Skeletons, moats and a jaunty tune
Bird’s-eye view of a fortress ringed by a moat, walls and cracked earth, with four differently coloured skeletons grinning up at the camera. Nothing here is remotely spooky, and the art sits closer to a Saturday morning cartoon than a tomb-raiding horror. The soundtrack is a jaunty adventure tune that swells on wins and triggers, and the bonus drops the camera indoors into a stone-encrusted chamber.
How does the Bone Raiders Slot Demo play?
Bone Raiders plays on five reels and three rows with 243 ways to win. Wins pay through a Pay Ways mechanic: identical symbols on adjacent reels starting from the leftmost reel, so there are no fixed paylines to follow. Bets run from €0.10 to €100 per spin, and the demo uses the same 96.1% base game RTP, medium to high volatility and 10,000x maximum win as real money play.
Eight regular symbols carry the pay table. The four card suits are close to decorative at 0.3x the bet for five of a kind, while the four skeleton characters pay from 10x up to 100x for five. No wilds appear in the base game, so ordinary symbol hits do the work until the multiplier gets involved.
What the respins and the coin grid actually do
Any winning combination triggers a respin, and the detail worth knowing is that every symbol drops away for it, not just the non-winners. Win again and the multiplier doubles. Keep winning and it keeps doubling, until a respin comes back blank and the sequence ends, resetting to x1 on your next fresh spin. It rewards a particular kind of luck: not one enormous hit, but three or four modest ones back to back.
Three scatters on reels 2, 3 and 4 open the bonus, and the play area changes shape completely. You get a 7x7 grid with only the centre 3x3 active, the remaining cells sitting as blockers that must be destroyed before they can hold symbols. The triggering scatters convert into feature symbols, each with its own targeting pattern: the Magic Staff hits one symbol 3 to 7 times, the Bomb explodes an area from 3x3 up to 7x7 around itself, the Cannon blasts one or several random areas, and the Compass takes out rows, columns, diagonals or combinations of those. Targeted blockers become active cells. Targeted coins have their value doubled. After acting, a feature symbol turns into a coin worth 1x the bet, so it keeps contributing to the total.
You begin with two spins, which is tight. Each new feature symbol resets the count, and every 20 blockers destroyed raises the reset value by +1, capped at four. That cap is the ceiling on how comfortable this feature ever becomes, and a bonus that opens with two blanks is over before the chamber has finished loading.
⚠️ Worth Knowing: The feature buy costs 70x your bet and carries a higher 96.5% RTP, but it is not available in the demo. Whatever you learn about the coin grid in free play, you learn by triggering it the slow way.

What are the best casinos for Bone Raiders?
Relax Gaming distributes widely, so the useful question is not who stocks the game but what surrounds it. Our Relax Gaming casinos list covers sites carrying the studio’s library, with licensing and payment details laid out per operator.
Stake flexibility helps here: a €0.10 floor suits small sessions, and the €100 ceiling is high enough that bet caps on bonus funds are worth checking first. The casino bonus types hub sets out which offer categories are worth comparing before you deposit, particularly if you plan to use the 70x buy.
Play the Bone Raiders Slot Demo for free
The demo above runs the base game and the bonus round at any stake in the range, so a few hundred spins will tell you what the respin chains really deliver. Most of them end after one extra spin. The ones that do not are where the session lives.
Running the Bone Raiders slot demo is also the honest way to find out whether the two-spin bonus opening irritates you before real money is involved, since that first pair of spins decides most of what follows.
💡 Tip: In free play, track how far your respin chains get. Counting how often a sequence reaches x4 or better tells you more about your likely session than the 10,000x headline does.
Pros and cons
| ✅ Pros | ❌ Cons |
|---|
| Rising respin multiplier keeps the base game active | Only two starting spins in the bonus |
| Expanding grid with coin doubling and blocker destruction | Feature buy locked out of free play |
| Charming, polished cartoon presentation | Card suits pay just 0.3x for five |
| Wide €0.10 to €100 bet range | No wilds in the base game |
Verdict
- The respin chain with its doubling multiplier is the standout, and it makes low-value hits worth watching.
- The coin grid is genuinely tactical, but its two-spin start means a slow first blocker clear ends the feature fast.
- At medium to high volatility, 10,000x is a distant target rather than a realistic session goal.
Best for: players who want a base game that does something between bonuses, and who like the cute Relax Gaming house style.
Skip if: you need frequent bonus entries, or you want the buy option available before committing cash.
Set your limits before switching from free play to real money, and stop when you reach them.
