Silent Run is a 5 reel, 25 payline NetEnt slots game that takes its inspiration from the world of submarine warfare, with themes that will be appealing and familiar to fans who remember the tense, atmospheric feel of the classic movie and novel, The Hunt for Red October, although the game is no way linked with that property.

With an added bonus game and a host of interesting features, Silent Run is a solid addition to NetEnt’s host of online slots.

Look and Feel

The atmospheric soundtrack combines quiet ambient sounds that give the feeling of being underwater in a submarine with dramatic musical stings to announce wins, accompanied by sonar blips and a clean UI design with a slight mid-to-late twentieth century retro feel.

Lower value symbols are alphanumeric, while the higher value symbols are represented by torpedos, mines, depth charges, battleships and the submarine itself. The game has a red light Wild, which can substitute for all symbols except the Echo Bonus and Echo Wild symbols.

The Echo Wild is a red radar screen, and gives players the chance to unlock hidden wild symbols, potentially revealing even bigger wins.


Silent Run has a minimum bet of 25p, with a ceiling of £125 per spin. There is a clear, simple interface ideal for mobile device or desktop/laptop gameplay, and bets are controlled through the “Level” and “Coin Value” selectors.

There are max bet and autoplay options, and autoplay can be stopped early if the player wishes. Maximum coin value is 0.50.

Silent Run offers up to 25 paylines over its five reels and three rows, but it’s the innovative bonus features that really set this title apart.


Silent Run has the standard Wild symbol you would expect: a red light that can substitute for any symbol except the Echo Bonus and Echo Wild symbols, and contributes to unlocking the mini game.

The red radar screen Echo Wild appears only on reel three, and will send out three sonar pulses, revealing any “hidden” Wilds on the reels.

The green radar screen Echo Bonus symbol, which also appears only on reel three, activates the bonus game, which takes players to an “up periscope” second screen, where they must target battleships on the ocean.

Each ship targeted will unlock a coin bonus, which is calculated at the end of the game.

This feature triggers quite regularly, and is a welcome fresh and unusual addition that makes Silent Run a memorable slots experience.
