Silent Running has an exciting bonus game. This echo bonus game symbol appears on the third reel of the game. The echo bonus releases 3 sonar signals to find torpedoes. There are 2 to 5 kinds of torpedoes. The torpedo has a multiplier that sinks the ship, and different ships have different values to help determine the rewards of the reward game. The player's bonus is equal to the value of the ship times the torpedo multiplier. The Silent Run Wild symbol can be found on reels 1, 2, 4, and 5. These Wilds can replace any symbol except Echo Bonus and Echo Wild. The Echo Wild symbol is only available on Reel 3.
