5 reels, 3 rows and 20 fixed lines. Matching symbols pay left to right on a line, starting on reel 1, 3 or more in a row. Your bet is spread over all 20 lines. All wins are in credits (25¢ each).
The Gold Nugget lands on reels 2, 3 and 4 and stands in for every symbol except the Mine Cart and the Dynamite.
Credits are play money only. The attendant adds credits. CASH OUT prints a ticket the attendant pays.
