How To Play The Wild Booster Slot 

You can play this slot on any device ranging from mobile to desktop. Besides, the game can be relatively easy to play and navigate. Once you load it, you’ll discover that the interface is intuitive, with the control panel offering four buttons, including the coin stack, the three-line menu, the info button, and the spin icon.

  • Press the coin stack to open the betting options and see the available stakes. Then, you can set your preferred stake value using the + and – controls.
  • Tap the icon with three short horizontal lines to visit the menu where you can inspect the game settings and make any necessary changes. For example, you can customise the position of the spin button, or mute the game’s sound.
  • A small ‘i’ at the bottom of the screen represents the info button. You can click it if you need any information about the game, features, rules, and paytable.
  • Finally, hit the spin button to set the reels rolling in the Wild Booster slot!
  • Winning combinations can occur by landing three or more matching symbols, in left-to-right succession, across any of the fixed paylines.


Although the symbols in this slot are typical fruit symbols, they can be refreshing to see due to their exciting burst of colours. Asides from the usual fruits, you can also land the usual card suits, which add a regal look to the slot.

The following are the possible amounts you can get from each symbol if you land the highest combination of five across a payline.

  • Diamonds and clubs can award you up to 2.5x your stake;
  • Hearts and Spades can earn you at most 3x your wager;
  • Cherries can give you up to a 5x your bet payout;
  • Oranges are worth up to 7.5x your stake
  • Strawberries can fetch you as high as 10x your bet;
  • Lemons offer as much as 15x your wager; while
  • 7s can award up to a whopping 30x your stake for a five-of-a-kind combination!

Wild Symbols

Wild symbols can pop up on any reel during the game. They can also potentially assist you in completing a possible win, as they can replace all regular symbols except the scatter. They can also earn you a brilliant feature, as explained below.

The Wild Boost Win Multiplier Feature 

You can get this feature if at least one wild symbol appears on the reels after a spin. The feature can award you a multiplier with a random value ranging from x2 up to x100. However, the awarded multiplier can only apply to potential wins featuring at least one Wild.

Scatter Symbols

Diamonds are scatters and the only symbols that wilds cannot substitute. But, like the wild symbols, they can appear on any reel, and if three or more show up at once, you can get the Super Boost Free Spins feature. 

The Super Boost Free Spins Feature

Activating this feature via three, four, or five scatters can award you a go at the bonus game of your choice. In addition, you’ll get free spins and a progressive feature, no matter the game you decide to play. Below are the game options you can pick from and how they operate.

The Mega Boost Bonus Game

If you choose this game, you get an x2 multiplier that can apply to every combination involving a wild on the reels. The fantastic thing is that every five scatters that land during the round can upgrade your awarded multiplier. So, you may go from bagging a multiplier with an x2 value to one of x5, x10 up to a massive x100 win multiplier!

It doesn’t stop at that, though, as you can get an additional five free spins from every successful multiplier upgrade. However, scatter symbols may land less frequently here than in the other bonus game. Also, you will no longer be able to land free spins if you hit the maximum possible multiplier. 

The Ultra Boost Bonus Game 

This game plays out like its counterpart above. However, it comes with a few modifications. For example, the worth of multipliers you can get from the scatters collection in this round is higher. Also, this game has a higher probability of landing scatter symbols than the other. 

The milestones you can achieve each time you clock five scatter symbols in a spin during this round include x6, x12, or up to a x50 win multiplier.

Return To Player

Return to Player (RTP): 94.47%.

RTP is used to explain the potential money that an online slot or casino game can pay back to players. It appears as a percentage and is generally calculated from gameplay over a long duration of time.

For example, if a slot has a RTP of 97% this means that it could pay back £97 for every £100 wagered.

However, there is no guarantee that players will receive this amount, as slot payouts are entirely random.
