Maxxi Labs launches Rats vs Ravens Coin Grid exclusively on Stake

Rats vs Ravens Coin Grid debuts as an exclusive title on Stake, released by Slotty Studio under the Maxxi Labs collective on 14 October 2026. The bespoke high-volatility slot carries a win potential of up to 13,283x and will remain exclusive to Stake for the lifetime of the game. The title is the latest from Maxxi Labs’ six-studio collective and follows an earlier early-release exclusive, Mad Ducks.

What Rats vs Ravens Coin Grid is and who made it

Maxxi Labs commissioned Slotty Studio to create a bespoke title, Rats vs Ravens Coin Grid, for the global online casino and sportsbook Stake. Maxxi Labs operates as a collective of six studios; Slotty Studio produced this instalment with a distinct urban theme that the developer says contrasts with Mad Ducks, the collective’s previous early exclusive for Stake. The operator relationship is a lifetime exclusive for this title, which means Stake will host the game for as long as it remains on the market.

Coin Grid mechanics and session persistence

Rats vs Ravens uses the Coin Grid mechanic to rework classic reel play into a persistent board experience. Every Cash Coin and Jackpot Coin that lands on the reels is mirrored onto a persistent grid, where it remains and accumulates from spin to spin. Players complete horizontal, vertical or diagonal lines on that grid to collect accumulated coins. Because the grid does not reset with each spin, session progression and board building become a continuous objective that players can follow across multiple spins.

The persistence of the grid creates a different player engagement profile compared with conventional reel resets. Coin Grid encourages session continuity by making the board itself the target, rather than relying entirely on single-spin outcomes.

Features that drive volatility and reward potential

The game combines Coin Grid with Hold&Win and other features to increase volatility and payout potential. Hold&Win begins with three respins, and additional rows can be unlocked to expand the playing area during the feature. Collector and Doubler symbols appear in the feature to increase rewards, and Power Mode can trigger during the base game to award coins and reduce the threshold required to reach Hold&Win.

Super Stack increases pressure on the reels by piling up symbols vertically, making it easier for high-value symbols or coins to align. Landing three or more Scatter symbols awards 10 Free Spins; during Free Spins, Super Stacked Wild or Coin symbols can dominate the reels and further boost the chance of large returns. The combined package supports the game's stated top win of 13,283x player stake.

Design and operator strategy behind the exclusive

Maxxi Labs framed the product as an example of studio-level creative freedom. A Maxxi Labs spokesperson said:

"Rats vs Ravens Coin Grid shows what can happen when Maxxi Labs studios are free to follow their own creative instincts. Slotty has combined an urban setting with Coin Grid gameplay to give the title a character all its own."

The spokesperson added that the lifetime exclusive with Stake made the release especially significant for the collective: "Mad Ducks was the first Maxxi Labs title to land an early release exclusive with Stake, bringing the farmyard chaos. Rats vs Ravens heads somewhere grittier, into neon-lit streets and an after-dark world. That contrast, and the ability to create bespoke content for an operator and its audience, is the breadth we want Maxxi Labs to be known for." The statement positions bespoke, operator-specific content as a strategic capability for Maxxi Labs’ six-studio model.

What this means for operators and players

For operators, a lifetime exclusive implies a long-term content relationship and brand differentiation for Stake’s player base. For players, the combination of Coin Grid persistence, Hold&Win mechanics, Collector and Doubler symbols, Power Mode, Super Stack and a 10 Free Spins feature with potential Super Stacked Wild or Coin dominance defines a high-volatility play profile aimed at session engagement and larger, less frequent wins.

For readers tracking releases across platforms, Rats vs Ravens Coin Grid is a clear example of operator-tailored content that links a studio collective’s creative identity to an individual operator’s catalogue. Stake’s exclusive is part of a pattern: Mad Ducks preceded Rats vs Ravens as an early Maxxi Labs exclusive, and this new title shifts tone from rural chaos to an urban night-time aesthetic.
