X-Unlock
The row-unlocking engine that expands the grid mid-session.
Buffalo Prime X-Unlock Running Wins is Fugaso's new buffalo-themed slot, built around a row-unlocking mechanic called X-Unlock and a coin-collecting Running Wins Bonus. Buffalo Prime X-Unlock plays out on a 4x5 grid across 20 paylines, backed by a six-tier jackpot ladder that tops out at the Royal Jackpot's x10,000 multiplier.

Buffalo Prime X-Unlock is Fugaso's take on the buffalo-and-prairie slot genre, built around a mechanic the studio calls X-Unlock. Instead of every row paying from the first spin, it locks part of its grid and opens it up as you play, tying that progression directly to the Running Wins Bonus and its six-tier jackpot ladder.
The theme leans into open-plains Americana: buffalo herds, sunset skies, and a wildlife cast that includes eagles, wolves and elk alongside card-rank fillers. Fugaso positions it as a follow-up to its earlier buffalo titles, but the row-unlocking system and the six-way jackpot split are new to this release.
Buffalo Prime X-Unlock is live now, with Fugaso listing 2026-07-30 as the game's release date. You can play it today at our partner casinos, Slotimo and Blitz-bet.
This page is the hub for everything about it: mechanics, the jackpot ladder, and the full feature roster, verified from the game's own interface and art rather than secondhand listings. Full RTP, volatility and bet-range numbers live on the full review.
The X-Unlock feature is the mechanic holding the whole game together. Rows on the grid start locked, and landing the right symbols during play opens them one at a time, so the number of active positions grows as a session goes on instead of staying fixed at 4x5 from spin one.
Every unlocked row feeds straight into the Running Wins Bonus, where coin and money symbols carry their own cash value shown directly on the reel - one confirmed example in the official game art displays a coin worth 5.00. Collect enough of those and you're working toward the Running Wins Jackpots, the six-tier ladder that caps at the Royal Jackpot. We break down the full trigger sequence in the feature-activation guide.
In practical terms, that means the first minute of a session and the tenth minute don't look the same. Early spins run on whatever rows are already open, which can feel modest. Once the X-Unlock feature starts opening more of the grid, the same 20 paylines have more real estate to pay across, and the jackpot panel starts filling in visibly rather than sitting untouched.
It's a different pitch than the usual buffalo-slot promise of "big wins from spin one." This one asks you to stick around while the grid opens up, and the jackpot ladder is the payoff for doing that.
It stacks six named features on top of the base game, and they're not cosmetic reskins of each other. Each one does a distinct job, from unlocking the grid to paying out the jackpot ladder. Here's what each covers before you spin a single reel.

None of these run in a vacuum. The X-Unlock feature opens the door, Running Wins Bonus fills the jackpot panel, and Free Spins or Lucky Riches give you extra room to build on both without dipping into your regular balance. Bonus Buy just lets you start that chain immediately instead of waiting for it to trigger on its own.
Buffalo Prime's paytable splits the usual way: card-rank symbols fill the low end, wildlife climbs through the middle, and the buffalo itself sits at the top of the regular symbols. Layered over that base set are six jackpot coin symbols, one per tier on the Running Wins ladder.
Expect the prairie cast Fugaso built the art around: eagle, wolf, elk and buffalo alongside 10-through-Ace card symbols, all rendered against a sunset backdrop. The jackpot coins are the symbols to watch. Each one carries a cash value straight on the reel, and stacking enough of them is how you climb from Mini toward Royal.
The art direction matters more than usual here because the coin values aren't hidden in a paytable menu. They're printed right on the symbol, so you can see exactly what you've collected without pausing to check anywhere else. It's a small design choice, but it's the kind of detail that makes the Running Wins mechanic easy to follow mid-spin.
The full per-symbol paytable, tier by tier, lives on the review's symbols breakdown.
Buffalo Prime X-Unlock's official RTP sits at 96.20%, with High volatility - expect smaller wins landing fairly often, with the bigger collector and jackpot payouts staying rarer. Bet sizing runs from $0.10 to $20 per spin, and the maximum win caps at 15,000x the bet, separate from the Royal Jackpot's own x10,000 ceiling.
That's the summary. Our full review goes further: what the number means for this specific game, how it should shape your bet size, and how the Royal Jackpot multiplier relates to the game's overall max win.
Size your bets against that volatility rating rather than the table minimum, and treat the Royal Jackpot's x10,000 ceiling as the standout number worth planning a session around.
It runs on Fugaso's standard HTML5 build, which means no download and no plugin on desktop, tablet or phone. The interface reflows for portrait play - Fugaso's asset set includes dedicated portrait layouts for the main UI and the bonus screens, not just a squeezed desktop view.
Expect the same 4x5 grid and jackpot panel on mobile as on desktop, with touch-friendly bet controls and autoplay. The full control-by-control walkthrough, including the mobile-specific layout, is in our how-to-play guide.
That portrait-specific art (separate files for the main UI, the bonus screens, and the Bonus Buy panel) is a stronger signal than most titles give you. A lot of slots just scale their desktop interface down and call it mobile-ready; Fugaso built Buffalo Prime's mobile layout as its own thing.
