is won but allowing a game ball to easily enter the large winning hole when a long jackpot is won.

The large winning device includes: an eave 4 disposed above the large winning hole 3 for guiding downward-flowing game balls sideways avoiding the large winning hole 3; and a retractable member 6 disposed below the large winning hole 3 and having the horizontal length exceeding the large winning hole 3. The retractable member 6 is configured to be freely moved between a projecting position where the retractable member projects forward from a slit formed on the front surface of a base member 2 below the large winning hole 3 and a retracted position where the retractable member is retracted into the slit. The retractable member has a game ball holding part 7 for temporarily holding a game ball flowing down from above when the retractable member 6 is located at the projecting position. The game ball held by the game ball holding part 7 interferes with the front surface of the base member 2 and falls down when the retractable member 6 is retracted from the projecting position to the retracted position.
