With a reel configuration of 6×4 and 50 win-lines, Big Bonus Booster incorporates regular base game wins with an abundance of classic slot symbols and fun Wilds. Landing three Bonus symbols in the base game awards players the Big Bonus Match 3 Pick Me game. Choosing three of the same gems determines the player’s Big Bonus multiplier value and marks their positions on the Boost Trail.
The game offers a plethora of features, including Bonus Bet, Bonus Game with object picking, Multipliers, a Risk/Gamble Double game, and Wild symbols, ensuring diverse opportunities for winning combinations. The theme exudes a classic charm with a modern twist, making it appealing to both traditional and contemporary slot enthusiasts.
The symbols include various types of fruits typical to classic fruit slot machines. They include cherries, lemons, oranges, and grapes. The slot also includes three different lucky number 7’s in its paytable.
Besides the regular characters, there is also a special wild that substitutes for all other symbols except the scatter, which activates the Big Bonus free spins round.
The in-game menus and controls are nice and easy to understand and it's really easy to get started. The game doesn't feature a soundtrack as such, but frequent sound effects accompany each play and wins.
When a player successfully lands 3 or more scatter symbols on the reels, the Big Bonus feature will be triggered, allowing the player to choose a 'big bonus win value'.
The player then enters an unlimited free spins game which features sticky wild symbols. Each wild landed successfully will be fixed in place until the end of the bonus game, giving the player further chances to win in subsequent spins. The aim is to continue spinning until you have exceeded your chosen big bonus value in a single spin.
There is also a Spin Chance feature that launches automatically if the player balance reduces below the current price of play, but is still more than zero. It’s an added advantage for players to gamble their remaining bankroll in an attempt to win an extra spin at the playing stake.
