Stones And Bones Slot by Genii

Stones And Bones leans hard into its prehistoric setting, and the commitment shows. The reels sit against a sun-baked savannah dotted with palms and distant volcanic peaks. Woolly mammoths, saber-tooth tigers, and a cooked brontosaurus rib fill the high-pay slots, while the card values get the full cartoon treatment as carved bone-letters (yes, even the 10 becomes a stone wheel "O"). It's silly. It's also weirdly endearing, the kind of Flintstones-inspired art you don't really see anywhere else in Genii's catalog.

The five-reel, three-row layout runs 30 adjustable paylines. The STONES & BONES logo is the wild, paying 2,000 coins for five and standing in for everything except the two scatters. And here's where it gets unusual: there are three separate scatter symbols doing three different jobs. The red-haired Cavewoman triggers free spins. The Caveman is a pure pay scatter, awarding 3, 10, or 30 coins times your total bet on top of any line wins, with no feature attached. The Dinosaur scatter fires the Age of Eggcitement pick bonus.

Three Cavewomen award 7, 10, or 12 free spins with every win doubled, and retriggers are possible. The Age of Eggcitement bonus is a clean pick-3-of-5 dinosaur eggs round, prizes multiplied by the triggering bet. The genuinely interesting bit? The dino bonus can trigger DURING free spins, which is rare for Genii and stacks nicely with the x2 multiplier already running.

Bets run from $0.01 up to $75 across a 4-tier chip and 10-tier coin setup, default $3. RTP sits at 96% with medium volatility, so swings stay reasonable. What's missing is worth flagging though: no buy bonus, no gamble, no wild multiplier, no random wilds. For 2014-era Saucify engine, that's fine. For 2026 players raised on Pragmatic, it'll feel bare. But the three-scatter design and that during-FS bonus trigger give it more strategic texture than the visuals suggest.
