Big Wolf Bonus Booster Review

Big Wolf Bonus Booster is an online slot released in March by the industry-renowned game developer Inspired Gaming. It is a game designed in a rather retro style with plenty of wolves and other animals on the reels. The slot features a payline mechanic and is packed with all the technical tools that the provider is famous about!

Inspired Gaming is among the most trusted and reputable slot developers on the market. That has been the case since its establishment, and the company continues to operate in both fields - iGaming and VLT machines. Big Wolf Bonus Booster is the 3rd installment of a series started by Inspired half a decade ago - Big Bonus.

Three years later, a sequel was presented - Big Bonus Booster, and here we are with the most recent addition to the franchise. Despite the animal vibe and theme here, the slot remains almost fully based on classic gambling. Mechanics are also from the dawn of online slots, although the grid is wider than usual - 6x4 and lines are 50!

However, they still pay from the leftmost reel to the right and require at least 3 of a kind aligned. The good news is that, similar to the previous 2 titles, all symbols tend to land in stacks. Except the scatters, of course, as they have a more paramount role! There are sticky wilds, free spins, a Pick Me minigame, and many other useful features that will keep you engaged all the time!

Big Wolf Bonus Booster is loaded with tempting cash rewards that can drop in if you line up 3 or more symbols of the same type. Wolves pay from 0.50x to 20x, Eagles award from 0.50x to 15x, while Bears, and Cougars pay between 0.40x and 10x. The low-valued symbols A, K, Q, J, 10, and 9 bring lower payouts in the range from 0.10x to 8x the bet.

Wolf howling on a full moon is the wild symbol in the game, and it substitutes for the others, except scatters. Moreover, wilds pay the sweetest rewards if lined up, from 1x to 250x the stake! The slot comes with a pretty wide betting range that will cater to most gamblers out there - €0.10 up to €200 per spin.

The Big Wolf Bonus Booster RTP ranges and remains below the usual average of 96%. As it often happens in recent years, Inspired Gaming has kept this indicator low - 94.50% and 92%. The game's volatility remains uncertain, but in my opinion, it is about medium. The Big Wolf Bonus Booster max win is €250,000 or up to 1,250x the bet.

Big Wolf Bonus Booster Features

Big Wolf Bonus Booster offers some of the popular features crafted by the provider. Slot enthusiasts have tried them before and will not find anything new or expanded here. The slot feels like a reskin of Big Bonus Booster with animals instead of gems and fruits on the reels. Still, these features can be quite generous, and here are the details:

Big Bonus Entry & Match 3 Pick Me

Bonus symbols are scatters and may land on all reels to activate the Big Bonus round. You will need at least 3 of them at the same time, and their number will determine the Big Bonus starting value as displayed below:

  • 3 Bonus Scatters - 20x, 25x, 30x, 50x, or 100x the bet
  • 4 Bonus Scatters - 25x, 30x, 50x, or 100x the bet
  • 5 Bonus Scatters - 30x, 50x, or 100x the bet
  • 6 Bonus Scatters - 50x or 100x the bet

Big Bonus Match 3 Pick Me is the second stage of the pre-bonus minigame, and it will start with 6, 9, 12, or 15 tiles face-down. The number depends on the possible values determined by the scatters. Tiles reveal the Big Bonus Wolf in various colors, which will be collected by the respective pots. When you fill one with 3 of a kind, the Bonus Game will begin.

Free Spins Bonus

Free Spin is unlimited and will end when you manage to score a win equal to or bigger than the active Big Bonus Multiplier in a single spin. All smaller wins before that will be piled up and will also be awarded. Bonus Game has a Level Up mechanic, and Big Bonus Wolves may land on reel 6.

They will be added in the empty spots to potentially upgrade the Multiplier on the Boost Trail. Furthermore, all wild symbols that land during the free spins sequence will become sticky and will be held in their positions. Thus, with every spin, the odds of hitting a big win increase exponentially.

Fortune Bet

Fortune Bet plays the role of a bet booster in the Big Wolf Bonus Booster slot. You can enable it through the toggle on the left, and this will increase your bet by 50%. Fortune Bet will not increase the line wins or on any other cash values in the game, but will double the chance of activating Big Bonus Free Spins.

Gamble

Gamble Game is standard for Inspired Gaming, designed to awaken the players’ nostalgia for the old times. The tab in the upper right corner has 3 positions - On, Off, and 5x. I’m confident that the first and second ones require no presentation, while the 3rd option activates the Risk game after wins of 5x the bet or higher. Bonus Wheel in the form of a pie will appear, and you must spin it to win or lose.

Spin Chance

Spin Chance is another feature typical for the provider, and this one is fully automated. It activates if your balance drops below the bet size but is still higher than zero. You’ll be presented with a chance to gamble the remaining money for one more spin at the selected stake level. Green - you win, red - you lose!

Theme & Graphics

Big Wolf Bonus Booster comes with crisp graphics, but nothing too exceptional, bringing time back to the days when animal slots were hot. The Wolf theme is one of the most exploited ones, along with ancient civilizations and sweets. Here, we have a huge grid taking most of the space of your screen, in case you have run it in landscape mode.

It is an HTML5 slot, so you can play it easily on desktop and mobile devices. The soundtrack is melancholic, and the provider has not missed the usual generic audio effects when the reels stop. Overall, the game stands and feels well, which is somehow expected by a provider with the experience and resources of Inspired.

Pros And Cons Of Big Wolf Bonus Booster Slot

Pros

  • 50 paylines to win cash rewards
  • Stacked symbols including wilds on all reels
  • Fortune Bet to increase your bonus triggering chances
  • Big Bonus with 3 Pick Me pre-game
  • Free Spins with an upgradable minimum win
  • Wilds are sticky during the unlimited free spins
  • Gamble Game and Spin Chance
  • Win up to €250,000

Cons

  • RTP rate ranges and is below the average
  • Reskin of the Big Bonus Booster slot

Our Verdict

Big Wolf Bonus Booster offers what I was expecting - a nice overall performance with 50 lines on a wide grid. The variety of technical features is high, and the single bonus is well-designed. Seasoned gamblers will surely enjoy the pre-bonus and the part with the Wolf picking tiles. Moreover, the non-winning ones are not lost!

In fact, that is what makes the Inspired Gaming slots so sophisticated - the attention to detail. Tiles with Wolves that have been revealed but are not the type that trigger the bonus will be saved in the respective Boost Trail tiers. This way, the respective level-up sequence for the multiplier will be shorter!

It’s all great and exciting, if it wasn't for the fact that we have seen it already, not long ago. I can’t really find any differences between Big Bonus Booster and Big Wolf Bonus Booster, except for the theme and visual effects. Most features are identical in Big Bonus from 2020, too, but at least the RTP rate is higher.

So, if you like the concept and have been spinning the reels of the previous two games from the series, this one is a must. It is well-crafted and spins fast, creating a feeling of the past but in a brand-new wrap. The wide betting range will help you build a strategy and perhaps beat the House edge created by the low RTP!
