Buster’s Bones makes the same special symbols serve two purposes. When Buster appears with at least one bone, he dashes around the grid, turns bones into Wilds and adds their values to a collar multiplier. If he joins a Cluster win, that multiplier enhances the result. The feature is temporary in the main game—Buster leaves on the next spin—but Free Spins keep him on the reels and let him continue collecting. The 6×6 layout is therefore about collecting and converting objects within a cluster system, not paylines or a conventional Scatter ladder.

Buster converts bones into Wilds and a cluster multiplier
The game uses a six-reel, six-row grid and Cluster wins; the official record provides no line or ways count. Buster’s Bones activates when the Buster special symbol appears with at least one bone special symbol. He dashes around, collecting the bones and turning each into a Wild that substitutes for paying symbols. Buster also acts as a Wild after collecting all bones. Their values are tallied into a win multiplier, which enhances a payout only if Buster participates in a Cluster win. So collection alone does not establish a win: the multiplier must be connected to a qualifying cluster involving Buster.
Buster disappears on the next spin, taking his multiplier with him, although he may return randomly. Random Features can place bones and Buster as reels spin; if he arrives with at least one bone, the same collection feature activates. This is a short-lived state in the base game, not a banked multiplier that carries indefinitely. The source does not specify the bone values or the formula for combining them, so the review avoids assigning a numerical multiplier from a particular collection. The meaningful rule is the sequence: collect, convert, tally, and apply if Buster joins a cluster.
Free Spins preserve Buster’s presence
Two Free Spins Scatters together with one Buster symbol award eight Free Spins. In the bonus, Buster remains on the reels for the entire round, jumping around to collect bones and build a multiplier that resets only when the Bonus Round ends. One or two Free Spins Scatters during the feature award one or three additional spins, respectively. The source does not explain whether the Buster multiplier uses exactly the same payout condition as the base feature, so it is safest to state only that the multiplier accumulates and persists until the feature ends.
This retention changes the core interaction. In the main game, each Buster appearance is a self-contained event and he leaves before the next spin; in Free Spins, the same character remains present so the collection can continue across the bonus. The paired trigger also requires both Scatter symbols and Buster, rather than a Scatter count alone. The feature’s Buy option is priced at 60× the original wager, but the purchase detail does not make the normal trigger more likely or provide probability information. The exact result still depends on bone collection and the feature’s cluster conditions.
Reference figures
The official catalog lists RTP 96.07%, volatility 6.5 and a maximum payout of 900× bet for this exact title. Operator settings may differ. No maximum-win probability, bone-value table or collection multiplier formula is supplied. The 900× ceiling and volatility label therefore cannot be used to estimate how often Buster collects enough bones or participates in a valuable Cluster win.
Strengths and weak points
Strengths
Bone symbols have a direct two-part use: they become Wilds and contribute to Buster’s multiplier. Free Spins change the timing by keeping him present for continued collection.
Weaknesses
Bone values and the multiplier calculation are not provided, and the cluster record has no line count. Buster’s base-game multiplier also leaves with him on the next spin.
Our Editor’s View
Buster’s Bones gives its central character a clear mechanical job: bones become Wilds, their values create a multiplier, and Buster must join a Cluster win for that multiplier to matter. The contrast between a one-spin base-game visit and persistent presence through Free Spins creates a meaningful mode change without introducing an unrelated bonus system. The limitation is that several calculation details remain absent, including bone values and the precise multiplier formula, while the cluster rules do not state a line count. Players who enjoy tracking symbol collection into a cluster payout should find a coherent feature loop; those who want transparent arithmetic for each collected object will need more detail than this record provides. Its modest catalog ceiling is best read as a cap, not as evidence about how frequently the collection sequence pays. Related review: Barn Busters’ animal-themed grid.
