A gaming machine for playing a multi-line spinning reel game has a display and a game controller arranged to control images of symbols displayed on the display. In the game at least one random event, in particular a spin of the reels, is caused to be displayed on the display. If a winning event occurs the machine awards a prize. The player is constrained to wager a single amount on each play of the game and may not vary the amount. This single wager amount provides eligibility to play all available lines of the game and eligibility to bonus features. No choice of other wagering options is provided.
