Wilds
The main wild symbol is a red warning light that substitutes all symbols except the Echo Wild. The Echo Wild appears on reel 3, sending out 3 sonar bursts that reveal hidden wild symbols to help boost your winning lines.
Echo Bonus
Similar in appearance to the Echo Wild, if you manage to find an Echo Bonus symbol on reel 3 then you’ll be able to play the bonus game. Using the periscope you are tasked with choosing enemy ships to fire your torpedoes on. Its possible to get up to a 10x multiplier during this mode with each successful torpedo hit adding to the multiplier. Players are able to win up to 250,000 coins! Therefore you can expect a decent pay out compared to a lot of other click and pick features.
Our verdict
Silent Run is a well-made slot but outside of its fun bonus mini-game and war theme, there aren’t too many reasons why we think you’d choose it over a different slot. There are some good incentives such as the multipliers but if you aren’t hitting the bonus round then you’ll most likely want to choose a slot with more features.
