Author:
Last updated: Big Thunder is an engaging online slot developed by Ainsworth.
It is known for its vibrant theme and exciting features. Launched in the early 2010s, this video slot offers players a captivating experience with unique visuals and sounds. It's commonly found in online casinos.
The game is known for its Wild Gorilla symbol and Thunder scatter, which provide an interesting gaming experience for both new players and seasoned gamblers.
This Big Thunder online slot review will explore the game's mechanics, symbols, bonus features, and more, comprehensively examining its offerings.
Reels, Rows and Paylines
Big Thunder is a video slot game featuring a classic layout with five reels and three rows.
This arrangement is typical in slot games, providing a familiar setup for players. The game offers 30 adjustable paylines, allowing players to choose how many lines they wish to activate per spin.
This flexibility allows for various playing styles, from those who prefer to play conservatively with fewer paylines to those who like to maximise their chances by activating all 30. The paylines run from left to right, and players can form winning combinations by landing matching symbols on these lines.
The ability to adjust paylines adds a strategic element to the game, letting players control their risk and reward levels. This setup, combined with the game's engaging theme and features, makes Big Thunder an appealing choice for new and experienced slot enthusiasts.
Symbols
Big Thunder features a variety of symbols that enhance its jungle theme.
The game includes standard playing card symbols (9, 10, J, Q, K, A) that serve as the lower-paying icons. The higher-paying symbols work off the Big Thunder theme, including tribal drums, masks, shields, snakes, and waterfalls, each contributing to the game's adventurous feel.
The iconic silverback gorilla represents the wild symbol, which can substitute for all other symbols except the scatter to help form winning combinations. Landing multiple wilds can lead to significant payouts, with the potential to win up to 200 times the line bet when five wilds appear on a payline.
This mix of symbols adds visual appeal and offers players various opportunities to achieve winning combinations and enhance their gaming experience.
Scatters and Bonus Features
Big Thunder includes exciting bonus features that are triggered by scatter symbols. A lightning bolt represents the scatter symbol, and landing three or more symbols anywhere on the reels activates the free spins feature.
Players are awarded 15 free spins, during which additional scatter symbols can retrigger more free spins, extending the bonus round. The game also features a special 6th reel that can appear during the bonus round, offering the chance to win one of four jackpots.
The major bonus can reach 10,000 times the line bet, providing substantial winning potential. To win a 10,000x line bet prize, find five masks, drums, snakes, a waterfall, or shield icons. These bonus features during the free games can significantly boost a player's winnings.
RTP and Volatility
The Return to Player (RTP) percentage for Big Thunder is approximately 94.39%, slightly below the industry average for online slots. This RTP indicates that, on average, players can expect to receive back 94.39% of their total bets over a long period of play.
The game is classified as a high volatility slot, meaning that while wins may not occur frequently, they tend to be more significant when they do hit. This volatility level appeals to players who enjoy the thrill of chasing big wins, as the potential payouts can be worth it.
This also means that players should be prepared for periods of play without significant wins, making it important to manage their bankroll.
Stake Limits
Big Thunder offers a range of stake limits to accommodate different types of players. The minimum bet per spin is 1.25 credits, making it accessible for casual players or those who prefer to play with smaller stakes.
The maximum bet for the Big Thunder slot game can go up to 3,000 credits per spin when the maximum number of paylines are activated. It's great news for high rollers who enjoy placing larger bets for the chance of bigger wins.
Of course, punters can also adjust the coin value to suit their preferred betting level.
Big Thunder also includes an autospin feature, allowing players to set a predetermined number of spins to play automatically. However, it does not offer a loss limit setting, so players should monitor their balance and play responsibly.
Visuals and Audio
Big Thunder's jungle theme design contains vibrant 2D graphics that display the lush rainforest jungle and its inhabitants. The symbols and background are well-crafted, creating an atmosphere that draws players in.
The game's audio complements the theme with sounds that improve the overall experience. However, it does lean towards a more traditional slot machine sound rather than incorporating specific jungle or animal noises.
The combination of visuals and audio creates an inviting backdrop that keeps players entertained throughout their gaming session. While the graphics are not the most modern, they effectively capture the spirit of the jungle theme.
Mobile vs. Desktop
Big Thunder slot machine functions equally well on mobile and desktop platforms, offering faultless gameplay experiences across devices. It is not restricted to working only on mobile; players can also access it via desktop computers.
The game is compatible with Android and iOS operating systems, allowing users to enjoy it on smartphones and tablets. Whether mobile or desktop, Big Thunder maintains high-quality graphics and smooth gameplay. Therefore, all features, such as wild symbols, scatter symbols, free spins, and jackpot opportunities, are fully accessible.
