Bomb Bonanza Casino Game
Bomb Bonanza features a lively mining town setting with cheerful graphics. Symbols include gold nuggets, pickaxes, dynamite, and miners, bringing a classic gold rush theme to life. The atmosphere is bright and approachable, with colourful animations and playful sound effects that add charm to each spin.
What Are the Main Features and Special Symbols in Bomb Bonanza?
Bomb Bonanza includes dynamic features centred around Wild symbols and the Free Spins bonus round. The Wild symbol substitutes for all other symbols except the Free Spin symbol, increasing the chances of forming winning combinations. Wilds can appear on any of the five reels. The Free Spin symbol, which is found exclusively on reels 1, 3, and 5, is the key to unlocking the Free Spins feature when three appear on the reels simultaneously.
How Do Expanding Wilds Work?
Each time at least one Wild symbol lands on the reels, all Wilds present may randomly expand in a square formation, anywhere from 1x1 to 5x5 in size. This expansion replaces adjacent symbols with additional Wilds, further boosting win potential whenever the feature is triggered.
How Is the Free Spins Feature Triggered and Played?
To trigger the Free Spins feature, land three Free Spin symbols during a single spin. This activates six free spins to begin with. During the Free Spins round, special Gold Nugget symbols may land. Each Gold Nugget is collected in a meter and explodes upon collection, causing surrounding symbols to drop away and be replaced by new ones from above, creating fresh chances for winning combinations.
The Free Spins round is progressive, offering additional rewards as you collect more Gold Nuggets:
- The round starts at Level 1, where Wilds expand in a 1x1 pattern.
- Gather 5 Gold Nuggets to reach Level 2, unlocking 4 extra free spins and Wilds that expand in a 2x2 pattern.
- Collect another 5 Gold Nuggets for Level 3 to receive 2 more spins and 3x3 expanding Wilds.
- Five more Gold Nuggets advance you to Level 4, awarding 2 further free spins and 4x4 Wild expansions.
- Collect 3 Gold Nuggets for Level 5, which gives 1 additional free spin and expands Wilds in a 5x5 formation.
If multiple levels are reached within the same spin, only the free spins from the highest level attained are added. Special reels are used during the Free Spins feature to enhance gameplay.
How Are the Game Mechanics Structured?
Bomb Bonanza, developed by Pragmatic Play, is designed with 5 reels and 50 paylines. All symbol wins are awarded for adjacent combinations running from left to right, starting on the leftmost reel. Only the highest win is paid for each line, but wins on different paylines are added together to form the total win for each spin.
- Wins are calculated by multiplying the prize by the bet per line.
- The total win from Free Spins is added to the payline wins.
What Is the Minimum and Maximum Bet?
The minimum bet per spin is £0.25 and the maximum bet is £5.00.
What About Volatility and Payouts?
Bomb Bonanza is a high volatility slot. This means that while wins may not occur frequently, they can be more substantial when they do happen. The RTP value can be viewed within the game itself. The maximum possible win per single game round is 1,665 times your bet. If this limit is reached, the round concludes immediately and any active features end at that point.
Are There Any Additional Rules Players Should Know?
- All reels are subject to malfunction voiding all plays and pays.
