Love playing bingo and slots? Then Slingo Big Spin Booster is exactly what you need. Read our Slingo Big Spin Booster slot review to find out all about this game by Gaming Realms. This single-reel game grid offers a unique gameplay with a multi-tiered bonus system. The circus-themed slot is presented as a Wheel Money Spinner, has a 5x5 grid like a bingo card, and a single spinning reel beneath it. You mark matching numbers on the grid with those on the reel, unlike standard slot machines, where winning combinations are determined by paylines. The goal is to create a complete line, known as a ‘Slingo’, either diagonally, vertically, or horizontally. You will access a tiered progression system that includes bonus games inspired by ducks and cannons. The bonus system has a multi-layered structure, which includes Boom Brothers Bonus, Quack Shot Bonus, and a unique Jackpot Wheel with rewards up to 3000x the initial game stake. With an RTP of 95.46%, this moderately volatile game requires you to take a strategic approach while playing, thanks to extra spins and Wild placement features. Rise up the pay ladder with multiplier values that offer increasing potential rewards when combined with wheel multipliers.

Slingo Big Spin Booster Bonus Features

Although Slingo games are not known for their supplementary features, Slingo Big Spin Booster is loaded with bonus features that can completely transform your gaming experience. 

  • Wild and Super Wild: Wilds are used to mark off different symbols in the column above. Super Wilds enable you to mark off any number you want. 
  • Bonus Spin: Although the game is played in 10 spins, the Bonus Spin symbol will award you an additional spin. 
  • Scatter: If you can land three or more scatters, it will trigger the scatter wheel to spin. It can award instant win multiplier prizes that can range from 2-3000x the total bet.
  • Scatter Wheel: You can receive reward multipliers ranging from 2-15x the total bet by landing a scatter wheel.
  • Major Scatter Wheel: The Major Scatter Wheel is awarded for landing four scatters, and this can pay out prizes ranging from 10-75x the total stake.
  • Grand Scatter Wheel: The Grand Scatter Wheel is given upon landing four scatters, and can lead to rewards ranging from 400-3000x the total bet.
  • Extra Spins: You can buy additional spins when the main game ends. The price of extra spins depends on the current state of play. You cannot activate bonus games during extra spins.
  • Bonus Wheel: You can unlock either the Wheel Boost or the Cash Wheel feature by completing 4 Slingos. However, by completing 5 Slingos, you can unlock the Quack Shot Bonus (the duck-themed reward feature), along with the two features mentioned above. Completing 6-10 Slingos will grant you the Boom Brothers Bonus (the cannon-themed reward feature) and the other three aforementioned bonus features. Achieving all 12 Slingos will grant you the Boom Brothers Bonus, Quack Shot Bonus, Cash awards, and the Jackpot Bonus Wheel.
  • Wheel Multiplier: The wheel multiplier will be multiplied by the number of Slingos completed to get the final payoff. Hence, 5 Slingos with a minimum multiplier of 3x will lead to a total payout of 15x, 5 Slingos with the highest multiplier of 15x will award 75x, and so on.
  • Quack Shot Bonus: This duck-themed pick-a-prize bonus has 3 different duck symbols, including the brown duck, the white duck, and the yellow duck, with separate rewards. You will have the opportunity to select a single option for your reward, even though the outcome is selected randomly.
  • Boom Brothers Bonus: Similar to the Quack Shot bonus, this is another pick-a-prize bonus feature with a cannon theme. The Boom Brothers bonus can unlock higher rewards as each specific cannon, including the brown cannon, silver cannon, and the orange-red cannon, delivers different rewards, with the premium cannon offering prizes up to 2,250x the initial stake.
  • Boost: This feature upgrades all Cash prizes and bonuses to the next Slingo level. It also offers you an extra spin. Upon completion of 12 Slingos, the Boost is replaced by the Jackpot symbol.
  • Jackpot Wheel: The Jackpot Wheel is perhaps the best bonus feature in the game, which is triggered at Full House. You can unlock multipliers from 750-2,500x the initial stake with this final wheel spin. The exclusive feature is offered only when 12 Slingos are completed.

Slingo Big Spin Booster is a fun and enjoyable mashup of bingo and slots, with a delightful circus theme, colourful graphics, and a clean and functional interface. The unique gameplay, featuring a 5x5 grid with a single spinning reel underneath, keeps you engaged as you mark off matching numbers.

Moreover, due to a stake range of £0.20 to £50, any player can choose to wager on the game, regardless of their budget.
