Big Bass Bonanza: Fishing Adventure with Multipliers
Gameplay Appeal
Pragmatic Play’s Big Bass Bonanza is all about the free spins round. Landing three or more scatter symbols unlocks spins where the fisherman wild symbol collects fish icons carrying cash values. Each retrigger not only adds more spins but also increases the multiplier, climbing from 2x to 10x.
For UK players, spins begin from £0.10 on licensed sites, making it budget-friendly. However, because it’s a high-volatility slot, you may encounter stretches of quiet spins before bonuses land. This unpredictability is part of its design, and like all slots,the results are completely luck-based.
Who It Suits
Big Bass Bonanza suits players who enjoy the excitement of chasing bonus rounds, don’t mind waiting for them, and prefer light-hearted fishing theme slots over darker or more intense visuals.
Starburst: Cosmic Classic for Steady Play
Gameplay Appeal
NetEnt’s Starburst has been a top slot in the UK for over a decade. Its popularity comes from its simplicity. With 10 paylines and bold, colourful graphics, the highlight feature is the expanding wild re-spin. When a wild gem lands, it fills the reel and triggers a re-spin. Land multiple wilds in sequence, and the screen lights up with colour.
Unlike Big Bass Bonanza, wins here are typically smaller but more frequent thanks to its low-to-medium volatility.
Who It Suits
Starburst is perfect for beginners or anyone who enjoys steady pacing without long waits for bonuses. It’s proof that a straightforward slot can remain timeless.
Rainbow Riches: Irish Charm and Bonus Variety
Gameplay Appeal
Rainbow Riches is one of the UK’s most recognisable slot names. Its enduring popularity comes from its quirky bonus rounds, including Road to Riches, Wishing Well, and Pots of Gold. Each feature is triggered by landing scatter symbols, keeping gameplay varied and playful.
While its RTP of 95% is lower than some modern titles, the character-filled Irish theme and nostalgic link to UK arcade slots have kept it beloved for years.
Who It Suits
Rainbow Riches is ideal for players who want variety in their bonus rounds, don’t mind medium volatility, and enjoy a nostalgic, light-hearted design.
Book of Dead: High-Variance Egyptian Adventure
Gameplay Appeal
Book of Dead by Play’n GO is a high-volatility slot centred around its free spins feature. When triggered, one random symbol expands during the bonus, creating the potential for full-screen wins. The theme is cinematic, with Egyptian temples and heroic adventuring.
Although its RTP of 96.21% is competitive, the high variance means players may face long stretches of smaller or no wins between bonuses. It’s designed for those who like risk and unpredictability, though every outcome still comes down to chance.
Who It Suits
Book of Dead is best for players who enjoy adventurous themes, don’t mind swings in volatility, and are comfortable with a slot that can be feast-or-famine in style.
Comparing Features Across the Board
RTP Observations
- Highest RTP: Big Bass Bonanza at 96.71% gives it a slight statistical edge.

- Low volatility: Starburst, for more frequent but smaller wins.
Feature Variety
- Big Bass Bonanza focuses on retriggers and multipliers.

Luck, Not Strategy: A Reminder
It’s important to stress that while features and volatility shape the feel of a slot, they don’t change the fact that all outcomes are random. Whether you choose Big Bass Bonanza, Starburst, Rainbow Riches, or Book of Dead, each spin is down to luck.
Managing Expectations
- Big Bass Bonanza can go long stretches without a bonus.
- Starburst may give frequent small payouts.
- Rainbow Riches offers unpredictable side games.
