Stones And Bones Slot Overview
The Flintstones never licensed this one, but the family resemblance is doing a lot of work. Cartoon cavemen, a purple woolly mammoth, a slab of meat the size of a car roasting over an open fire. What lifts it above the costume is that three separate symbols act as scatters here, and each one does a completely different job.
The reels are 5x3 over 30 paylines you can dial down to one, which is the kind of control almost nobody uses any more. A red-haired cavewoman starts the free spins. A pterodactyl opens a pick round called Age of Eggcitement. And a bearded caveman simply pays cash wherever he lands, triggering nothing at all. Three trigger symbols is a generous count for a 2016 line slot.
No buy button, no tumbles, nothing sticky. It runs on paylines and patience.
Theme & Design
The art is committed, and that counts for most of the appeal. The reels hang inside a frame of bleached bones lashed together with twine, floating above a sun-baked orange savannah with rock mesas on one side and smoking cone volcanoes on the other. Card ranks are carved out of skeleton parts: the A is a pair of bones braced by tusks, the K a femur jointed at the knee, and the 10 is a chipped stone wheel with a volcano visible through the hole. That wheel is the best small idea in the set.
Premiums each sit on their own colour block, so the grid reads fast even mid-spin. Purple behind the mammoth, green behind the saber-tooth's orange face, night-blue behind the rib on the campfire. Cleaner than most dinosaur slots of this vintage manage. One clear misstep, though: the title logo is spelled in cream bone letters against white clouds, so the second word almost vanishes into the sky above the reels.

Features & How They Work
Cavewoman Free Spins
Three or more cavewomen anywhere award 7, 10 or 12 free spins for three, four or five of her. Every win in the round pays double, and that doubling applies to caveman scatter pays as well as payline wins. The round retriggers from inside itself. Bet size and line count stay locked to whatever the triggering spin used, so there is no dropping to a single line to stretch the spins out.
Age of Eggcitement
Three or more pterodactyls anywhere open the pick round. Five dinosaur eggs appear, three get cracked, and each one holds a cash prize scaled to the bet that triggered it. Fixed picks, no ladder, no second stage. It resolves in seconds.
The part worth knowing is that it also triggers during free spins, which Genii usually blocks. Prizes won that way are not doubled by the free spins multiplier, since they are tied to the triggering bet rather than paid as a spin win.
The Caveman Who Just Pays
The bearded caveman is a scatter that leads nowhere. Three, four or five of him anywhere pay 3, 10 or 30 times total credits wagered, added on top of whatever the paylines return on the same spin. A steady drip rather than a bonus, and it is the reason the low-value stretches feel less barren than the paytable suggests.
Logo Wild
The bone-lettered logo substitutes every symbol except the scatters, and it also pays the top line in the table at 125, 750 and 2,000 coins for three, four and five. Five of them on a payline is the largest single hit available, and it doubles inside free spins. No multiplier attached to the wild, no stacking, no expansion, and it lands on any reel.

How Stones And Bones Plays
Sessions move in small increments. Nothing pays for two of a kind, so plenty of spins land flat, and the ones that connect usually hand back a slice of the stake rather than a jolt. The default $3 across 30 lines drains slowly and predictably, which is exactly what a game pitched at this end of the volatility range is supposed to do.
What stops it going numb is having three symbols worth watching at once. Two cavewomen on screen means one thing, two pterodactyls another, and a loose scattering of cavemen pays whether or not it builds toward anything. That is far more near-miss surface than a single-trigger slot gives, and it makes the base game noticeably less monotonous than 30 paylines of cartoon bones ought to be.
The bonus is where it flattens out. Doubling every win is honest arithmetic, but the round plays like the base game with bigger numbers attached: same reels, same symbols, no meter climbing anywhere. You will likely finish a seven-spin round feeling like nothing much changed. The egg pick lands better, mostly because it is the one moment the reels stop and something else happens on screen.
Pros & Cons
Pros
- Theme carried all the way down to the low symbols, with bone-carved card ranks and a stone-wheel 10
- Three separate scatter symbols keep far more of the grid meaningful than a single trigger would
- The egg bonus can fire during free spins, which most games this old lock out
- Wide betting room, from a penny up to $75 a spin
Cons
- Free spins add a flat double and nothing else, no new symbols and no rising multiplier
- The pick round is fixed at three eggs from five, so there is no build-up and no decision that matters
- No buy feature, no gamble, and no ante bet to lean on when the reels go quiet
Is Stones And Bones Worth Playing?
Character is what this one gets right. The art has a point of view, the symbol set was drawn with more care than a 2016 thirty-liner needed, and the triple-scatter arrangement gives the base game more to track than the format implies. It is pleasant to sit with, and it never asks for much.
The ceiling is the trouble, or rather the lack of one worth chasing. Genii never published a headline win figure for it, and it is not hard to see why: nothing is layered on top of the paytable to push a session past a good wild line. Anyone arriving from modern high-volatility releases will find it thin, and the free spins do little to change that impression. What is left is a good-looking, slow-moving line slot that pays in small pieces and never pretends otherwise.
