Big Bonus Booster plays on a 6x4 reel set and uses 40 win lines. A bonus Match 3-like gamemode, sticky Wilds and potential huge Free Spins are just icing on the cake. Winning combinations range from three to six matching symbols alone active win lines in all game modes except of course the Match 3 bonus feature. Fortune Bets and Gamble modes are also present, making Big Bonus Booster a tremendous addition to our slot catalogue here on Admiral Casino UK.

Big Gem Bonus

Bonus symbols may appear everywhere during base rounds. Having at least three of them appear will trigger the Big Bonus feature, with starting values determined beforehand by the Match 3 - Pick Me feature play.

  • Three Bonus symbols will offer bonus values from 20x, 25x, 30x, 50x or 100x
  • Four Bonus symbols will offer bonus values from 25x, 30x, 50x or 100x
  • Five Bonus symbols will offer values from 30x, 50x or 100x
  • Six Bonus symbols will determine bonus values of either 50x or 100x

Match 3 Pick Me

This feature will allow players to pick their Big Bonus values. The screen will show six, nine, 12 or 15 identical tiles, their number scaling with the number of bonus symbols that triggered the feature play in the previous round. Players can flip tiles one by one to uncover big shiny gems of different colours. Once three matching gems have been uncovered, their assigned bonus value and bonus trail will be used to commence the Bonus play with.

Big Bonus Booster Free Spins

Free Spins start with the bonus value and bonus trail progress determined by the Pick Me - feature. Anytime Big Bonus Booster gems land on the last reel, the state of the trail will be advanced. Anytime the trail is completed, the Big Bonus value will be upgraded. Any Wilds appearing during these Free Spins will lock in place for the remainder of the Free Spins game mode. The game mode ends only once a total prize value equal or bigger than the current Big Bonus values accumulated.

Big Bonus Booster Fortune Bet

Any win larger than 5x your total bet can be gambled with as long as the Gamble feature had been activated prior. Choosing to gamble allows players to pick from two wheels, one with segments showing multipliers of half, double or triple, while the right wheel offers up segments allowing access to Free Spins directly.
