9 Pearls of Fortune Slot Review
iSoftBet have carved out a distinct presence in the underwater slots niche, and 9 Pearls of Fortune continues that trajectory with a tranquil ocean setting. Released in February 2023, this mid-low volatility title presents a fundamentally different proposition from the studio’s higher-intensity offerings. The game’s appeal centres on soothing aesthetics and accessible mechanics rather than explosive win potential, positioning it squarely for casual players who prioritise session longevity over high-variance chases.
Base Game & Features
The game operates on a 5×3 grid with 20 paylines, delivering a classic reel structure familiar to most slot players. Visual presentation stands out as a genuine strength, featuring soft pastel colours and cartoon-style aquatic creatures across the reels. A gentle bubbling soundtrack complements the aesthetic, creating an exceptionally relaxing atmosphere. With an RTP of 96.00%, the game sits exactly in line with industry averages, representing solid value for players.
The mid-low volatility profile means wins arrive with reasonable frequency, though individual payouts remain modest. This balance enables longer play sessions without dramatic bankroll fluctuations—an ideal configuration for those seeking to unwind rather than chase astronomical multipliers. Base game pacing is deliberately calm, designed for relaxation rather than adrenaline.
Bubbly Modifier
A random base game feature that can trigger unpredictably during standard spins. When activated, bubbles fill the reels with the potential to award either Pearl Respins or the Free Spins Bonus directly. The modifier adds welcome variety to base gameplay, though activation frequency remains inconsistent. When it does trigger, it bypasses the standard scatter requirements for accessing bonus features.
Pearl Respins
The Pearl Respins feature triggers when you land 3 or more pearl symbols on reels 2, 3, and 4. Triggering pearls become sticky, and you receive 1 respin that re-triggers for each additional pearl collected. The escalating reward structure operates as follows:
- 3 sticky pearls: 1x stake
- 4 sticky pearls: 3x stake
- 5 sticky pearls: 5x stake
- 6 sticky pearls: 10x stake
- 7 sticky pearls: 25x stake
- 8 sticky pearls: 50x stake
- 9 sticky pearls: 100x stake
The mechanic can be engaging, particularly when additional pearls land during respins and the payout climbs progressively. However, the 100x maximum from Pearl Respins feels relatively restrained compared to similar mechanics in other slots. The feature delivers entertainment value through its respin tension, though players chasing significant multipliers should adjust expectations accordingly.

9 Pearls of Fortune Free Spins
The Free Spins Bonus triggers when you land 3 Treasure Chest Scatter symbols on reels 1, 3, and 5. A bonus wheel then spins to award one of three prize combinations:
- 10 free spins with a 2x multiplier
- 12 free spins with a 3x multiplier
- 15 free spins with a 5x multiplier
The multiplier applies to all wins during the feature, providing meaningful uplifts to standard payouts. The bonus wheel adds an element of anticipation, though which outcome you receive is entirely random. Pearl Respins can also trigger during free spins, with the multiplier applied to the respin payouts—this interaction creates the pathway to the game’s 750x maximum win.
The feature delivers straightforward, accessible gameplay without excessive complexity. The multiplier tiers offer reasonable variation, though the overall win ceiling remains firmly capped. For players familiar with modern high-volatility slots regularly offering 5,000x+ potential, the 750x limit will feel underwhelming.

Bonus Buy
Note for UK Players: The Bonus Buy feature is not available for players in UK jurisdictions due to UKGC regulatory restrictions.
For players in eligible jurisdictions, the Bonus Buy feature allows direct purchase of the Free Spins Bonus for 50x the stake. This cost is relatively affordable by modern standards, providing immediate access to the bonus wheel. When using Bonus Buy, the game’s RTP increases from 96.00% to 96.59%, representing a modest but genuine improvement in theoretical return.
However, some professional reviews note that Bonus Buy sessions can deliver disappointing results, with actual payouts occasionally underperforming player expectations relative to the 50x cost. This is particularly relevant given the 750x maximum win cap—even optimal bonus rounds remain restrained compared to other slots offering bonus purchase options.
Our Honest Verdict
Rating: 6.0/10
9 Pearls of Fortune is a well-crafted mid-tier offering that excels in visual presentation, relaxed pacing, and smooth mechanical execution. The tranquil ocean theme is beautifully realised through excellent graphics, soft pastel colours, and a soothing soundtrack that genuinely creates a calm playing environment. Feature diversity is solid—the combination of Pearl Respins and Free Spins Bonus with multiplier tiers provides enough variety to maintain interest across extended sessions.
The game sits comfortably in its low-to-medium volatility space, delivering the session longevity and bankroll stability that casual players prioritise. With a 96.00% RTP matching industry averages and a straightforward 5×3, 20-payline structure, the mechanical foundation is entirely competent. The Bubbly Modifier adds welcome unpredictability to base game spins, and the escalating Pearl Respins payout structure creates genuine tension as additional pearls land.
However, the 750x maximum win is genuinely underwhelming by modern slot standards. For context, many comparable mid-volatility titles now offer 2,000x-5,000x potential, making 9 Pearls of Fortune’s ceiling feel severely restrained. The Pearl Respins top payout of 100x, whilst mechanically sound, lacks the explosive potential found in similar collect-and-hold features from competitors. This isn’t a game for high-variance chasers or players seeking transformative wins—it’s built for a fundamentally different experience.
The game is particularly well-suited to casual punters who prefer lower volatility and longer play sessions without significant bankroll fluctuations. It genuinely excels as a slot for unwinding after a long day, delivering visual calm and accessible gameplay. However, it cannot be considered one of iSoftBet’s heavyweight slots—there are several titles in their portfolio that outperform 9 Pearls of Fortune in both appeal and win potential.
Community player ratings stand at approximately 2.9 out of 5 stars across aggregated reviews, indicating mixed reception. Whilst the game delivers on its promise of relaxed, visually appealing gameplay, actual payout experiences appear to disappoint some players relative to the mechanics’ perceived potential. Professional reviewers consistently note its competent execution but unremarkable positioning within the crowded underwater slots market.
For players seeking higher win potential, consider exploring alternatives offering greater maximum multipliers. 9 Pearls of Fortune will more than suffice for those valuing aesthetic quality and calm session pacing, but thrill-seekers should look elsewhere in iSoftBet’s catalogue.
