Wild Booster Slot Review

Enormous wild multipliers that can send payouts rocketing by up to 100x are central to the action in the Wild Booster slot, a classic fruit machine from Pragmatic Play. Played using a simple 5 reel, 20 payline game engine, look out for Wild Boosts which can randomly boost payouts by between 2 and 100x. Trigger the bonus and you’ll have the pick of 2 free spin features. They both come with expanding multipliers which increase each time you collect 5 scatters. Jump a level and you’ll also add more free spins to your total.  Find out more about this super volatile fruit machine in our full Wild Booster review.

Wild Booster Slot RTP, Details & Wager Limits

There’s a classic setup to the Wild Booster slot. This fruit machine reboot plays out on a 5 reel, 3 row, 20 payline machine. To create a winning combination, you’ll need to land 3, 4 or 5 matching symbols from left to right on 1 of those 20 paylines, starting from reel 1.

Stakes range from between 20p and £100 per spin. Click on the minus and plus buttons either side of the main spin button to change your stake accordingly. You can choose on the number of coins per payline as well as the coin value. There’s an Autoplay function available in some countries.

The Wild Booster RTP is 96.47% which is better than average but in line with other Pragmatic Play slot games. Tread carefully though as this slot delivers high variance action. The volatility is a maximum 5 out of 5. It offers a potential maximum win of 5,000 x your total stake.

Theme – Audio & Design Features – modern fruity reboot


The fruity theme in the Wild Booster slot is as old as it gets but there’s a fresh, modern look to the visuals here.  The glossy visuals are accompanied by a TV gameshow-style backing track which creates some atmosphere but isn’t annoyingly intrusive. It’s simple but the design here works well.

On the reels, you’ll see gemstone-style playing card suits alongside cherries, oranges, strawberries and lemons. The most lucrative standard symbol is the lucky red 7 which pays 2.5, 5 or 30 x your total stake if you land 3, 4 or 5 on a payline. There’s also a wild that can land on all 5 reels and substitute for all the standard symbols as well as a scatter.

Wild Booster is available to play on mobiles, tablets and desktops (laptops/PC). The slick imagery is super sharp, even if you’re using a device with a small screen. The simple but volatile gameplay is an ideal match for mobile play too. In the settings, there’s a Battery Saver mode which reduces animation speed (useful if playing on a mobile device).

Wild Booster Bonus Features

When it comes to features in Wild Booster, free spins and wild multipliers are the name of the game. The wilds can send payout soaring in both the base game and the feature round where you’ll have the pick of a pair of free spin bonuses.

Wild Boost feature

The Wild Boost feature can trigger on any spin that includes a wild. If triggered, you’ll then receive a random multiplier that starts at 2x but can get as high as 100x. Any wins that include a wild are boosted by the multiplier.

Super Boost Free Spins features


Landing 3 or more diamond scatter symbols on the same spin trigger the Super Boost Free Spins features. You’ll then have a choice of 2 free spins games:

Mega Boost Free Spins feature: you’ll start this round with 5 free spins and a 2x multiplier active. Above the reels, you’ll see a multiplier trail. The triggering scatters are added to the trail. Each scatter that lands also joins the trail. When you have collected 5 scatters, the value of the multiplier increases to 5x and 5 more free spins are added to your total.

Collect another 5 scatters and the multiplier rises to 10x and 5 more spins are added. If you manage to collect another 5 scatters, the multiplier rises to a massive 100x with 5 more free spins added to your tally. There are fewer scatters on the reels during this round that usual so it’s harder to increase the multiplier. The potential rewards are big on the rare occasions you do so though. This is the high variance pick.

Ultra Boost Free Spins feature: once again 5 free spins are awarded, this time with a starting multiplier of 3x. Collecting scatters in this feature takes the multipliers up to 6x, 12x and potentially 50x, complete with blocks of 5 extra free spins.

You’ll see more scatter symbols than in the Mega Boost Free Spins meaning you’re likelier to get a retrigger and a multiplier boost. Those multipliers aren’t as big as in the Mega Boost. This is the lower variance option of the 2 but it’s still pretty fiery.

In some countries, there’s an option to buy the free spins for a fee of 75 x your total stake. The number of scatters that land is randomly chosen and can be 3, 4 or 5. This could have an impact on which of the free spin features you’ll choose. Unfortunately, this option isn’t available in the UK.

Wild Booster Review Summary – simple, high variance fruit machine inspired action

The humble fruit machine remains a popular theme for players, especially when they come with some funky features to rev up the gameplay. That’s precisely what Pragmatic Play has done with the Wild Booster slot. The wild extras can really get things moving in the free spin features.

I would opt for the Mega Boost Free Spins feature as the potential 100x multiplier can prove more fruitful. The key to winning big is to land a couple of retriggers so the wild multipliers increase. Highly volatile, the only downside of Wild Booster is the max 5,000 x stake win.

If you want the choice of free spins features with wild multipliers, the Wild Flower slot by Big Time Gaming would be my pick. 1 of the features has a Multiplier Ladder than can give you multipliers up to 800x. Another option is Quickspin’s Guardian of Athens which gives you 4 options in the free spins. These can create multipliers up to 1,680x.
