Jewel Boost Reels Slot Review

I don't know who looks at the Crown Jewels and thinks "I should flatten that crown with a mallet 🔨 and shove the orb down my trousers," but Thomas Blood gave it a shot in 1671.

He got caught at the Tower gates, demanded an audience with Charles II, and the king was so charmed he gave Blood a full pardon and a country estate. 🎉

Walking away from the most famous jewels on the planet, richer than you arrived, is either a once-in-history miracle or a Tuesday at the slots.

I'm hoping Mascot's Jewel Boost Reels slot has that kind of generosity baked in, because I'd rather win big than have to smuggle jewels out in my pants. 😫

Gameplay

Alright, what do we have here? Mascot has taken the easy route with the design of this game, giving it a sparkly green background, throwing in some shooting stars, and calling it quits.

Admittedly, the fruits we see on the reels are super 3D and life-like, which is pretty cool. The game doesn't translate as well as you'd imagine to a mobile device. That's because there is a lot of background.

The grid stays about the same size in both portrait mode and landscape mode. So it's not ideal, but it's still playable on your smartphone.

The 5x3 grid has 10 paylines, the RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.

RTP needs to be considered in conjunction with a game’s volatility rate. is 96.24%, volatility is high, and the max multiplier is 2,000x. The max win is $100,000, with bets ranging from $0.10 to $50.

The lemon symbol pays 2.5x for 5-of-a-kind, and the grapes match it. The watermelon pays 4x for a full line, and the orange steps up to 5x with better mid-tier payouts across the board (2x for 4-of-a-kind, 1x for 3).

A green gem in a gold baroque frame pays 7.5x for 5-of-a-kind. The purple gem jumps to 25x, and the red gem tops the paytable at 60x.

The Wild symbol lands on reels 2, 3, and 4 only. It replaces all regular symbols, expands to cover the full reel, becomes sticky, and awards 1 Respin.

Features

FREE RESPINS:

When a Wild lands, it expands to fill the entire reel, locks in place, and triggers 1 Free Respin.

The best run would be all 3 middle reels covered in sticky Wilds, with reels 1 and 5 left spinning. If 2 Wilds land on the same spin, you still only get 1 Free Respin, but each Wild on a later respin triggers another.

That's the whole feature. Expanding sticky Wilds and respins, nothing else.

GAMBLE:

After any winning spin, you can enter the Gamble game. The round reveals 1 card face-up, and you pick from a grid of 14 face-down cards. If your card is higher, the win doubles; if it's lower, you lose your moolah. A tie keeps things as they are.

The Ace is the highest card and can only be beaten by the 2. The multiplier starts at 2x per correct guess, bumps to 3x after 6 revealed cards, 4x after 10, and 5x after 12.

The Gamble caps at 2,000x the total bet, and you can collect between picks (worth remembering after a few correct guesses when greed starts whispering).

ANTE BET:

Mascot Gaming calls this the "Boost." The Boost doubles your bet and increases the chances of triggering Free Respins, and you can toggle it on or off between spins.

Performance

I didn't run into any issues while testing this game. The only thing that needed boosting was my balance, not the frame rate.

Maximum Win

At the top bet of $50, the max multiplier of 2,000x puts the max win at $100,000. Bets start at $0.10.

Conclusion

The money in Jewel Boost Reels slot comes down to how far you're willing to push the Gamble featureThis feature allows you to gamble your current winnings. It usually takes the form of guessing what color and/or suit a facedown card will reveal itself to be. A correct guess on the color pays 2x, while a correct guess of the color and suit pays 4x your bet.. The reels alone won't get you near the 2,000x ceiling, so every big win runs through the Gamble game but there’s a real chance of losing it all on a single card.

For a high-volatility slot, 2,000x is a weak ceiling, and Mascot Gaming hasn't told us what the Boost does to the RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.

Balanced players can squeeze value from chaining sticky Wilds, but I keep thinking about what this game could've been with multipliers layered on top. And if you're a max-win hunter, 2,000x won't cut it.

Jewel Boost Reels slot is a fruit-and-jewels game with one idea: sticky Wilds into a Gamble. This game works if you like flipping cards for 2,000x, but anyone looking for reel-driven payouts should look elsewhere.
