This new game on Konami’s Concerto cabinet is the latest in the “Xtra Reward” series, which features a variety of mystery and free-spin bonus features. In this instance, those features and the theme center around a golden submarine that serves as the wild symbol.
The submarine symbol appears on all reels during the base 40-line game. (It is also available to casinos in 10-line, 15-line, 20-line or 30-line configuration.) It substitutes for all but the anchor symbol, which is the bonus trigger symbol.
When the wild submarine lands on the fifth reel, a mystery wild feature may add wild symbols to several other positions on the screen. Some of the extra wild symbols contain an anchor, and thus substitute for the bonus trigger symbol. This feature is more frequent during the free-spin bonus round.
The game also features Konami’s “Action Stacked Symbols.”
Randomly, a symbol will multiply into a stack of symbols—that includes wild symbols and bonus triggers.
Three, four or five anchor symbols trigger eight, 12 or 20 free games, respectively. If the Wild Feature is triggered by a submarine on the fifth reel during free spins, another mystery feature may be triggered—a submarine will cross the screen and arrange all added wild symbols into a straight line on one payline, usually for an easy winning combination.
The Wild Feature can occur throughout the free games, and additional free games can be awarded.
Submarine Victory is a KP3+ platform game available exclusively on Konami’s Concerto cabinet lineup, including Concerto upright, Concerto Slant and Concerto SeleXion multi-game.
