Fruit machines are coin-operated devices with three or more spinning reels. These reels have various pictures on them, usually fruit (including the iconic cherries). The aim of the game is to spin the reels and create combinations of these symbols, with prize money won according to the combination created. Fruit machines are popular because of their relatively high payout rate when compared with other forms of game machines. When fruit machines payout, they typically return between 70-98% of money gambled. (資料來源)
Many fruit machines have a ‘hold’ button. This lets you pause certain reels during play, increasing the chances of winning. For example, if you had two lemons in a row, you could hit ‘hold’ and continue spinning the remaining reel in the hope of getting another lemon. Some fruit machines also have a ‘cancel’ button. Hitting this button during play slows the reels down, helping you spot patterns and making it easier to find the pictures you need to win. This process is known as ‘wedging’. (資料來源)
