About this Slot
Final Boss is an action and adventure sci-fi slot with six reels, five rows and ways to win. The RTP is 96.5% with high volatility and a maximum win of 20,000x.
Reels 2 through 5 have a split strip that duplicates symbols, expanding the number of winning ways on each spin. Duplicated symbols remain in place until the cascade sequence ends or the spin concludes. Winning symbols clear and fall, with new symbols entering from the top to form fresh combinations. Cascades repeat until no additional wins are formed.
A global multiplier begins at 1x and increases by 1x with each cascade. This multiplier applies only to wins using all six reels, and locks in place once a six-reel win occurs for the remainder of the spin.
Three scatter symbols trigger the bonus round, awarding 8 Free Spins. During this feature, the multiplier resets to 1x after any six-reel win.
Landing both P1 on reel 1 and P2 on reel 6 triggers the Super Bonus. The feature begins with a fight sequence, and the winner's multiplier becomes the global multiplier for the remainder of the bonus. This multiplier does not reset during the feature.
Landing P1, P2 and three scatters together triggers the Epic Bonus. The feature opens with a fight where the winner starts with a minimum multiplier of 25x. One bare wild symbol is added each spin, with an additional wild added whenever a winning cascade occurs.
Extra Chance costs 3x the bet and increases bonus trigger chances by 5x, though it does not guarantee a bonus. Hyper Spin costs 6x the bet and makes bonus triggers 10x more likely, functioning as a separate booster without altering the core game.
Bonus buy costs 100x the bet and awards 8 Free Spins, with the multiplier resetting after six-reel wins. Super Bonus buy costs 250x the bet and starts the fight immediately with the winning multiplier in place. Mystery Bonus buy costs 500x the bet and returns one of three outcomes: no bonus, the Super Bonus, or the Epic Bonus.
