Primal Buffalo PowerGrid: Booming Games adds PowerGrid mechanic to Buffalo series

Booming Games has released Primal Buffalo PowerGrid, a new entry in its Buffalo slot series that adds a coin-based PowerGrid mechanic and jackpot outcomes to the franchise. The game went live on 15 October 2026 and runs on a 4x5x5x5x5x4 layout offering 10,000 ways to win; it also includes a Buy Bonus option priced at 20x the selected bet.

What the Primal Buffalo PowerGrid layout and win rules mean for play

Primal Buffalo PowerGrid uses a non-standard reel configuration: two outer reels with four positions and four central reels with five positions, creating a 4x5x5x5x5x4 grid. Standard wins pay when three matching symbols appear on adjacent reels, regardless of their vertical position, which maintains the series' typical adjacency-pay model while expanding the number of symbol combinations to 10,000.

The game continues the Buffalo theme but layers in additional mechanics that sit alongside those base-game payouts. Operators evaluating the title will note that the adjacency rule keeps the base-game math familiar to players of previous Buffalo releases, while the new PowerGrid system supplies incremental win opportunities outside the core symbol-matching engine.

How the PowerGrid mechanic works and where it appears

The PowerGrid feature is split into two separate grids that occupy reels 2–3 and reels 4–5. Each grid reacts to coin symbols landing in its area:

• A coin symbol that lands in a grid activates that grid and locks the coin in place for three spins.

• If additional coin symbols appear while a grid is active, the three-spin counter for locked coins resets.

• When a grid fills completely, the total value of all locked coins in that grid is paid to the player in addition to any simultaneous base-game win.

The locking mechanism therefore creates short-term accumulation windows: coins can build over up to three spins, and operators can expect bursts of coin payouts when a grid completes. The two-grid design means these windows can occur independently on the left and right central reel blocks.

Prize Reels, Ultra Prize Reel and the jackpot structure

Prize Reel symbols can land inside an active grid and trigger an Ultra Prize Reel spin. That Ultra Prize Reel can award:

• multipliers that are applied to the value of locked coins,

• one of four jackpot pots labelled MINI, MINOR, MAJOR or GRAND,

• or a COLLECT icon that immediately awards a win and ends the feature.

When a multiplier is awarded by the Ultra Prize Reel, that multiplier increases the payout associated with coins already locked in the grid. If a jackpot pot is landed, the corresponding MINI, MINOR, MAJOR or GRAND prize is paid according to the game's internal jackpot configuration.

Free Spins, coin value treatment and the Buy Bonus option

Free Spins in Primal Buffalo PowerGrid trigger when three or more buffalo scatter symbols appear. The number of awarded spins scales with the number of scatters:

• three scatters award 6 free spins,

• four scatters award 8 free spins,

• five scatters award 10 free spins,

• six scatters award 12 free spins.

During Free Spins, coin values that land are accumulated and paid at the end of the feature rather than immediately; completed PowerGrids during Free Spins also pay out and then reset. Players who prefer to bypass qualification can use the game's Buy Bonus option, which prices direct entry to Free Spins at 20x the selected bet.

Product positioning and operator considerations

Blooming Games positions this release as an evolution of the Buffalo format, combining the familiar adjacency pays and high hit-profile theme with added jackpot and coin-accumulation mechanics. For operators, the title presents a few clear commercial and technical notes:

• The 10,000-ways layout and adjacency rule should make gameplay intuitive to existing Buffalo players while offering a higher frequency of small wins.

• Coin locks and short three-spin accumulation windows produce intermittent larger payouts, which may affect volatility profiles compared with earlier Buffalo titles.

• The inclusion of four progressive-style pots (MINI, MINOR, MAJOR, GRAND) and an Ultra Prize Reel introduces content that can be marketed around jackpot moments.

Operators preparing for deployment should review integration points for progressive pools and ensure their reporting captures grid-trigger events and Ultra Prize Reel outcomes for compliance and player-protection analytics. Platform suppliers will need to support the game's reel configuration and the Buy Bonus purchase flow as part of the standard wallet and transaction stack.

Developer comment

“An action-packed new entry in our popular Buffalo series of slots, Primal Buffalo PowerGrid offers an entirely new twist on the format thanks to its unique PowerGrid system,” said Craig Asling, Director of Games at Booming Games. "With this innovative mechanic capable of adding coin wins and jackpot prizes to every spin in both the base game and the bonus, it’s one of our most ambitious features to date and will surely prove to be a huge hit with players and operators alike."

The statement frames the release as a deliberate extension of the brand's mechanics and highlights the intention to combine base-game action with jackpot-style reward structures.

Where readers can compare this release and next steps for operators

Editors and product teams reviewing new slot line-ups will find Primal Buffalo PowerGrid relevant to both casino content and commercial scheduling. The game is appropriate for casino listings and should be flagged in platform feeds so operator marketing teams can plan promotional windows around the Buy Bonus and jackpot features. Commercial teams may also want to coordinate product briefs with their b2b suppliers to confirm telemetry and reporting of PowerGrid events.

Technical and compliance teams should log Ultra Prize Reel triggers and jackpot awards in transaction records and ensure the Buy Bonus flow is aligned with wallet and responsible‑gaming controls.

Blooming Games' new PowerGrid entry broadens the Buffalo series' feature set while preserving the adjacency-win structure players expect. The mix of coin locks, multipliers, prize pots and a 20x Buy Bonus gives operators several levers to shape player journeys and promotional messaging.
