Silent Run is a five-reel 25-payline video slot themed around WW2 submarines that sank enemy warships, caused havoc and inspired fear. As the number of paylines comes fixed, you may set a coin denomination ($0.01–$0.5) and a bet level (1–10), thus, the minimum and maximum stakes are $0.25 and $125 a spin. The first, second and third largest prizes are $5000 (five Submarines), $3750 (five Warships) and $2500 (five Torpedoes symbols).

Bonus features

The Alarm Lamp acts as a wild that substitutes for all normal icons and helps create winning combinations. There is also an Echo wild symbol that looks like a red radar screen. When the Echo wild lands on reel 3, it begins to scan the reels and transforms up to three random symbols into regular wilds.

A green radar display appearing on reel 3 initiates a captivating bonus game played on the second screen. Before you enter the game, the green radar sends a few signals across the reel field and finds 2 to 5 torpedoes. After that you will find yourself on board a submarine preparing to perform a torpedo attack by selecting one of five targets and firing a torpedo. The number of torpedoes you may shoot will be equal to the number of torpedoes that were pinned down with the green radar in the latest main game. Each hit gives you a random coin award multiplied by the value that is displayed on the screen and increases with each subsequent torpedo launch (up to a maximum of x10). One of the five target ships gives an extra-large win, if hit.
