Claim:
1. A gaming system comprising: a presentation module that presents in a display area selected symbols from first and second symbol reels provided with respective first and second sets of symbols, an outcome determination module that determines an outcome based on a first win line symbol from the first set of symbols of the first symbol reel positioned along a win line in the display area and on a second win line symbol from the second set of symbols of the second symbol reel also positioned along a win line in the display area, wherein the outcome determination module determines whether or not a user of the gaming system has won a prize, and if so, the prize the user has won based on an initial symbol arrangement formed from the first and second win line symbols positioned along the win line in the display area, without the first and second win line symbols being replaced by other symbols, an outcome replacement module which is different from the outcome determination module, and which is activated by an input from the user so as to always select both a first replacement symbol for the first win line symbol and a second replacement symbol for the second win line symbol, and thereby cause the outcome determination module to determine whether or not the user has won a prize, and if so, the prize the user has won based on a replacement symbol arrangement formed from the first and second replacement symbols, the first and second replacement symbols being located an equal distance from the first and second win line symbols, respectively, along the first and second symbol reels, respectively, the equal distance being chosen such that the first and second replacement symbols are not among the symbols in the display area with the first and second win line symbols, and a payment module through which the user provides a coin, paper money and/or credit card payment to use the gaming system and by which the gaming system delivers a winning payment to the user when the outcome determination module determines whether or not the user has won a prize, and if so, the prize the user has won based on either the first and second win line symbols or the first and second replacement symbols being part of the initial or replacement symbol arrangement used by the output determination system to determine that the user has won a prize, whereby activation of the outcome replacement module by the user allows the user to seek an extra chance of winning based on the selected first and second replacement symbols.
