Cave of Gems Dice Slot Review: A Nitro-Fueled Slot Worth Exploring

A goggle-wearing goblin guards a cave full of colourful gems in Cave of Gems Dice by BF Games, and he's surprisingly generous once you figure out his Nitro system. 

The game kicks off on 5 reels and 3 rows, featuring 30 fixed lines, with a 96.08% RTP, medium volatility, and a top payout capped at 750x. Above the reels, a four-level jackpot ladder displays Mini, Minor, Major, and Grand prizes.

Each reel has a Nitro counter above it, and landing Nitro potion symbols fills these counters up to 3. Once a counter maxes out, that entire reel transforms into a Persistent Wild for the next 3 spins. Trigger another Persistent Wild on a different reel, and all active countdowns reset to 3 again. Get all 5 reels of Wild simultaneously? That's an instant 200x your bet.

Before the Free Games chaos began, my base game returned wins between 0.4x and 2.2x my bet, mostly from gem combinations, while the Nitro counters slowly climbed. Nothing remarkable, but the anticipation of watching those counters fill kept every spin interesting.

So why do I already sound like something big happened? Well, it did.

Second spin of my session, boom, five Treasure Chest Scatters appeared and awarded 20 Free Games. Now that's what I call a find. The fifth spin added 5 more, and the fifteenth spin threw in another 10. I could do this all night. 

During Free Games, a Grand Nitro Meter tracks every Nitro symbol that lands. In case you hit 15 on that meter, you pocket 500x your bet instantly. There's also an Explode Feature that randomly triggers when the meter reaches at least 3, scattering Bomb Wilds across the grid equal to the meter value.

Between the Persistent Wilds stacking across multiple reels, the retriggering Scatters refusing to stop, and the Explode Feature dropping Bomb Wilds at random moments, my 50 Free Games delivered 191.7x my bet by the time the goblin finally let me leave his cave.

Jokes aside, for a slot with this much happening beneath the surface, Cave of Gems Dice never feels overwhelming, just rewarding.

PROS

• Persistent Wilds stack and reset each other
• Free Games, thanks
• Grand Reward pays 500x at meter max

CONS

• None

777 X-Mas Gifts: Slice Fruits for the Holiday and Win up to 400x Jackpots

BF Games wrapped a fruit machine in Christmas paper and added a Pick and Click bonus that lets you open gift boxes hiding prizes up to 400x your stake. 777 X-Mas Gifts spins on a 3x3 grid with 5 paylines, 94.01% RTP, medium volatility, and 574x max win potential. It's never too late for gifts, so let's see what this slot has in store for me.

The candy-striped Triple 7 works as Wild and carries an extra trick during Free Spins, where each one that lands pays 20x your bet regardless of line placement. Three golden star Scatters on a payline unlock 5 Free Spins on an alternate reel set, and retriggering adds another 5 to the count.

As they should, fruit combinations kept my balance steady throughout the session, with bells and watermelons paying 15x for three of a kind and smaller wins from grapes and oranges filling the gaps. I collected hits between 0.8x and 3x my bet regularly enough that the grid never went completely cold.

A four-tier jackpot system sits above the reels too, with Grand at 400x, Major at 100x, Minor at 20x, and Mini at 10x your bet.

What surprised me was the X-Mas Rewards feature appearing randomly mid-session. Nine wrapped presents covered the screen, and I tapped through four of them before matching three Minor symbols for 20x my stake. The Grand at 400x stayed hidden, but that instant bonus added something the base game lacks on its own.

Two Wilds dropped across my 5 Free Spins, each triggering that 20x payout and pushing the round total to 28x my bet. Overall, the 777 X-Mas Gifts slot is a pretty average entry by BF Games that doesn’t try to do anything new. If you like fruit-themed slots, be my guest but if you want something more involved, you might want to scroll down and check out some other titles. 

PROS

• X-Mas Rewards Pick and Click adds variety
• Wilds pay 20x during Free Spins
• Medium volatility keeps wins steady

CONS

• 94.01% RTP sits below average
• 574x max win is modest
• Free Spins only award 5 rounds

777 Winter Hit Dice: A Frosty 3x3 Grid With a 234x Ceiling

BF Games keeps things minimal with 777 Winter Hit Dice, a 3x3 grid classic fruit slot dressed for winter. Five paylines, 96.16% RTP, low volatility, and a 234x max win that matches the slot's ambitions.

In my opinion, for a simple slot with simple aesthetics, this one should have been more fruitful. My session dragged through spin after spin of near-misses and empty grids, with wins landing so rarely I started questioning whether the reels were frozen solid. When something did connect, it paid between 1x and 1.5x my bet, barely enough to notice.

The Triple Seven works as a Wild and substitutes for all symbols, but Free Spins come only from the snowflake Scatter. Three Scatters award five spins on an alternate reel set, where each Wild pays 20x your bet alongside line wins. Retriggers add five more spins, though none appeared in my session.

That said, the highlight arrived late, a triple 7 line that pushed my balance up by 12x my stake. One decent hit across an entire session doesn't exactly scream replay value, especially when the max win sits where it does. The journey there feels like trudging through snow without boots.

Low volatility usually means frequent small wins, but 777 Winter Hit Dice missed that memo. The winter theme looks fine, the mechanics work as expected, but the experience left me cold in ways the designers probably didn't intend.

PROS

• Dice Wild substitutes for everything

CONS

• Wins were frustratingly rare
• 234x max win
