Silent Run is a slot machine with 5 reels and 25 fixed bet lines inspired by the battles of the Pacific Ocean during World War II. The setting is in fact that of a submarine as it makes its way around the mines and gets in position to fire torpedoes on the enemy fleet. Silent Run presents symbols for Wild, Wild Echo, Echo Bonus and finally the Bonus Game. The Wild symbol, as usual serves as a substitute for all other symbols except for the two Echo icons, to create the best possible combination. The Echo Wild symbol, represented by red radar, has the power when it appears on reel 3, to fathom all rollers looking for other hidden wilds. Always on the roller 3 may appear another Echo symbol, or the Echo Bonus, represented by the green radar. This symbol in turn will scan the area of the rollers in search of torpedoes, from 2 to 5, which will then be used in the bonus game to sink enemy ships. For each vessel demolished, the game pays a premium, which in turn is multiplied by the multiplier indicated on each missile and that increases with each hit ship. The player is given the option to select the enemy ship on which to fire. The regular wild symbol in Silent Run is the red light indicating the alarm on board of the submarine. Other symbols show great depictions of a submarine under water, a battleship, torpedoes on their way to their targets, water mines and diving bombs. There are also five card symbols added in order to make sure the game has a complete list of icons. It is easy to see that the game is very well made and the attention to detail really makes it stand out, not to mention the special features and the chance to win up to 250,000 coins from just one bet.
