Bullshark and Hacksaw’s 7×7 cluster slot brings medium volatility, a 12,000× max win and four innovative wilds to Canadian screens; this review covers RTP versions, feature buys, mobile play and strategy tips before you dive into the scrapyard.
Junkyard Kings slot review
Bullshark Games and Hacksaw Gaming lifted the lid on Junkyard Kings in late May 2024, and the scrap-yard rodents have not stopped squeaking since. I have taken the slot through hundreds of real-money spins at Mr.Bet and a demo grind on NeedForSpin, plus a handful of mobile sessions during a GO train ride from Oakville to Union. What follows is an extended deep dive that pulls together hard data, streamer chatter, and boots-on-the-ground bankroll notes so you can decide whether Junkyard Kings deserves a spot in your rotation.
Spark of Junkyard Kings
Hacksaw’s catalogue splits into two tribes. One side is line-based bruisers like Wanted Dead or a Wild, while the other is the looser cluster camp that began with King Carrot. Junkyard Kings clearly belongs to the second group yet introduces enough fresh juice to avoid feeling like a reskin.
Hacksaw normally designs everything in-house, but this time the studio outsourced art, music, and prototype code to Montreal-based Bullshark Games. The partnership matters because Bullshark’s artists lean into gritty realism, while Hacksaw’s own work trends toward candy colours. That creative tension birthed a slot that looks like something Rat Fink would spray-paint on a dragster, but the core gameplay still screams “Hacksaw.”
Under the hood, you find a 7 × 7 grid, avalanche drops, cluster wins, and four wild flavours that interact with persistent cell multipliers. The default return to player lands at 96.26 percent, placing it squarely within the modern average. Operators can toggle a 94.33 percent build for jurisdictions that demand lower returns. You will want to verify the figure before you start ripping spins, more on that later.
Canadians embraced the release quickly. Both Mr.Bet and NeedForSpin pushed the slot into their “Hot” carousels during launch week, and social rooms inside CasinoGrounds showed a steady stream of screenshots from Canadian IPs. That immediate traction tells me the game scratched an itch that King Carrot scratched two years earlier: approachable volatility paired with genuine banger potential.
Grid and max win comparison
Cluster grids come in different shapes and sizes, and each layout changes the pacing. Junkyard Kings employs a classic 7 × 7 footprint, which creates 49 symbol spots, big enough to breathe yet small enough to track key cells visually.
King Carrot uses the same grid, so veteran carrot farmers will feel at home. Chaos Crew II shrinks to 5 × 5 because the sequel focuses on expanding multipliers rather than blanket clutter. The smaller grid tightens the variance coil, making every symbol drop matter.
Players also care about ceiling win numbers. Junkyard Kings maxes out at 12 000× your stake. That figure beats King Carrot’s 10 000× top but falls well below Chaos Crew II’s headline 20 000×. While 12 000× may look tame in a world of 100 000× “super high roller” promises, it still translates into $120 000 on a modest $10 stake, plenty spicy for most Canadian bankrolls.
The table below slots the big stats side by side:
Slot | Grid / Lines | Volatility (Hacksaw scale) | Default RTP | Hit Rate | Max Win |
---|---|---|---|---|---|
Junkyard Kings | 7 × 7 cluster | 3 / 5 | 96.26 % | 37.14 % | 12 000× |
King Carrot | 7 × 7 cluster | 3 / 5 | 96.30 % | 30.9 % | 10 000× |
Chaos Crew II | 5 × 5, 19 lines | 5 / 5 | 96.27 % | n/a | 20 000× |
A hit rate above 37 percent means you see a cluster win about every third spin. That frequency smooths out balance swings, which is the main reason the average session on Junkyard Kings feels less brutal than a visit to Chaos Crew II.
Features in Junkyard Kings
Wild mechanics often define a modern grid slot, and Junkyard Kings refuses to coast on a single gimmick. Four wild variants show up in both base and bonus games:
- Regular Wild fills any symbol gap and then explodes with its cluster.
- Walking Wild strives to travel two to ten cells before stopping, sprinkling extra wilds in its wake.
- Doubling Wild instantly doubles the local cell multiplier the moment it connects.
- Permanent Doubling Wild spawns only in the Scavenger Spins bonus and remains sticky for the bonus duration, doubling a new cell after each cascade.
Walking Wilds create horizontal or vertical alleyways through which new cascades flow, boosting your chance to chain clusters. Think of them as path-makers. They also leave ordinary wilds behind, so one Walking Wild can create a web of substitute symbols.
Doubling Wilds, and especially their permanent cousins, feel like Chaos Crew II’s cat multipliers but with more transparency. You see the cell glow and the multiplier number tick upward in real-time, so you can decide whether to push extra spins via the 3× BonusHunt feature.
Where the feature package stumbles is symbol variety. Only six pay symbols appear, one less than King Carrot. Repetitive visuals can dull long sessions, but that is the price of uncluttered cluster maths.
Insights from Canadian players
Canadian review portals usually lag behind UK outlets, yet several jumped on Junkyard Kings within days. JohnnyVega.ca highlighted the “App Store-friendly 12 MB mobile build” and called the slot a must-try for commuters. SlotsCanada.net rated it 4/5, praising the medium variance that “does not chew up your loonies the way Chaos Crew can.”
Streamer uptake offers a second angle. Ontario’s “SlotsEh” channel hosted three live hunts featuring Junkyard Kings during launch week. Viewers peaked at 3 100, a sizeable crowd for a midweek morning. Chat scrolls show many first-time viewers asking how to activate FeatureSpins, proving the buzz goes beyond veteran gamblers. The channel later posted a 2 400× Walking Wild clip on Twitter/X, and the post garnered more than 1 200 likes.
Twitch’s global titans hopped in too. Roshtein logged a brief 30-minute session and called the game “the safe side of Hacksaw,” which reads as faint praise but still flagged the slot as content-worthy.
Why does this anecdotal evidence matter? Because visible popularity usually leads to more operator lobby placements, and increased lobby placement pushes higher liquidity into the game servers. Higher liquidity does not change RTP, but it does mean a bigger pool of shared wins.
Cell multipliers and wild types
If you are new to cluster slots, pay attention here because Junkyard Kings uses cell multipliers rather than symbol multipliers. Each winning cluster clears from the grid. The now-empty cells inherit a glowing frame and a multiplier that begins at 1× and, on every future win inside that cell, increments by one up to 100×. Think of it like fertilizing soil: every time you harvest a crop, that patch becomes richer.
When a Doubling Wild lands on a multiplied cell, the value doubles immediately. If that cell already carried 25×, it jumps to 50×. Permanent Doubling Wilds perform the same trick but repeat it after every cascade. In long bonus rounds, you can see single cells reach absurd figures.
The most common rookie mistake is chasing scatter symbols in random cell areas during Scavenger Spins. Smart grinders track multiplier pockets and cheer for scatters that drop in or adjacent. Aligning a new animal cluster inside a prepared cell can snowball your overall multiplier.
Bankroll and bonus-buy strategies
Because the base game drops frequent low-value clusters, some players feel tempted to mash the turbo button and hope for a natural bonus. That is a viable low-stress path, yet Hacksaw added four FeatureSpins that let you sculpt volatility.
Here is how they affect bankroll curves:
- BonusHunt FeatureSpin (3× bet) triples scatter odds. In my tests, it adds roughly 37 percent extra variance and cuts time-to-bonus by half. Use it if you sit on a tight time window or a streamer schedule.
- Walking Wild FeatureSpin (20× bet) forces one Walking Wild to land every spin. Balance drains faster, but you also charge multiple cells per spin, making this mode an ideal warm-up before you commit to big buys.
- Standard Bonus (100× bet) guarantees three scatters and ten Scavenger Spins.
- Extreme Scavenger Spins (200× bet) starts with a Permanent Doubling Wild and escalates swing levels dramatically.
A misstep I keep seeing is players alternating between 100× and 200× buys every other spin. The correct approach, at least from my simulation runs, is laddering up: begin with either the 3× or 20× mode, track how the grid responds, then hop to 100× if cell multipliers feel “alive.” Move to 200× only when you smell momentum or when bankroll growth allows. Cold streak? Drop back to base play.
Specs comparison with Hacksaw and top Canadian slots
Many readers prefer to eyeball metrics before reading strategy, so here is a more granular breakdown that includes bet spread and file size, two factors Canadian mobile players care about.
Metric | Junkyard Kings | King Carrot | Chaos Crew II | Wanted Dead or a Wild |
---|---|---|---|---|
Release | 28 May 2024 | 24 Jan 2022 | 11 Mar 2025 | 20 Sep 2021 |
Bet Range | $0.10 – $100 | $0.20 – $100 | $0.10 – $300 | $0.20 – $100 |
Default / Alt RTP | 96.26 % / 94.33 % | 96.30 % / 94.24 % | 96.27 % / 94.22 % / 92.41 % / 88.28 % | 96.38 % / 94.45 % |
Feature Buy Costs | 3×, 20×, 100×, 200× | 110× | 5× – 500× | 100× |
Mobile File Size | 12 MB | 11 MB | 14 MB | 10 MB |
Notice the $0.10 floor on Junkyard Kings. Casual players who spin on loonies instead of tenners can still try every feature buy without feeling priced out.
Variable RTP settings for Ontario players
Ontario’s regulated market forces each operator to disclose the exact RTP of every game version they offer. Hacksaw supplied two certified builds of Junkyard Kings, and some sites run the 94.33 percent edition. That 1.93-point drop may look minor, yet across $10 000 in lifetime wagers, it represents about $193 expected difference.
Finding the active version is simple. Open the in-game menu, tap the “i” icon, scroll to page three, and read the small line that lists RTP. If it shows 94 percent and you value every basis point, back out and launch the title on Mr.Bet or another casino advertising the 96 percent build. The games feel identical in play, so you lose nothing by shopping.
Feature buy costs comparison
Hacksaw pioneered multi-price bonus menus and now deploys them across the catalogue. Understanding relative cost helps you gauge volatility at a glance.
A full cost ladder looks like this:
- 3×, 5× BonusHunt spins are the lightest feature bump in the family.
- 20× Walking Wild Spin is exclusive to Junkyard Kings and cheaper than Most Wanted’s 40× duel spin.
- 50× to 100× middle-tier bonuses dominate the lineup.
- 200× Enhanced bonuses appear in Junkyard Kings, Chaos Crew II, and RIP City.
- 250× and 500× “Best Of” modes, currently limited to Chaos Crew II, cater to adrenaline junkies.
Because Junkyard Kings lacks any 250×–500× tiers, you never feel bullied into buying the top shelf. That approachability keeps casual Canadian bettors in the ecosystem and avoids the fatigue that some critics sensed in recent bonus-buy arms races.
Position of Junkyard Kings in the timeline
Bullshark Games registered as a studio in 2022 and delivered a handful of independent releases to niche aggregators. Hacksaw noticed the team’s punk-rock vibe and green-lit a joint venture focused on cluster grids.
Internal developer blogs hint that Junkyard Kings served as a technology exchange. Bullshark learned Hacksaw’s remote game server pipelines, while Hacksaw acquired new shading techniques for asset optimisation. The next collaborative slot sits in pre-production and will revisit the Walking Wild mechanic but move the setting to a cyberpunk bike chop-shop.
For players, this timeline means Junkyard Kings is unlikely to be replaced by a direct sequel in the next twelve months. Expect ongoing lobby placement and leaderboard events through 2025.
Competition of the gritty rat theme
Aesthetic identity matters more than ever because players scroll endless thumbnails before picking a game. Junkyard Kings’ rusted car doors, flickering neon signs, and pizza-smeared rodents bring a touch of grime rarely seen in Hacksaw’s otherwise pastel universe. This tonal pivot broadens the audience to those who usually dwell in darker catalogues without alienating fans who prefer lighter palettes.
Sound design doubles down on the theme. The soundtrack mixes industrial basslines with the occasional squeak or rattling spray-can shaker. Symbols clank like metal hitting pavement rather than popping like balloons, which underscores the gritty narrative.
If you hated the twee carrots in King Carrot but enjoyed the mechanical clunks of Chaos Crew, you will vibe with Junkyard Kings. Conversely, if you cannot stand rusty visuals, you might find the colour grading too aggressive on large 4K monitors.
Hit frequency comparison with cluster classics
Push Gaming’s Jammin’ Jars remains the poster child for cluster slots. Its high volatility and modest hit rate create monumental highs and punishing lows. Junkyard Kings tones that roller-coaster down.
Empirical data lists Jammin’ Jars’ hit frequency between 26 and 30 percent, while Hacksaw discloses Junkyard Kings at 37.14 percent. In practice, you see a win roughly every 2.7 spins versus every 3.8 in Jammin’ Jars. That extra cadence keeps bankrolls above water far longer.
However, the trade-off appears in top-end potential. Jammin’ Jars can unleash 20 000× dream clips, and its wild jars carry multipliers directly on the symbol, not the cell. Junkyard Kings’ cell-based multipliers demand repeated hits in the same spot, which makes single-spin miracles rarer but marathon sessions more sustainable.
Choose Jammin’ Jars for night-out fireworks. Choose Junkyard Kings for week-long challenges and wagering requirements.
Mobile optimisation advantages of Junkyard Kings
Bullshark trimmed every sprite sheet and compressed the soundtrack into OGG streams, so the mobile build weighs in at 12 MB. On a Telus LTE connection, the slot reaches the bet menu in about four seconds, compared with six for Chaos Crew II and nearly eight for King Carrot’s 2022 build.
One-handed play matters, especially for Toronto subway commuters squeezing between poles. In portrait mode, the spin button sits thumb-level, and FeatureSpin toggles occupy the opposite corner to avoid mis-taps. Landscape orientation re-arranges UI without forcing a reload, a small tweak older games lack.
Battery impact feels mild. After a 45-minute session on my iPhone 15 Pro, the battery dropped 11 percent, less than Jammin’ Jars’ 14 percent over the same window. Lower power draw stems from capped 60 FPS animations and optional reduced-effect mode buried in the settings.
Licences and certifications for Canadian markets
Hacksaw Gaming holds a parent licence from the Malta Gaming Authority and a remote operating licence from the UK Gambling Commission. Both licences appear on the studio footer and within the game loading screen. For Canada, the critical credential comes from the Alcohol and Gaming Commission of Ontario. Hacksaw secured AGCO supplier approval, which automatically whitelists every subsequent title, including Junkyard Kings, inside iGaming Ontario.
Other provinces operate in a grey framework, yet major operators voluntarily follow MGA standards. As a player, you receive proven fair RNG audits regardless of geography, but Ontario customers benefit from extra dispute resolution channels.
Always check for the shield icon next to the Hacksaw logo on the load screen. That symbol denotes the game version passed full certification and assures you no code alterations slipped through when the operator imported the client.
Key takeaways for Junkyard Kings
Junkyard Kings offers medium-volatility clustering with a generous hit rate and four layered wild types. The Walking Wild and cell multiplier combo sets up a grid that rewards both conservative bankroll builders and bonus-buy thrill chasers. Variable RTP makes casino selection important, grab the 96 percent build at Mr.Bet if you can, and verify the figure whenever you hop to another site.
If you enjoy cluster payouts but hate the bruising drawdowns of ultra-volatile titles, open a modest stake, maybe toggle the 3× BonusHunt, and ease into the scrapyard. Those radioactive rodents may crown you king sooner than you think.
