40 Shining Jewels

40 Shining Jewels Slot Review — CT Gaming

40 Shining Jewels is a classic-style video slot from CT Gaming, a provider licensed by the Malta Gaming Authority and the Bulgarian Gaming Board, released on 13 August 2016 and still running across a number of online casinos today. It spins on 5 reels and 4 rows across 40 fixed paylines, carries a documented RTP of 95.9% and sits in the medium volatility band, with bets running from 1.0 to 400.0 per spin. The core mechanic pairs standard wild and scatter symbols with a gamble round for players who want to press their luck on a completed win.

Core Gameplay Experience

The 5-reel, 40-payline layout keeps the grid busy without overwhelming it, and wins land often enough on medium volatility to keep the reels feeling active rather than static. Bet sizing from 1.0 to 400.0 gives a wide spread for both cautious and larger stakes, which is typical for CT Gaming’s catalogue of land-based-style titles.

Visually the game leans into a treasure-and-gemstone theme: diamonds, gold detailing, a crown and deep red and purple tones sit alongside bright jewel symbols on the reels. This puts it in the same thematic space as other Adventure & Treasure themed slots, where gold and gem iconography is used to signal value on the paytable rather than to carry a story.

The pacing is deliberately simple: no cascading reels, no expanding grids, just a straightforward spin-win-gamble loop. That makes it easy to read at a glance but also means the session rhythm stays fairly uniform from spin to spin, which some players will find calming and others will find repetitive over long sessions.

Features and Mechanics

The documented feature set is short: a wild symbol, scatter symbols, an RTP range designation and a gamble (double-up) game. Per CT Interactive’s own game information, the wild substitutes for standard symbols to help complete winning combinations across the 40 paylines, while scatters pay independently of the payline structure rather than needing a specific line to land on. The gamble round lets a player risk a completed win on a double-or-nothing style call, a mechanic shared with several other CT Gaming titles rather than unique to this one. No bonus-buy option is part of the documented feature set — the mechanics here run only through base-game spins, wilds, scatters and the gamble round, without a purchasable entry point into a bonus feature.

RTP, Volatility and Payout Model

40 Shining Jewels pays back a theoretical 95.9% of stakes over the long run at medium volatility, meaning wins are neither concentrated in rare big hits nor smoothed into constant small returns. That 95.9% figure sits in the 41st percentile of the 4,445 slots in our catalog with a published RTP (catalog median 96%), so it lands slightly below the midpoint of the games we track rather than at either extreme. The medium volatility label itself is shared by roughly a third of our catalog — 33% of 4,737 titles carry the same profile — which makes the swing pattern here a common one rather than an unusual choice. The listed RTP range feature indicates that some deployments of this title may be configured with a different published percentage depending on the operator’s build; the 95.9% figure used throughout this review reflects the version tracked in our catalog.

Similar CT Gaming Slots — Comparison

Among CT Gaming’s medium-volatility, 11-to-50-payline titles, 40 Shining Jewels ranks 23rd of 45 games by published RTP, putting it in the lower-middle of that comparable group rather than at either end. Fire Egg and Halloween Double Hot post the highest RTPs of this group, while Golden Acorn matches 40 Shining Jewels almost exactly on both RTP and paylines, making it a close alternative for players who liked this session’s pacing.

Similar Gamble Feature Slots from Other Studios

Blue Star offers the highest ceiling of the four compared titles here, while Cave of Fortune trades a lower RTP for high volatility rather than the medium profile the other three share. Players who liked 40 Shining Jewels for its steady medium-volatility rhythm are better matched to Wild Volcano or Arabian Nights 2 than to the higher-swing Cave of Fortune.

How to Play 40 Shining Jewels Online

CT Gaming titles run at 66 casinos in our catalog, including operators such as PlayMojo, ViciBet and Gunsbet, though availability at any single operator should be checked before playing. A demo version lets you see the wild, scatter and gamble mechanics in action without staking real money, which is a practical way to judge whether the medium-volatility pacing suits your bankroll before committing funds. The game can be found alongside other titles in the Slots category and the wider demo game directory, and its provider page, CT Interactive slots & casinos, lists other releases from the same studio. The gamble mechanic here also links it to the broader set of slots with a Gamble Feature, useful if that double-up option is a specific draw for you.

Conclusion

“40 Shining Jewels delivers a steady, jewel-themed medium-volatility session without chasing a large ceiling — a fit for players who value predictable pacing over rare big hits.” — Search-Casino Editorial Team

Overall, 40 Shining Jewels reads as a functional, unhurried entry in CT Gaming’s catalogue: 40 paylines, a 95.9% RTP that sits in the lower-middle of comparable games, and a feature set limited to wilds, scatters and a gamble round. It suits players looking for a calm, medium-volatility spinner they can test in demo mode first, rather than those specifically hunting the highest possible max win.
