The present invention provides a system and method for playing a betting game in which a player selects at least one betting line. The player-selected betting lines correspond to particular cells on a game board. Each cell on the game board is assigned a randomly selected spinner icon. The spinner icons within cells corresponding to a selected betting line are evaluated to determine if a winning condition as defined in a payout table has been achieved. A winning condition occurs when a predetermined minimum number of identical icons in the one or more player-selected betting lines are displayed. If a bonus feature icon is displayed by at least one of the cells, a bonus feature is automatically activated enabling the player to earn additional winnings. The present invention may be configured as a slot machine and provided within a gaming establishment. Additionally, the present invention is also configurable as an online betting game playable over a network or as a user-installable program installable on a personal computer or other such computing device.
