What makes Bone Bonanza different

Released by BGaming on September 14, 2023, Bone Bonanza combines pay-anywhere wins with refilling symbols. Matching symbols do not need to follow a fixed payline. The total number of identical symbols on the screen determines the payout according to the paytable. Winning symbols then disappear, the remaining symbols fall, and replacements arrive from above.

A paid spin can therefore generate several consecutive wins before the board stops producing combinations. The official rules place no separate limit on the number of refills. That describes the continuation of a spin, not a promise of unlimited winnings: BGaming lists an overall maximum multiplier of 14,134x.

The published RTP is 96% and volatility is high. RTP describes a theoretical long-run return across a large number of wagers. It does not allocate 96% of a particular deposit back to its owner. For this game, the more useful practical distinction is between the ordinary refill sequence and the separate bonus progression that begins only after a Scatter trigger.

Scatters, refills and the bonus trigger

Four Scatters in the main game award 10 free spins. Five award 20, and six award 30. During the bonus, landing at least three Scatters in a spin adds five more free spins. Scatters can appear on any reel and have their own paytable treatment, separate from ordinary symbol counts.

The important feature is not simply the starting spin count. Free spins begin at level zero, and the game tracks which ordinary symbol types have already produced a win during that bonus. The first win from a previously uncollected low symbol raises the level by one. A previously uncollected high symbol raises it by two. The maximum level is 15.

This makes variety matter. Repeating a familiar winning symbol can still pay, but it does not keep earning the first-time level increase. The progress bar provides the visual record, so watching it explains more about the bonus than watching the free-spin counter alone. It is a record of this round's progress, not a player-controlled method for making a particular symbol arrive.

Multiplier symbols and my verdict

Multiplier symbols appear only during free spins and carry values from 2x to 100x, with the available multiplier determined by the level. When several multiplier symbols land in one spin, their values are added before the combined multiplier is applied to that spin's win. They are not multiplied together.

For example, multiplier symbols showing 2x and 5x make 7x. Applied to an eligible win of 3 units, that gives 21 units. This arithmetic illustrates the stated rule; it is not a prediction of how often those symbols or a matching win will occur.

Bone Bonanza also offers a free-spin purchase and a paid Chance x2 option. The purchase price changes with the selected bet. The rules describe Chance x2 as improving the chance of reaching free spins, while the two paid options cannot be active together. I would compare the displayed total cost before using either, rather than treat faster access as a stronger return.

My recommendation is for players who want a developing bonus with visible objectives and straightforward multiplier addition. The drawback is the high-volatility structure: an attractive progress bar does not guarantee a profitable round. Use the demo to learn which symbols advance levels, then set a cash and time limit before considering real-money play. BGaming supports browser play on desktop and mobile.
