Slingo Big Spin Booster Game Features

This circus-themed Slingo game comes with an interesting Bonus Wheel system to keep the show exciting. Each game starts with 10 spins on the bottom reel and you’ll aim to cross out as many numbers as possible, with each one lighting up the next position on the Payladder above the reels. Here are the rewards that you can unlock as you land Slingos:

Four Slingos allows you to claim a Cash or Wheel Boost.
From five Slingos up, you can claim Cash, Wheel Boost, or Quack Shot Bonus
A full house of Slingos means you can claim Cash, Quack Shot Bonus, Boom Brothers Bonus or the Jackpot Bonus Wheel.

Slingo Big Spin Booster Cash Awards Feature

If you land four to 12 Slingos, you can win 1x to 250x your wager.

Slingo Big Spin Booster Quack Shot Bonus Feature

The Quack Shot Bonus becomes available at five Slingos, where you’ll pick a duck to reveal a cash prize between 2x and 25x the bet. Higher variations available with more Slingos can push the prize up to 250x the bet.

Slingo Big Spin Booster Boom Brothers Bonus Feature

The Boom Brothers Bonus becomes available at six Slingos, where you’ll pick a cannon to reveal a prize between 6x and 100x the bet. Higher Payladder variations can take the prize up to 2,250x the bet.

Slingo Big Spin Booster Boost Feature

A Boost increases the value of all Cash rewards and bonuses by one Slingo level, after which you’ll then receive one extra spin. If you’re lucky and land a full house, the Boost icon will transform into the Jackpot icon.

Slingo Big Spin Booster Jackpot Wheel Feature

Once you’ve completed a full house on the Slingo grid, the Boost segments on the Bonus Wheel turn into jackpot segments. Landing one of these segments on the Bonus Wheel spin will get you an extra spin on the Jackpot Wheel with four different prize tiers.

Slingo Big Spin Booster Game Bonuses and Jackpots

This Slingo game does Jackpots a little differently from regular slots. There’s only one way to access the jackpot wheel, and you’ll need to complete a full house to get there. The Jackpot Wheel is awarded by chance if you hit the right segment on the bonus wheel, but if you do, you get access to one of four jackpots, valued at 750x, 1,000x, 1,500x, and 2,500x the bet. The good news is that even if you don’t land a jackpot segment on the full house Bonus Wheel, the other feature combinations can still get you a chance at the game’s 6,050x top prize

How To Win the Slingo Big Spin Booster Game

There’s no specific strategy for playing Slingo games online, as each has its own unique twist. But there are a few basics to keep in mind. Generally, you’ll complete Slingos by marking off numbers on the main grid as they match those spinning up on the bottom reel.

As you complete more horizontal, vertical, and diagonal lines, you’ll increase the prizes you can claim. You can complete more than one Slingo with a single number once your grid starts to fill up. And once you reach a certain number of Slingos you can start claiming tiered prizes.
