Katana is a Novomatic slot machine with five reels, three rows and up to 20 lines that can be selected for every spin. The game is one of the better looking titles created by the software provider and its theme promotes an action-packed gameplay, while the rewarding features will ensure big prizes are part of every session. The style of the game is influenced heavily on elements from the history of Japan and samurai characters can be found on the reels, as well as their iconic weapons, known as katana. The list of symbols starts with the substitute icon which is the skilled samurai master, or the Shogun, and as all wilds, this symbol will be able to play the role of any of the regular symbols when it can help create a winning combination on the active lines. An image of the katana is the scatter and this is very valuable since it pays regardless of its position on the screen, with big prizes, and can trigger the free games mode plus the Shogun Bonus. Three or more scatters are needed to trigger 10 free spins and this feature can be retriggered for additional spins of the reels on the initial bet. During the free spins, the wild symbols will expand to cover all the position on the reel. The other symbols show a beautiful geisha, the samurai leader, archers, Japanese temples and five card symbols in different colors which cover the lower paying part of the paytable. The Katana slot also comes with a “gamble” feature where players can opt to enter their winnings from a regular spin and try to double it by guessing the color of a random card. This can be done several times, with the total amount being multiplied by two with every correct guess; while an incorrect choice will forfeit the amount.
