Features worth trying
- Chance x2
A player can buy Chance x2 in the main game. It slightly increases the bet and gives the player more chances to hit free spins. The feature is disabled if the Buy Bonus feature is active.
- Buy Bonus
Players can trigger the Free Spins round by buying it at a price pictured on the button. The Buy Bonus price will be automatically adjusted if a player changes the bet. The feature is disabled if the Chance x2 feature is active.
- Multiplier symbol
During both the base game and Free Spins round, a player can hit Multiplier symbols from x2 to x500. They stay on the screen until the end of the refilling sequence, and then their values are summarized and multiply the total win. In free spins, the dropped multipliers are summed and accumulated. All the multipliers from winning spins are added to one common multiplier, which is then applied to subsequent winning spins during the Bonus round.

Extra reel
There is an extra reel positioned beneath the main 5×5 field. This extra reel displays 5 additional symbols during each spin that complete or enhance winning combinations.
Refilling
The Refilling feature can give players many consecutive wins on every spin. It works by paying out all matching combinations and removing winning symbols after every spin. Then, the empty cells are filled with symbols coming from above. Refilling continues limitless until no more winning combinations appear. Winnings are credited to the player’s balance after all refills from a base spin have been played.
Symbols pay anywhere on the screen
The total number of the same symbol at the end of a spin determines the win value.
