The video slot industry has seen significant improvements over the last few years.

While there have been notable changes in how these games are designed, Betsoft Gaming remains at the forefront of innovation.

Giovanni’s Gems is one of their top releases.

As the name indicates, Giovanni’s Gems is a gem-themed slot set in a dark, mysterious cavern.

The background contrasts with the bright, colorful gemstones found during gameplay.

The owner, Giovanni, is present holding a torch to help you complete your adventures.

The game features high-quality 3D graphics and an inspiring musical score.

While the developer has mobile-optimized the game for all operating systems, my hands-on testing revealed that the user experience can vary significantly between desktop and mobile devices.

Session Timeline & Results

On March 2, 2026, I used my MacBook (Firefox) and my iPhone 17 Pro Max (Safari)’s 5G network to test Giovanni’s Gems by Betsoft.

I started at 6:11PM EST with $2,342.33 and finished at 6:33PM EST with $2,352.83.

I bet $0.30 per spin for 100 spins. I won $10.50, but it was a bumpy ride. I only recorded my MacBook session.

The first 10 spins started off pretty good, with some decent wins. I was very surprised.

However, the next 10 spins I hit a bit of a dry spell.

From the 31st spin to the 40th spin, I began to see more decent wins.

The next 10 spins were more of a dry spell, but from the 61st to the 70th, I began to see more decent wins.

I thought this game was like a roller coaster, but I was having fun.

From the 71st to the 80th spin, I had a dry spell, and from the 81st to the 90th spin, I saw more decent wins, until the 99th spin, when I triggered the free spins bonus round.

I ended up scoring a big win of $11.55 on the bonus round and stopped the game at the 100th spin.

I tested the spin, stop, and auto spin buttons, and they seemed to work okay.

My MacBook started to get a little hot, whereas my iPhone stayed cool.

I looked to see how much of the battery I used, and on my MacBook, it showed maybe 1-2%, whereas on my iPhone, it didn’t show I used any.

Features & Comparisons

I liked the free spins bonus round.

Compared to Event Horizon, I thought the overall game was a little worse, but the wins were great.

It was much more exciting having more steady wins playing Event Horizon, even though my session was lagging.

Gameplay & Symbols

Giovanni’s Gems is unlike most video slots. Instead of traditional paylines, you will find a 7×7 grid of symbols.

You have to depend on clusters to win. Clusters are made up of 5 matching symbols touching horizontally or vertically.

The major symbols are gemstones: coal, citrine, amethysts, sapphires, rubies, and emeralds.

Higher rewards come from pickaxes, torches, and sacks of gems.

This is a cascading game. Whenever a winning cluster is found, it vanishes while new symbols fall from above, potentially leading to more wins.

While the game does offer a gamble feature that will let you stake all or half of your normal wins in a guessing game, my main success came from the Diamond in the Rough feature.
