Net Gains Slot Review

Relax Gaming have built a strong track record with the Swole series, and Net Gains represents the third collaboration with Casino Grounds. Released in December 2022, this high-volatility offering stands apart from its predecessors through expanded feature variety and refined game design that eliminates some of the more punishing mechanics found in earlier entries. The ocean-themed setting with muscular animal symbols creates a distinctive visual identity, though the real appeal lies in the layered feature system and strategic options like the Special Bet mechanic that shift how players can approach gameplay.
Base Game & Features
Net Gains operates on a 6-reel, 4-row grid with 4,096 ways to win, powered by cascading reels that remove winning symbols and allow new ones to cascade from above. This mechanic enables multiple consecutive wins from a single spin and fundamentally drives the game’s volatility profile. The cascading system creates natural win streaks when conditions align, though it also means dead spins can occur during bonus rounds when combinations don’t form.
Mystery Symbols
The game features three distinct mystery symbol types that enhance base game play significantly. Regular mystery symbols reveal identical symbols once they land, Standard octopus mysteries change symbols into matching mystery symbols for potential multi-symbol coverage, and bomb mysteries destroy all non-mystery symbols after wins occur. This layered approach to mystery mechanics gives players visual excitement and creates situations where base game wins can feel substantial, particularly when multiple mystery types interact during cascades.

Bonus Features & Free Spins
Landing three bonus symbols triggers the free spins selection screen, where players choose from three distinct modes. Each provides different risk-reward dynamics, making the choice meaningful based on player preference and current session conditions. All free spins modes benefit from the cascading mechanic, with potential for extended play through symbol retriggering.

Sticky Mystery Free Spins
Sticky Mystery awards 5 free spins with sticky mystery symbols that appear on reels 2 through 6, remaining locked in position throughout the round. This mode provides focused win potential through accumulated mystery symbols, creating situations where the round can develop significant momentum as more symbols stick into position. Community feedback identifies this as a favourite among players for delivering engaging, sustained play.

Stacked Wilds Free Spins
Stacked Wilds provides 7 free spins with multiplier wilds ranging from 2x to 5x and countdown wilds that reset after triggering. This mode emphasises win multipliers, making large cascades particularly rewarding when multipliers combine with winning symbol clusters. The countdown wild mechanic extends playability by resetting after each use, potentially allowing multiple multiplier activations during a single round.

Coin Collection Free Spins
Coin Collection grants 8 free spins centred on an upgradeable coin mechanic. Players collect gold, silver, and bronze coins during the round, with the ability to upgrade coin values and retrigger spins when sufficient coins accumulate. This mode involves the most player engagement through the meta-game aspect, though it also carries the highest complexity and longest potential playtime of the three options.

Special Bet & Lucky Boost
The Special Bet feature increases stake by 20% whilst boosting free spins trigger probability by 82%, creating a compelling value proposition. For players seeking more frequent bonus access, this represents genuine mathematical advantage—paying 20% more for an 82% increase in trigger likelihood. The RTP increases to 96.50% when Special Bet is active, rewarding the increased cost commitment.
Lucky Boost activates randomly at the start of free spins rounds, temporarily increasing win odds and creating potential for outsized early-round cascades. This feature adds an element of pleasant surprise to bonus rounds, though it occurs infrequently enough that players shouldn’t expect it as a standard bonus element.
Bonus Buy
Outside the UK, players can purchase free spins directly for 100x their current bet, selecting their preferred mode in advance. The RTP increases to 96.50% for bonus buy spins, mirroring the Special Bet mechanic. This feature provides players seeking immediate feature access a direct path to bonus play, though the cost means it suits session-extension play more than base-game damage recovery.
Our Honest Verdict
- Overall Verdict: 7.5/10 — Net Gains represents a refined third entry in the Swole series that prioritises feature variety and player agency over raw max win potential.
Net Gains achieves something genuinely interesting within the high-volatility landscape: it gives players meaningful choices through multiple free spins modes and the Special Bet mechanic. The 96.10% base RTP, escalating to 96.50% with features, sits competitive within the market. The 6×4 cascading grid with 4,096 ways creates natural win potential that extends beyond feature play, though the high volatility (5/5 rating) means base game sessions can feel sparse for players accustomed to medium-volatility pacing.
The 15,000x maximum win is theoretically achievable but rarely observed in practice—real player data shows the highest recorded win around 836x, representing a significant gap from advertised potential. This positioning is typical for high-volatility slots and shouldn’t surprise experienced players, though it warrants transparency. Hit frequency of 27.03% delivers approximately one winning combination every 3.69 spins on average, supporting steady base game engagement despite the volatility classification.
Compared to earlier Swole series entries, Net Gains delivers more mystery symbol variety than Beast Mode or Iron Bank, having eliminated Beast Mode’s brutal gamble feature entirely. The 15,000x cap sits below Beast Mode’s 25,000x and Iron Bank’s 49,998x, but the refined feature execution and player-friendly design choices offset the statistical regression. The game positions itself squarely for high-volatility chasers seeking substantial multi-spin sessions with feature-rich gameplay rather than players hunting maximum theoretical payouts.

How does the cascading reels mechanic work?
When winning symbols land, they’re removed from the reels and new symbols cascade down from above, filling the empty spaces. This can create multiple consecutive wins from a single spin. The mechanic drives the game’s volatility profile and creates potential for extended win streaks when conditions align, though it also contributes to dead spin potential during bonus rounds.
