Bullshark Games goes bigger with the sequel — 7 reels, cluster pays, and a 20,000x max win ceiling on a scrapyard grid that rewards patience and punishes it in equal measure. We played the pre-release demo extensively before writing this review.

Junkyard Kings 2 earns its score through a combination of genuine mechanical ambition and specs that are hard to argue with. The step up to 7 reels over the original isn't cosmetic — a wider grid means cluster formation thresholds become achievable more frequently in both the base game and the bonus, and the 20,000x ceiling rewards those larger formations with proportionally higher win potential. We spent time in the pre-release demo before writing this, and the base game has enough going on between bonus triggers to stay engaging through cold streaks. The 96.29% RTP is above average for high volatility cluster pays, and the $0.10 minimum makes it accessible across all bankroll sizes. Bullshark Games have built on the first game's identity without losing what made it work.
Junkyard Kings 2 is Bullshark Games' follow-up to their original scrapyard cluster pays entry — and the sequel doesn't play it safe. Where the first game worked within a standard cluster grid, the sequel pushes to 7 reels, creating a wider playing field that fundamentally changes how clusters form and how frequently they reach the size thresholds that unlock the biggest multipliers. We played the pre-release demo ahead of the official casino launch and logged enough sessions to get a real read on how the base game runs and what the bonus round actually delivers when it hits well. At 96.29% RTP it sits above the average for high volatility slots in the cluster pays category, and the 20,000x max win ceiling is one of the highest you'll find at this volatility level.
Junkyard Kings 2 — base game, cluster pays on the 7-reel grid.
The junkyard theme is well-executed — rusted metal, scrap heaps, welding sparks, and a gritty industrial colour palette that sets it apart from the fantasy and mythology themes that dominate the genre. Bullshark commit to the aesthetic without letting it obscure the mechanics, and the result is a game that looks distinctive while playing with clarity. If you want to compare it against the wider cluster pays field, check the full slot RTP list — the 96.29% return holds up well against both genre peers and the broader high volatility market.
The move from the original's grid to 7 reels is the defining structural change in Junkyard Kings 2. On a wider grid, clusters can grow larger before they pay — and larger clusters in cluster pays mechanics typically apply more aggressive multipliers or unlock additional bonus states. In our pre-release demo sessions, we consistently saw clusters form across 4–6 symbol groups in the base game, with the 7th reel providing an additional column for cross-grid formations that would be impossible on a standard layout. The wider grid also means tumble mechanics (where winning symbols are removed and new ones fall in) have more room to create back-to-back cluster wins from a single spin.
Like most cluster pays slots, Junkyard Kings 2 uses a tumble (cascade) system — winning clusters are removed from the grid and replaced by new symbols falling from above. Each tumble within a single spin sequence can trigger new clusters, meaning a single paid spin can chain into multiple consecutive wins without additional cost. The 7-reel format extends the chain potential: more columns mean more positions where new symbols can land to complete adjacent clusters after a tumble clears space. In our demo testing, chains of 3–4 tumbles from a single spin were not rare, which is where the 20,000x ceiling starts to feel reachable rather than theoretical for players comparing against the slot picker criteria.
Junkyard Kings 2 runs a multiplier system tied to tumble count or cluster size — each successive tumble or qualifying large cluster within a spin sequence advances the multiplier, which applies to all subsequent wins in that sequence. In the base game, the multiplier resets between spins, but during the free spins bonus it carries over — meaning the longer the bonus runs, the higher the multiplier climbs. In our pre-release demo sessions, the multiplier compound effect during a well-loaded bonus round was the primary driver of the game's biggest theoretical wins. The 20,000x ceiling requires the multiplier to be deep and clusters to be large simultaneously, which is rare — but we saw early indicators in the demo that suggest it's structured to hit in the right conditions.
The bonus round is where Junkyard Kings 2 earns its 20,000x ceiling. Scatter lands trigger free spins with the multiplier in a persistent state — it doesn't reset between bonus spins, so every tumble chain advances the multiplier cumulatively across the entire feature. In our demo testing, mid-length bonus rounds with active multiplier climbs produced the most significant win outcomes. The 7-reel format means the bonus grid can simultaneously support multiple cluster formations per spin, making high-tumble spins particularly punishing to the game's math. As a high volatility title, the bonus doesn't trigger frequently — but when it does hit in a good state, the persistent multiplier structure gives it genuine upside.
Junkyard Kings 2 — free spins bonus with multiplier progression active.
We played Junkyard Kings 2 via the pre-release demo ahead of its official casino launch on April 29, 2026 — the same version that's available on this page now. Playing a game before it goes live at operators gives a different perspective than reviewing a title you've only seen on stream: you can control bet size, deliberately explore the edge cases of the mechanic, and run enough spins to form a genuine view of base game behaviour.
What stood out in the demo sessions was the base game pace. The 7-reel cluster format produces small wins frequently enough to give sessions structure, but the multiplier and large-cluster mechanics mean the game isn't paying out meaningful amounts consistently — it's accumulating toward moments. Between bonus triggers the game runs on the leaner side, which is exactly what you'd expect from a high volatility release targeting a 20,000x max win. The base game dry spells are manageable at $0.10 minimum bet, and the $50 maximum supports serious sessions where the 20,000x figure translates to a meaningful absolute number.
The bonus round behaved consistently with the specs across our demo runs. Multiplier progression during free spins was the core of every meaningful bonus outcome — modest multipliers produced modest results, and sessions where the multiplier climbed deep before large clusters formed produced the type of wins that explain the 20,000x ceiling. The full demo is available on this page so you can test the mechanic yourself before the game launches at your preferred casino. For context on how the RTP compares across the market, the slot RTP list has the full breakdown.
Yes — it earns an 8.2/10 from SlotArk. Based on our pre-release demo testing, the 7-reel cluster pays format delivers more formation potential than the original, and the persistent multiplier during free spins gives the bonus round genuine 20,000x ceiling credibility. The 96.29% RTP is solid for the volatility tier. If you're comfortable with high variance and want a cluster pays slot with a large max win, this is one of the better options in the category right now.
