The Boost symbol in combination with any Bonus symbol triggers the Boost Feature. The Boost Feature sums up the values of the Bonus symbols and adds them to the winning for the spin. Boost symbols may land in any game mode and appear in the following way:
6+ Bonus symbols or their combination with the Boost symbol trigger the bonus game.
The payment is indicated on the symbol in currency: x1, x2, x3, x4, x5, x6, x7, x8, x9, x10, x15 bets. All Bonus symbols remain on the reels during the Bonus Game. At the beginning of the Bonus Game, 3 re-spins are provided. Each new Bonus, Boost or Mystery symbol resets the number of re-spins to 3. The Bonus Game continues until the player runs out of re-spins or all the cells on the reels are filled with Bonus symbols. When the Bonus Game ends, the values of all Bonus symbols are summed up and the Total Win is paid.
Mystery symbol appears only during the Bonus Game and transforms randomly into Mini, Minor or Major Jackpot symbols. During the Bonus Game several Mystery symbols may land on the reels. Mystery symbols are revealed one-by-one at the end of the Bonus Game or right after the spin if the Boost symbol is present.
Any Bonus symbol landing on the reels during the Main Game or Free Spins grants a chance of triggering the Treasure Chest Feature, which adds enough Bonus symbols (or more) to activate the Bonus Game.
