Jewel Thief Slot Review – Play Demo, Payout, Free Spins & Bonuses

Betting

You can play Jewel thief with a maximum bet of 3 coins. If you do, all paylines are activated. So I recommend playing this game with a maximum bet so you can activate all paylines and get more chances for higher profits. If you’ll choose to bet only 1 coin, only the middle payline will be activated and if you bet 2 coins the middle and the upper paylines are only activated. There are 6 winning combinations and the prices depend on the number of coins you bet.

Symbols and Paylines

Jewel Thief has unique symbols. It still has legendary bars though, safe dial, diamond and the Jewel thief logo. The Jewel Thief logo is a wild symbol. It can replace any symbols to complete any winning combinations. If you line up 3 Jewel thief Logos on the 1st payline you can win a jackpot price of 1500 credits. If you get all 3 Jewel Thief logos line up in the 2nd payline (upper line) you can get 3000 credits and if you get all 3 Jewel Thief logos on the 3rd payline (lower line) you’ll hit the jackpot price of 6000 credits. Very big price, isn’t it?

Export Mode

Another characteristic of this online pokie game is the expert mode. In expert mode, players can set the game in Auto play. Auto play allows the player to set the number of spins, so the game would spin automatically and they can also set when to stop the spin. With the expert mode on, players can just sit back, eat, drink, chit chat with other players and watch their credits grow bigger and bigger.

Jewel Thief Slot Review: Classic Crime Meets Reel Innovation

There’s something timeless about a good heist story. The tension. The risk. The sparkle of high-stakes pursuit. Now, imagine that feeling captured inside a slot machine. That’s what Jewel Thief brings to the table—though depending on which version you’re playing, the ride can feel completely different.

This slot title doesn’t just refer to one game, but at least two distinctive takes: a bold, feature-rich video slot from Sigma Gaming, and a stripped-down, old-school classic from Microgaming. Both fall under the same criminal caper umbrella, but one whispers, and the other shouts. Let’s walk through both and see which version might steal your attention.

Caught Between Two Reels: Which Version Are We Talking About?

Slot names aren’t always exclusive, and Jewel Thief is a great example of this naming overlap. On one end, we have the Sigma Gaming version, which feels like a modern, animated short film—complete with bonus games, free spins, and dramatic 3D visuals. On the other, Microgaming’s Jewel Thief opts for a nostalgic 3-reel layout that strips things down to basics, echoing the simplicity of land-based machines.

Both serve their audiences well. But if you’re someone who wants to understand where your money’s going—whether it’s chasing complex mechanics or just spinning for straightforward wins—it’s worth digging deeper into what each game really offers.

What’s the Storyline and Style?

Let’s start with the Sigma Gaming version, since it feels more cinematic. The entire setup revolves around the jewel heist theme. You’re thrown into a gritty cat-and-mouse chase between cops and a master thief. Think flickering neon lights, squad cars, sirens, and the glitter of high-value gems. Every symbol, from the policewoman to the necklace scatter, serves to paint that urban drama.

It’s all done in 3D animation, which gives this game a sense of movement and purpose. There’s almost a narrative unfolding as you play—especially once bonus rounds begin.

Now, shift gears to Microgaming’s version, and suddenly you’re in a much quieter scene. No flashing lights, no background cityscape. Just simple reels, bar symbols, safes, and that cheeky thief logo acting as the wild. It’s cleaner, faster, and not trying to wow you with visuals. For those who value speed and direct wins over theatrics, it’s got an old-school charm that’s hard to beat.

Symbols and Their Purpose

The Sigma version has quite a bit going on. Here are some of the key elements:

• Necklace (Scatter) – Triggers the free spins bonus.
• Bravery Medal (Wild) – Substitutes for everything except the scatter.
• Thief and Police Car combo – Opens up the hidden bonus game during free spins.
• Other thematic icons – Policeman, policewoman, dog, handgun, handcuffs.

Payouts are medium-tier, but they build fast once features start triggering.

In contrast, Microgaming’s version offers:

• 1-Bar, 2-Bar, 3-Bar Icons – Classic fruit machine stand-ins.
• Safe – Pays out moderate wins.
• Jewel Thief Wild – A simple but powerful substitution tool, helping create wins across three paylines.

Simplicity is the name of the game here. No scatters, no free spins, and certainly no bonus levels.

Bonus Features Worth the Risk

If you’re the kind of player who lives for bonus rounds, Sigma Gaming’s Jewel Thief has two major treats:

Necklace Free Spins

Triggered when 3, 4, or 5 necklace scatters appear anywhere on the reels. Players are rewarded with 10, 15, or 25 free spins, respectively. These free spins can be re-triggered—creating a strong sense of progression. And during these spins, you’ll sometimes stumble into the real treasure…

Necklace Bonus Game

This is a classic pick-and-win setup. You’ll need a thief symbol on reel 1 and a police car on reel 5 during free spins to trigger it. Once inside, you’ll pick from a selection of items, revealing coin prizes and multipliers that significantly bump up your total win. It’s satisfying, even if it doesn’t happen often.

By comparison, Microgaming’s slot has no formal bonuses. No free spins. No pick rounds. Just you and the reels. While that may seem limiting, there’s a certain beauty to it. It’s clean, efficient, and leaves little room for confusion. For some, that’s a major plus.

RTP, Variance & Payouts

Now let’s get down to numbers.

The Sigma version has an RTP of 95.14%, placing it slightly below the modern industry average. That’s balanced out by medium volatility, which means you won’t suffer long dry spells, but also shouldn’t expect to hit mega wins too frequently. It walks a middle path—and that’s ideal for most players.

The Microgaming version probably sits around 94% RTP, though exact figures are hard to come by. Volatility feels lower, which makes sense given the limited payline structure and absence of features. It’s more consistent, but the ceiling is lower.

If you’re chasing jackpot-level thrills, Sigma’s route is more rewarding. But for low-risk, fast play, Microgaming holds its own.

Compatibility & Playability

Sigma’s version was built with Flash, JavaScript, and HTML5, which makes it more adaptable—especially since Flash is all but obsolete now. It’s playable on desktop and most modern mobile browsers, though not all online casinos offer the mobile version yet.

Microgaming’s take is a bit older, meaning it’s more dependent on Flash or downloadable versions. That might be a drawback for players using phones or tablets, but on a desktop, it still runs smooth.

Both versions offer autoplay, though only Sigma gives you the joy of watching the story unfold between the reels.

Where Can You Play It?

Sigma’s version is available in over a dozen countries, including Sweden, Brazil, and Thailand. However, it may not be accessible in regions like New Jersey (USA) due to licensing restrictions.

Microgaming’s version has broader availability due to its age and wide distribution. You’ll find it across many well-known online casinos, often in the classic games section.

Want to try before you spend? Several platforms host free demos of both versions, so you can test the waters.

Who’s This Slot For? Let’s Talk Real Talk

If you’re a fan of bonus features, layered gameplay, and modern visuals, Sigma Gaming’s Jewel Thief should be your go-to. It offers enough complexity to keep things interesting without overwhelming casual players.

But if your taste leans toward simplicity, speed, and low-risk play, Microgaming’s version is a quiet little gem. It reminds you that not every session needs flashing animations and complex bonus structures. Sometimes, a good old-fashioned wild symbol and three clean paylines are all you need.

Final Thoughts: Which Side of the Law Are You On?

Jewel Thief might wear the same name across two different slots, but the experience you get depends entirely on which version you spin. Sigma delivers a more cinematic and feature-rich journey, while Microgaming sticks with clean, no-nonsense mechanics that cater to purists.

In the end, both games celebrate the heist motif in their own way. Whether you’re in it for the drama or the discipline, there’s room at the reels for your style of play.

And if you haven’t tried either yet, now’s a great time to give them a spin—just remember, in the world of Jewel Thief, every spin might bring you closer to the ultimate heist.

Real Questions Players Ask: Jewel Thief Slot FAQs You’ll Want to Know

What’s the difference between the two Jewel Thief slot versions?

There are two major versions: one by Sigma Gaming and another by Microgaming. The Sigma version offers 5 reels, 50 paylines, and features like free spins and bonus rounds. Microgaming’s version is a simpler 3-reel slot with just three paylines and no extra features—perfect for fans of classic slots.

Can you trigger free spins in Jewel Thief?

Yes, but only in the Sigma Gaming version. Landing 3 or more necklace scatter symbols will activate the Free Spins round. You can win up to 25 spins with potential for re-triggers and bonus features during the round.

Is the Jewel Thief slot available on mobile devices?

The Sigma version is built using HTML5, so it runs smoothly on most modern smartphones and tablets. The older Microgaming version might be limited to desktop due to its Flash-based framework, unless the casino offers an updated format.

How high can the payouts go?

The Microgaming version caps out at 6,000 coins, which is solid for a 3-reel slot. The Sigma version doesn’t list an official max win, but the combination of free spins, multipliers, and bonus rounds suggests a comparable or higher win potential.

Where can I try the Jewel Thief slot for free?

Many online casinos offer demo versions of both games. Sites like SlotsMate, CasinoNearYou, and even SlotCatalog allow you to spin the reels without spending real money—ideal if you want to get a feel for the gameplay first.
