Changing technology has changed the way slot machines are played. Most machines with multiple pay lines allow players to choose how many lines they want to play. The minimum bet is only one line across the reels. For more money, you can play additional horizontal and vertical lines above and below the main pay line. Additionally, some machines have diagonal lines running across the reels. However, you can only win the maximum jackpot if you bet the highest amount.
