Cave of Gems Online

Generous multipliers, a bonus buy feature, and a unique bonus round await you in Cave of Gems by BF Games. Released in August 2024, this slot deserves the attention of all players, regardless of their budget. The winning potential is truly high, and high rollers all have a chance to win.

Cave of Gems has an average rating, which is unusual for this developer. It’s therefore ideal for all players, from beginners to experienced gamers, even those on a budget.

Symbols and prices

Despite its unusual design and presentation, the Cave of Gems slot machine uses classic “win-win” mechanics. The game grid consists of 5 reels and 3 rows of symbols, and winning combinations can be formed on 30 fixed paylines, from left to right. Wins can only start on the leftmost reel, with symbols appearing on adjacent reels.

Before starting a game and for each new round, you must select a bet between $0.30 and $90 per round. This bet can be changed before each new round.

Symbols

The highest paying symbols are represented by gems, which the goblin sought in the underground mines. These symbols rarely form winning combinations, but offer multipliers ranging from 0.15x to 1.5x. Please note that the Blue Sapphire symbol can form a winning combination with two symbols on a payline, while all other winning combinations begin with three symbols on a payline.

Card symbols offer small payouts ranging from 0.03x to 0.45x the stake.

The Scatter symbol triggers free spins and offers wins of 1.8x to 4.5x the stake for three to five symbols on the reels.

The Goblin symbol acts as a Wild: it substitutes for other symbols on the paytable and increases the frequency of winning combinations. The Goblin also forms its own winning combinations on paylines of two to five symbols, with multipliers ranging from 0.06x to 3x.

Features and bonuses

Cave of Gems stands out because of its bonuses. The developer attempted an original approach, and I think the result is a success.

Persistent Wild Function

Nitro symbols can appear on reels (1, 2, or 3 per spin), adding a charge to the meter above the corresponding reel. When the meter reaches 3, the reel transforms into a persistent Wild: all its positions then become Wilds. This reel remains active for 3 spins.

When a Wild reel is active and you trigger this feature on another reel, the spin counter of the first reel is also reset to 3. You can transform several reels into persistent Wilds for extended periods and thus win big by forming multiple winning combinations.

Furthermore, if all 5 reels become persistent Wilds simultaneously, you win an instant payout of 200 times your stake.

Free tours

Landing 3, 4, or 5 Scatter symbols on the reels triggers 10, 15, or 20 free spins respectively. In the bonus game, you don’t pay for spins and you benefit from all the features of the base game, including the persistent Wild mechanism, which triggers much more frequently during the bonus round.

Grand Reward Function

If you land 15 Nitro symbols, a special feature will be activated. The symbol counter will be reset on each reel, but you will receive an instant win of up to 500 times your stake.

Explode function

This random feature can only be activated during free spins and if you land 3 Nitro symbols above any of the 5 reels. A number of Wild symbols will then appear on the reels. Their placement is random, but their number corresponds to the Nitro level displayed above each reel. The more Wild symbols there are, the higher the frequency of wins and the greater the bonus potential.

Bonus purchase functionality

You can instantly activate free spins by wagering a certain amount:

• 10 rounds – 50 bets
• 15 rounds – 90 bets
• 20 rounds – 130 bets

RTP and Volatility

With its medium volatility and a base RTP of 96.08%, Cave of Gems offers optimal win frequency and size. Even with a small budget, you can win big. The high frequency of small wins encourages you to play longer, and longer playing sessions benefit from an increasing RTP.

Conclusion

Cave of Gems features high-quality graphics, captivating bonuses with expanding Wilds, and a free spins round. Random events can trigger significant wins at any time. Purchasing bonuses allows you to instantly unlock the slot’s full potential.
