Giovanni's Gems

Giovanni’s Gems by Betsoft is a video slot featuring a 7×7 grid with no traditional paylines; wins are formed through cluster pays when you land five or more matching symbols adjacent to each other either horizontally or vertically. Cascading reels are at the core of its gameplay: winning clusters explode and the gaps are filled by new symbols dropping in, potentially triggering consecutive wins in a single spin. The game includes the Giovanni’s Diamonds feature, where Coal symbols next to winning clusters are transformed into Diamonds — the highest paying symbol in the game — during the base game. During free spins, all coal symbols are treated as Diamonds automatically. The Free Spins feature is triggered by landing five or more Giovanni scatter symbols anywhere on the grid; depending on how many scatters land, the number of free spins awarded ranges up to fifty. There is a gamble (“Double Up”) feature available after any win, where you can attempt to double your win by guessing the correct colour of a hidden card. The theme is mining for uncut gems in a hidden cave, with a forested backdrop and gemstones of various shapes and colours, and Giovanni himself appears with a torch illuminating the reels. Autoplay is supported, allowing up to one hundred automatic spins. Wild symbols are not part of this game.
