Set inside a dark mine that you'll get to explore with the enthusiastic Giovanni, this slot features a 7x7 screen full of diamonds, gems, and crystals you can collect to get richer. Use any device you want to play for real money and you can earn your share of payouts up to a staggering 1,000,000 coins.
As you can expect from a BetSoft slot machine, Giovanni's Gems features the studio's remarkable 3D graphics but also a number of its popular bonus features. The slot's cascading reels ensure you always get a second chance to bank a prize as you play while the free spins bonus, double-up game, and symbol swap function are there to give you even more opportunities to earn a profit but without paying anything.
Don't let the 7x7 screen fool you into thinking this slot is hard to play because the reality is quite different. With the intuitive controls on your left, you can easily adjust the size of your bet by choosing the value of your coins and increasing your bet level multiplier up to 5. The smallest stake is 0.30 credits (0.01 per coin) while the highest bet is set at 150 credits. Once you're done setting up your bet, just press the spin button to start wagering or tweak the Auto Play controls for a hands-free playing experience.
What's quite unusual about this slot machine is that it doesn't have any paylines. Instead, it relies on special "cluster pays" mechanics to produce prizes at real money online slots sites. The payouts can be triggered by 11 symbols, every one of which offers prizes that are represented in coins and increase along with your bet level. Playing the slot for real cash on bet level one will give you a chance to earn payouts ranging from 3 to 3,000 coins per cluster. Increase your bet level to five, though, and you can expect better returns of up to 15,000 coins per cluster. And thanks to the special mechanics, this slot guarantees that you always get a free chance to earn a second win right after any payout.
If you prefer to gamble on the move, you can also enjoy this slot on your iPhone, iPad, or Android mobile device. You'll enjoy the same sleek experience when playing on a phone but with fewer mobile-optimized controls. Find the bet controls in the hidden menu in your top-left corner to adjust your stake and then just hit the spin button on your right to get started.
You can only collect money in the Giovanni's Gems slot by forming clusters of matching symbols on any reel and in any direction possible. Clusters are groups of five or more identical symbols that are adjacent to each other in any way. By joining symbols, you can form clusters with up to 25 symbols at a time to get closer to the game's jackpot. The slot also explodes all winning clusters, letting fresh new symbols fall down in their place to give you another chance of winning a prize but without paying anything extra.
The most valuable icons you can collect when playing for real cash are the Giovanni and coal symbols. The Giovanni symbol is basically a scatter symbol that can pay in any location, regardless if it forms a cluster or not. Collecting 5-25 of these symbols during a round will get you instant payouts of up to 1,500 coins plus a bonus of up to 50 free spins. And to make things even more exciting, any coal symbol that appears next to a winning cluster during the free spins will automatically turn into a diamond free bet casino symbol, which can pay up to 15,000 coins per cluster.
As a final reward, the slot also offers you an old-school gamble feature. This feature can be accessed by pressing the "Double Up" button right after you win a payout. Like most gamble functions, this one lets you guess the colour of the next card to double your full prize, double half of it, or lose it should you make a wrong guess.
Giovanni's Gems is a slot designed mostly for punters with a taste for immersive medium-volatility games. If you are not a player who doesn't mind risking too much money and are more into modern slot machines than classic games, Giovanni's Gems will be worth trying out. Not only a game that can be highly entertaining, but this BetSoft slot can also pay big prizes of more than 1,000,000 coins when played for real cash, although with a hit ratio as high as this game has, getting to payouts that are so big would likely happen quite rarely.
For players who are looking for massive prizes and don't mind taking a bigger risk to get them, there are a couple of high-variance slots from BetSoft that you may want to try. For a slot with 6 reels and a similar payout potential, you can check out BetSoft's vampire-themed Blood Eternal slot. And for a unique slot machine that lets you pick your own volatility, you can also try out the Good Girl Bad Girl slot machine. Make sure to check out some of our recommended online casinos to find these slots and more available for real money playing and get yourself an attractive welcome bonus right after you sign up.
