Unlocking Rows & X-Unlock
The mechanical core: rows open progressively as the right symbols land, expanding the grid mid-session instead of staying fixed at 4x5.
Buffalo Prime X-Unlock Running Wins is a buffalo-themed slot from Fugaso, built on a 4x5 grid with 20 paylines and a row-unlocking mechanic the studio calls X-Unlock. Buffalo Prime X-Unlock stacks six bonus features on that base, from a coin-collecting Running Wins Bonus to a Royal Jackpot worth x10,000 the bet, plus a confirmed Bonus Buy option. This review covers every confirmed mechanic and whether it's worth your time at the tables.

Buffalo Prime X-Unlock runs on a 4x5 grid with 20 paylines, which is the frame everything else in this review sits inside. Land three or more matching symbols across an active line and you're paid the base game rate; the twist is that not every row is live from spin one.
Rows start locked and open through the X-Unlock feature as specific symbols land, so the number of paying positions grows across a session instead of sitting fixed at the full grid every spin. It's a structural difference from a standard fixed-reel buffalo slot, and it's the mechanic the rest of this review keeps coming back to.
That structure changes how a session feels more than it changes the base math. Early spins carry less of the grid, later ones carry more, and the jackpot panel is the visible tracker of that progress. We'd rather describe it accurately than smooth it into generic "exciting bonus features" copy, because the row-unlocking pace is the actual thing worth knowing before you play.
The 20 paylines themselves are fixed, so what the X-Unlock feature actually changes is how much of the grid those paylines can draw from at any given moment, not the payline count itself. That's a subtle but real distinction worth keeping straight before you start comparing this against other buffalo titles.
The X-Unlock feature is Fugaso's name for the row-unlocking system that separates Buffalo Prime from a standard buffalo-theme slot. Locked rows sit dormant on the grid until triggered open, and every row that unlocks feeds directly into the Running Wins Bonus.
Running Wins is the coin-collection layer riding on top of the X-Unlock feature. Coin and money symbols carry their own value shown right on the reel - the official art shows one example worth 5.00 - and collecting them is how progress toward the Running Wins Jackpots actually happens. Land enough, in the right combination, and you're in range of the six-tier ladder that tops out at the Royal Jackpot.
Lucky Riches rounds out the mechanic as Fugaso's dedicated cash-prize mode layered on the same collection system, and Free Spins gives the whole thing a separate round to run in without touching your balance per spin. The full trigger conditions and unlock sequencing get the deep-dive treatment in our step-by-step feature guide.
What makes this worth calling out in a review, rather than just a feature list: most buffalo slots run a flat reel set with a bonus round bolted on. This one ties its bonus round directly to the base game's own structure, so the two aren't really separate systems. That's a design choice, not marketing language, and it's the reason we keep pointing back to the X-Unlock feature across this whole review.
Three symbol tiers make up the paytable here: card-rank fillers at the bottom, a wildlife cast in the middle, and jackpot coin symbols layered over the top. The buffalo itself is the highest-paying regular symbol on the reels.
Expect eagle, wolf and elk alongside 10-through-Ace cards for the standard set, all set against Fugaso's sunset-prairie backdrop. The six jackpot coins mirror the Running Wins ladder one-for-one, Mini through Royal, and each carries a cash value printed directly on the coin rather than a flat multiplier.
Exact per-symbol payout multipliers for the card and wildlife tiers aren't listed here, we're not inventing numbers Fugaso hasn't put in the paytable. What's confirmed is the hierarchy: cards pay least, wildlife pays more, buffalo pays most among regular symbols, and the coins sit in their own separate jackpot-linked category entirely.
The feature set breaks into three practical clusters: the row-unlocking engine (X-Unlock and Unlocking Rows), the payout layer riding on top of it (Running Wins Bonus, Running Wins Jackpots, Royal Jackpot), and the two extras that give the base game breathing room (Free Spins, Lucky Riches). None of them work in isolation. Trigger one and you're usually feeding into the next.

Coin symbols collect toward a six-tier ladder - Mini, Minor, Midi, Major, Grand, Royal - each a fixed multiplier of your bet.

Available. Pay 100x your stake to buy straight into the feature round.
Read top to bottom, the roster tells a coherent story: unlock the grid, collect coins, cash in a jackpot tier, and use Free Spins or Lucky Riches to stretch that process further before your balance takes another hit. Bonus Buy is the only feature here that sits outside that chain, since it just lets you enter it directly.
Official RTP is 96.20%, volatility rating is High. In practice that means smaller wins turn up often, while the higher-value collector and jackpot hits are spaced further apart. The game's overall max win, distinct from the Royal Jackpot's own x10,000 ceiling, is 15,000x the bet.
That last distinction matters: the Royal Jackpot multiplier and the game's total max win aren't automatically the same number, since max win usually accounts for stacked features (Free Spins plus Running Wins plus a jackpot hit) rather than one ladder tier alone.
Match your bet size to the High rating rather than the table minimum - it matters more on a row-unlocking slot like this than on a flat-paying one, since the payout structure shifts as rows open.
It runs on Fugaso's HTML5 engine, so it plays in a mobile browser without a download on phone or tablet. Fugaso's asset set includes dedicated portrait layouts for the main interface and the bonus screens, which usually means the mobile build isn't just a shrunk desktop view.
The 4x5 grid, jackpot panel and bet controls all carry over to touch, with autoplay and quick-bet options sized for thumbs rather than a mouse.
This slot's row-unlocking structure means a session can feel slow in the base game and then open up fast once rows start unlocking. Plan your bankroll around that swing rather than a flat per-spin budget.
Size your bet against your total bankroll rather than the table minimum, using the High rating and the $0.10-$20 range as your guide. A six-tier jackpot ladder rewards patience more than it rewards chasing every spin at max bet. If Bonus Buy at 100x your stake fits your budget, it's a faster way to see the Running Wins mechanic in action without waiting for a natural trigger.
Set a session length before you start, not just a loss limit. Because the X-Unlock feature's progress can reset between sessions, cutting a session short right as rows are opening is the single most common regret we hear about row-unlocking slots in general.

Fugaso already has other frontier-themed titles in its catalog, including Power Boost Buffalo Express, so it's worth placing this one against the genre rather than reviewing it in a vacuum. The row-unlocking mechanic is the clearest point of difference from a standard buffalo slot.
| Feature | Buffalo Prime X-Unlock | Typical Buffalo-Theme Slot |
|---|---|---|
| Grid | 4x5, rows unlock progressively | Fixed grid from spin one |
| Jackpot structure | Six-tier ladder, Mini to Royal, up to x10,000 | Usually one or two jackpot tiers |
| Bonus Buy | Available | Varies by title, often absent |
| Coin/collect mechanic | Running Wins coin values shown on-reel | Usually multiplier-only, no on-reel cash value |
Power Boost Buffalo Express is Fugaso's other frontier-themed title, but it runs a standard fixed grid without the row-unlocking twist or the six-tier ladder that defines this release.
The genre comparison holds regardless: a six-tier jackpot ladder with an on-reel coin value and a progressive row-unlock is a more involved structure than most buffalo slots run. Whether that translates to better real-world returns depends on the RTP and volatility figures above.
Buffalo Prime X-Unlock itself isn't licensed by ACMA or any other regulator - the casino you play it at is. Fugaso builds its games to the certification standards its casino partners require, but legality in your market comes down to whether the operator holds a license your regulator recognizes.
