A 6x5 pay-anywhere Day of the Dead slot where a level bar, fed by wins on new symbols, raises the free-spin multipliers from x2 up to x100.

Our #1 pick to play for real
Bone Bonanza at YEET
10% weekly lossback
7/10
For a bonus chaser, yes; for someone who mostly spins the main game, no. The free spins have a level bar that climbs when you win with symbols you have not yet won with, and higher levels mean higher multipliers, so the round gives you something to follow. The drawback is that it needs wins to work: multipliers exist only in the free spins, and BGaming puts a natural trigger at about 1 in 332.
Who it suits
Play this if…
- Bonus chasers: a round has a level to climb, not just spins to wait through
- Bonus buyers: the buy gives up nothing in RTP against spinning
- You like variety in your wins: new symbols are what lift the bar
Skip this if…
- Short-session players: multipliers do not exist in the main game
- Players who want big values early: the bar has to be raised first
- Anyone who dislikes dry bonuses: most of our bought free spins paid nothing

Bone Bonanza: Full Review
Bone Bonanza adds a level bar to BGaming's pay-anywhere free-spins formula: the wider the mix of symbols you win with during a round, the bigger the multipliers that can land on later spins. BGaming released this Day of the Dead game in September 2023 as part of its Bonanza series. It suits players who want a bonus with a job to do, more than short-session players.

How Bone Bonanza works
Eight or more matching symbols anywhere on the grid pay, in three bands, and refills continue with no limit until no new win forms.
| Symbol | 12 or more | 10 or 11 | 8 or 9 |
|---|---|---|---|
| Green skull | $50.00 | $25.00 | $10.00 |
| Bottle | $25.00 | $10.00 | $2.50 |
| Sun | $15.00 | $5.00 | $2.00 |
| Maracas | $12.00 | $2.00 | $1.50 |
| Green gem | $10.00 | $1.50 | $1.00 |
| Red gem | $8.00 | $1.20 | $0.80 |
| Orange gem | $5.00 | $1.00 | $0.50 |

| Pink gem | $2.00 | $0.75 | $0.25 |

Multipliers belong to the free spins alone, so a main-game spin is worth its paytable value and nothing more.

How the Bone Bonanza level bar works
The level bar is what separates this game from the rest of the Bonanza family. It starts at 0 and tops out at 15 for each round of free spins. A win on a low symbol you have not yet won with this round adds one level, and a win on a high symbol you have not yet won with adds two.
Multiplier symbols appear only in the free spins, each holding a value from x2 to x100, and the level bar decides how high those values run. Several on one spin are added together and applied to that spin's win. On our free spin 9, wins of $1.60 met a x10 symbol, and the spin paid $16.00.
Free spin 9 of our bought round, as the x10 applies to 1.60. FluxPlays demo test, 9 November 2026.
In practice the round rewards variety. By the rules, a run of wins on the same symbol does nothing for the bar, so a spin that adds a new symbol to your list matters more than its payout suggests.
The same spin once the multiplier has applied: 16.00. FluxPlays demo test, 9 November 2026.
Bone Bonanza free spins: how they trigger
Four or more Scatters anywhere start the round and pay on their own.
| Scatters | Free spins | Scatter pay at $1 |
|---|---|---|
| 4 | 10 | $3.00 |
| 5 | 20 | $5.00 |
| 6 | 30 | $100.00 |
A further three Scatters in the round bring five extra spins. BGaming puts a natural trigger at about 1 in 332, so the main game can run a long time before you see the bar move at all.
Bonus buy and Chance x2: prices and what you get
The buy starts the free spins at once, and Chance x2 adds a quarter to the bet for more chances of Scatters. The two cannot be combined.

For us the buy is the sensible way to judge this game, because the level bar is the whole idea and it only exists inside the round.
RTP, volatility and max win
The base game, the buy and Chance x2 all return 96% by the rules. BGaming labels the volatility High. The game's intro screen and BGaming's page give a maximum win of 14,134x the bet, while the rules text does not repeat the figure.

Tested on BGaming's public fun-mode demo (rule version 1.0, July 2023, game version 1.0.0) on 9 November 2026, with FUN practice credits read here as dollars, from a 1,000.00 balance. The demo opened at 0.20 and was raised to 1.00 for all 100 base spins. Chance x2 ran for 10 spins at 1.25 each and the Buy Bonus was played once. Spins were started with a Space key press and the game's frame timer was driven by a script; game logic and server calls were untouched. Session: $212.50 staked, $83.00 back, ending at 870.50 by arithmetic from the server log.
Our bought round was a lean one, and it shows why the level bar needs wins to work with. Eight of the ten free spins paid nothing, so there was little for the bar to feed on, and the best multiplier we saw was x10. The round's value came from two spins, the x10 above and a $4.50 hit earlier on.
Natural free spins stayed away across 110 paid spins, with three Scatters landing twice, so the trigger is described by the rules and we cannot say which level the round reached. The main game paid in small pieces: 36 winning spins, and a losing run of 18 ending on spin 49. Chance x2 had one good spin of $11.00.
The end of our bought round: ten free spins, no retrigger. FluxPlays demo test, 9 November 2026.
One short session is enough to learn how the bar behaves, but it says nothing useful about the return.
Is Bone Bonanza worth playing?
For a bonus chaser who wants more to do than watch, yes; for anyone who mostly spins the main game, no. The level bar gives the free spins a small plan, and the multipliers have room to grow to x100, but they need a run of varied wins to get there and our session showed how quickly a round can stall.
Pick Bonanza Billion if you want the full multiplier range available from the first free spin. Pick Bone Bonanza if a round that climbs toward bigger values appeals more than one that can pay at any moment.
Try it in the demo with one bought round and keep an eye on the numbers beside the board. Seeing the bar move tells you straight away whether this variation is for you.
Frequently Asked Questions
How does the level bar work in Bone Bonanza?+
It runs only during the free spins, from 0 up to 15. A win on a low symbol not yet won with that round adds one level, and a high symbol adds two. Higher levels mean higher multipliers, up to x100.
How do you trigger free spins in Bone Bonanza?+
Four, five or six Scatters give 10, 20 or 30 free spins, and they pay as well. Three or more during the round add five more spins. BGaming puts the natural trigger at about 1 in 332, and we got none across our paid spins.
Can you buy the bonus in Bone Bonanza, and what does it cost?+
Yes, Buy Bonus costs 100x the bet at the same 96% RTP as normal play. Chance x2 is the cheaper option: it adds a quarter to the bet for more chances of free spins, and it switches the buy off while it is active.
What is the max win in Bone Bonanza?+
It is 14,134x the bet, shown on the game's intro screen and on BGaming's page. Getting close needs the free spins at a high level, with big multiplier values landing on a good win.
