Big Bonus Slot Game Background

Big Bonus is the first in a particular series of slots from Inspired Gaming to fuse classic fruit machine aesthetics with modern mechanics that include multipliers, sticky symbols and a thrilling Free Spins bonus round, creating an immersive and interactive player experience.

Big Bonus Slot Game Design

Big Bonus is a 6-reel, 4-row UK casino game with 50 paylines and a potential maximum payout of 12,500x the stake. The action takes place against a starry green background with light streams exploding from behind the game grid. Regarding the game grid, this is encased in a thin golden frame and dominates most of the in-game screen. The reels themselves are an elegant blue colour and house symbols inspired by the classic fruit slots, such as plums, oranges, lemons etc.

Big Bonus does not feature any music in between spins. However, the slot does boast music and ambient sound effects when spinning the reels, including an upbeat jingle-type ditty when winning a significant cash prize alongside other ambient sounds. The biggest musical change comes during the Free Spins bonus round. An electronic synthesiser-type score plays when picking a multiplier while the bonus round itself features an upbeat dance-inspired soundtrack.

Big Bonus Slot Mobile

Big Bonus, like all the online slot games available at Lottomart Games, is available to play on mobile devices and tablets while on the move alongside desktop PCs at home. You can also download the Lottomart app via a stable internet connection or mobile data for the best experience possible.

The game has 12 symbols, all fitting the modern spin on the classic fruit slot theme to a tee.

  • Grapes, orange, lemon and cherries =these symbols have a payout of 5x the stake for 6-of-a-kind on the reels.
  • Plum and watermelon =these symbols have a payout of 8x the stake for 6-of-a-kind on the reels.

  • Crown = this symbol has a payout of 20x the stake for 6-of-a-kind on the reels.

Other Symbols

  • Wild symbol = represented by the word WILD on an elegant blue background, this symbol appears on all reels during the base game and on reels 2, 3, 4, 5 and 6 substitutes for all other ones apart from the Bonus Scatter.
  • Bonus Scatter symbol = represented by the word BONUS with golden stars streaming above it, this symbol appears on all reels and is the key to triggering the game’s Free Spins bonus feature.

Big Bonus Slot Bonus Features

The main special feature in Big Bonus is the Free Spins bonus round. It's triggered by landing 3 Bonus Scatter symbols in view.

A gold-rimmed PICK ME symbol appears for every Bonus Scatter symbol in view. Behind each PICK ME symbol is a multiplier to be awarded to the player. The range of possible multiplier values is: 20x, 25x, 30x, 50x or 100x.

The number of multipliers shown during the reveal may not necessarily be proportionate to the number of multipliers awarded in the bonus feature.

Select a PICK ME symbol to reveal the multiplier value behind it. The Free Spins feature then starts.

Unlimited Free Spins are in play until a win greater than or equal to the multiplier value picked happens.

Any Wild symbols that land during the Free Spins bonus round lock in place and remain in place until the end of the feature.

Big Bonus Slot Summary

Big Bonus sets the stage with an impressive debut for the Big series of slots. It successfully meshes what makes the old-school fruit machine slots the classics that they are with modern features and bonuses while keeping a stylish and elegant presentation.

Enjoy this slot and want to see other titles we have on-site? Check out the other slots in the Big series of games, including Big Spin Bonus and Big Wheel Bonus.

However, if you want to branch away from this particular franchise of online slot games, we have a great selection of alternative titles to potentially choose from, each of which adopt their own unqiue theme. One of these which we recomend is the Gonzo's Quest slot game which presents a rather distinctive conquistador theme!
