4 Secret Pyramids Slot Review
4ThePlayer have built a recognisable style across their portfolio, and 4 Secret Pyramids continues that tradition with distinctive progression mechanics housed within an Egyptian-themed adventure. Released in July 2022, this instalment in the 3 Secret Cities series introduces the signature BONUS↑UP trail system—a four-tier pyramid progression mechanic that rewards consistent play and strategic decision-making. The game sits comfortably in the high volatility space with a 95% RTP, offering substantial win potential for players willing to chase the pyramid climb.
Base Game & Features
4 Secret Pyramids operates on a 5-reel, 4-row grid delivering 1,024 ways to win. The base game mechanics are deliberately restrained, positioning the bonus features as the primary focus. With a hit frequency of approximately 32.34% (one winning combination every three spins on average), the base game creates deliberate pacing—players experience quiet stretches that build anticipation toward the progression-driven bonus rounds rather than constant small wins. This intentional design philosophy means casual base game wins exist, but the real engagement comes from chasing the pyramid advancement system.
The quiet base game between bonus triggers is entirely intentional, creating a compelling dynamic where each advancement feels genuinely earned. Symbol payouts follow standard construction with lower-paying card values and themed Egyptian icons representing higher prizes. The fundamental mechanics are straightforward execution, but they serve their purpose: directing player attention toward the progression mechanics that define the experience.
4 Secret Pyramids Bonus Features
The centrepiece of 4 Secret Pyramids is the BONUS↑UP trail—a four-tier pyramid progression system that genuinely sets this game apart from standard Egypt slots. Landing three pyramid scatter symbols on reels 1, 3, and 5 triggers the Pyramid Free Spin Bonus, initiating entry into this quest-like progression journey.
The Four Pyramid Tiers
Each pyramid tier represents a distinct progression level with escalating rewards and stakes:
- Tier 1 – Desert Pyramid: 15–20 free spins with a 4x–6x multiplier. Maximum win potential reaches 20,000x your stake. This entry-level tier provides a solid foundation for progression.
- Tier 2 – Canyon Pyramid: Players face a strategic choice: Option A delivers 20 free spins at an 8x–11x multiplier, whilst Option B offers 40 free spins at a 6x multiplier. This tier maximises player agency—you select the risk/reward profile that suits your strategy. Maximum win potential climbs to 35,000x stake.
- Tier 3 – Lake Pyramid: 30–40 free spins with a 6x multiplier. The tier maintains 35,000x maximum win potential whilst offering more spins for potential stacking sequences.
- Tier 4 – Golden Pyramid: The pinnacle achievement delivers 35–55 free spins with a 10x–15x multiplier. This tier alone enables the game’s maximum win of 55,000x your stake, representing the true endgame reward for reaching the summit.
Each advancement through pyramid tiers feels genuinely rewarding—the escalating free spins (from 15–20 to 35–55), increasing multipliers (from 4x–6x to 10x–15x), and progressive max win increases (from 20,000x to 55,000x) create tangible progression with real stakes at each level.

Pyramid Pick Mechanic
The Pyramid Pick mechanic transforms free spins from automatic execution into interactive decision-making. During bonus rounds, you select blocks on each row, choosing from free spins, multiplier enhancements, stacked symbols, or bonus progression markers. This interactive element injects genuine agency into the bonus experience—your strategic choices directly influence win potential, making each bonus round feel participatory rather than predetermined.
Bet Modifiers & Bonus Buy
4 Secret Pyramids provides multiple pathways to bonus engagement:
- Extra Bonus Bet: Costs an additional 25% per spin. Increases the probability of triggering free spins during base gameplay.
- Double Bonus Bet: Costs an additional 25% per spin. Doubles your free spins or multiplier values during bonus rounds, effectively doubling the tier rewards.
- Combined Modifiers: Deploy both modifiers together for a 50% additional spin cost, maximising free spin trigger probability and bonus reward enhancement simultaneously.
- Bonus Buy Options: Direct pyramid tier shortcuts available at 60x stake for Desert Pyramid access, 120x for Canyon Pyramid choices, and 200x for direct Golden Pyramid access. Remarkably, the 95% RTP remains consistent across all bonus buy tiers and modifier combinations—a transparent and fair approach.
The RTP transparency across bonus buy tiers is particularly honest and fair. Regardless of which route you take—natural progression, bet modifiers, or direct bonus purchases—the house edge remains unchanged at 95%. This consistency removes the suspicion that certain options are inherently disadvantageous, allowing players to customise their experience with genuine fairness guarantees.

Mobile Experience: Big Reel Portrait Mode
4 Secret Pyramids is fully optimised for mobile devices. The Big Reel Portrait Mode is a standout feature, offering vertical stacking with right-to-left spin mechanics that occupy up to 80% of the mobile screen. This demonstrates significant thought in mobile optimisation. Players can also select Classic Mode if they prefer traditional display formats. The graphics remain crisp and clear in both modes, with excellent focus on high-paying symbols and important features—the game looks equally compelling whether you’re playing on landscape desktop or vertical smartphone.
Our Honest Verdict
4 Secret Pyramids delivers a proper journey with genuine stakes at each tier for its target players. The BONUS↑UP mechanic is what genuinely sets this game apart, creating a compelling quest-like experience rather than standard bonus-chasing mechanics. The progression system creates engagement—reaching the Golden Pyramid genuinely feels like an achievement, particularly when you unlock it naturally rather than purchasing access.
However, honest assessment demands acknowledging the trade-offs. The 95% RTP sits below industry standard and is notably lower than 3 Secret Cities’ 96.5%—a decrease that matters for long-term play. Over extended sessions, this 1% difference translates to meaningful additional house edge. The high volatility with 32.34% hit frequency means you’ll need discipline during quiet stretches; base game quiet periods are intentional but undeniably present. Reaching the Golden Pyramid genuinely requires either significant bankroll commitment or fortunate bonus convergence—the 200x stake bonus buy isn’t a casual decision.
The 55,000x maximum win is achievable and thrilling on paper, though reaching it realistically requires optimal pyramid progression, bonus stacking, or substantial bankroll investment. For high-volatility enthusiasts, this win potential and the interactive bonus mechanics provide genuine excitement that justifies the RTP trade-off. The progression mechanics keep the experience fresh during long sessions rather than feeling repetitive.
4 Secret Pyramids excels for players who appreciate progression-based gameplay and don’t mind the RTP reduction in exchange for distinctive mechanics and strategic depth. If you’re chasing frequent wins, prefer lower-variance entertainment, or value maximum RTP returns, look elsewhere. But for those willing to climb the pyramid and embrace the quest dynamic, this game delivers meaningful engagement with every tier advancement feeling earned.
