Scarab Boost

Scarab Boost Slot Review — 3 Oaks Gaming

Scarab Boost is a video slot from 3 Oaks Gaming, released on June 10, 2021, built on a 5-reel, 25-payline layout with a Hold and Win core mechanic set inside an Ancient Egyptian scene. 3 Oaks Gaming is headquartered in Douglas, Isle of Man, and operates under licences including the Isle of Man Gambling Supervision Commission, UK Gambling Commission (UKGC) and Malta Gaming Authority (MGA), alongside additional certifications covering markets such as the UK, Italy, Bulgaria and Georgia — a studio background worth knowing before judging any single title from its catalogue.

Core Gameplay Experience

Scarab Boost runs on a 5-reel grid with 25 fixed paylines, and stakes span from 0.25 to 60.0 per spin, giving a wide enough range for both cautious testing and larger bets once the mechanics are understood. The pacing follows the standard reel-spin rhythm of this format: base-game spins alternate with a Hold and Win style respin trigger rather than constant animation-heavy sequences.

The visual theme leans on Ancient Egypt — a pharaoh and Cleopatra motif rendered in a palette of dark blue and purple against gold symbol accents — a setting shared by many titles under the Ancient & Historical slot category. The theme itself does not change the math, but it frames the symbol set players will recognise from scarabs, hieroglyphs and royal iconography throughout the reels.

Features and Mechanics

The feature set combines Wilds and Stacked Wilds with Stacked Symbols to build larger single-spin combinations, while Scatter Symbols and Free Spins provide the standard route into an extended bonus sequence. The Hold and Win / Hold and Spin round is the centrepiece: qualifying symbols lock in place and trigger a respin sequence, with a Cash Collector symbol adding accumulated value on top of whatever the locked positions pay out. A Multiplier can apply on top of these results, and Bonus Symbols feed into a separate Bonus Game trigger, a mechanic family covered more broadly on the Bonus Game slots page. A Jackpot element is also listed among the game’s features, though the payout structure behind it is not published in the game’s technical documentation, so it should be treated as a possibility rather than a guaranteed route to a fixed prize.

RTP, Volatility and Payout Model

Scarab Boost pays out at a theoretical 95.77% RTP with a high volatility profile, meaning the game is built to produce fewer winning spins in exchange for the chance at larger payouts, up to a stated 5,000x stake ceiling. That 95.77% figure sits in the 39th percentile of the 4,445 slots in our catalog with a published RTP, where the catalog median is 96% and the bottom quartile sits at 95.21% or lower — so Scarab Boost lands in the lower-middle band of RTP figures we track, not an outlier in either direction. High volatility is shared by 63% of the 4,737 slots in our catalog (2,962 titles), so the risk profile itself is a common one rather than unusual; what varies between titles is how that risk is delivered, and here it runs through the Hold and Win respin round rather than through the base game.

Similar 3 Oaks Gaming Slots — Comparison

Among these four 3 Oaks Gaming titles, Wolf Saga offers the only medium-volatility option and the highest RTP of this group, while Tiger’s Gold Hold and Win sits at the low end on RTP with the same high-risk profile as Scarab Boost. Players who want the Hold and Win format with a gentler swing pattern may prefer Wolf Saga; those comfortable with longer dry spells will find Scarab Boost and Wolf Night closer in character.

Similar Hold and Win Slots from Other Studios

Every slot in this table shares a high volatility rating with Scarab Boost, but each carries a higher RTP than Scarab Boost’s 95.77%, with Rich of the Mermaid topping the group at 96.63%. For readers comparing purely on theoretical return, these four titles from other studios sit above Scarab Boost, while Scarab Boost’s appeal rests more on its specific Hold and Win structure and Egyptian theme than on the RTP figure alone.

How to Play Scarab Boost Online

Scarab Boost can be tried in demo mode before any real-money session, which lets a player see how often the Hold and Win round triggers and how the Cash Collector symbol behaves without staking a balance. The full slots demo catalogue and the broader Slots category both carry free-play versions alongside real-money listings. 3 Oaks Gaming titles run at 72 casinos in our catalog, including operators such as Lucky7even, Lucky Vibe and Hercules Casino, though availability and any slot-specific promotions should be confirmed with the individual operator before depositing.

Conclusion

“Scarab Boost is a high-volatility Hold and Win slot for players who accept irregular payouts in exchange for a 5,000x ceiling” — Search-Casino Editorial Team

Scarab Boost delivers a fairly standard high-volatility Hold and Win package from 3 Oaks Gaming, with a 95.77% RTP that sits below the median of titles in our catalog and a 5,000x max win that lands roughly in the middle of comparable slots. It works best for players who already manage high-variance sessions deliberately, treat the demo mode as a way to learn the respin rhythm first, and are not chasing the highest RTP figure available in this mechanic group.
