Maxxi Labs launches Rats vs Ravens Coin Grid exclusively for Stake players

Maxxi Labs has introduced Rats vs Ravens Coin Grid, an online slot developed by Slotty Studio specifically for Stake. According to the announcement, the game is exclusive to the operator for the lifetime of the title. It pairs two unlikely rivals in a neon-lit urban setting with a persistent coin-collection system at the centre of play.

The release is presented as part of Maxxi Labs’ collective of independent studios. It combines a very high-volatility profile with a stated maximum win potential of up to 13,283 times the stake. That figure is a top-end product claim, not a prediction of an individual session or an indication of how likely the maximum outcome is to occur.

An urban rivalry built around a persistent grid

Rats vs Ravens Coin Grid places its conflict in a gritty city environment, contrasting rats on the streets with ravens above them. The theme gives the game a distinct identity while keeping the mechanics focused on collecting coins and completing a board. Instead of treating every spin as a separate event, Coin Grid carries certain collected symbols forward.

The Coin Grid mechanic layers a grid over the traditional reels. When a Cash Coin or Jackpot Coin appears, it is also represented on the grid and stays there as play continues. The objective is to complete a horizontal, vertical or diagonal line to collect the accumulated coins. This creates a second route to potential rewards alongside the standard reel-based result.

The persistent layout lets players see which positions are filled and which parts of the grid remain incomplete. That continuity may make spins feel connected, although it does not guarantee that a line will be completed or a reward collected.

Hold&Win adds another layer of progression

The Hold&Win feature is a central part of the game. The announcement says it begins with three respins, while unlocked rows can expand the playable area as the feature develops. Collector and Doubler symbols can then influence the rewards gathered during the feature.

Power Mode can also activate during the base game. According to the description, it can award coins and lower the threshold required to progress towards Hold&Win. This links the regular spins with the bonus feature rather than limiting all progression to a separate round. Results still depend on the symbols that appear and the game's programmed rules.

Super Stack and free spins broaden the feature mix

Super Stack piles symbols across the reels. The game also includes a free-spins feature, triggered when three or more Scatters appear. That sequence awards 10 free spins, during which Super Stacked Wild or Coin symbols can occupy the reels.

These mechanics give the title several interacting features. Coin Grid centres on persistent collection, Hold&Win uses respins and an expanding board, while Super Stack and free spins introduce other symbol combinations. The design is built around changing board states and feature interactions, but outcomes remain dependent on each game result.

A bespoke release for Stake

The exclusivity arrangement is a notable part of the announcement. Rather than presenting Rats vs Ravens Coin Grid as a general release across multiple operators, Maxxi Labs positions it as a title tailored for Stake and its audience. Bespoke development can give a studio room to shape a game's setting and feature mix around a specific distribution partnership.

The announcement also places the game alongside Mad Ducks, an earlier Maxxi Labs title described as receiving an early-release exclusive with Stake. The two titles use different visual worlds: Mad Ducks takes a chaotic farmyard approach, while Rats vs Ravens moves into neon-lit streets and an after-dark city atmosphere. The contrast reflects the collective's stated aim of supporting distinct concepts across its studio brands.

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.

“And the lifetime exclusive with Stake makes this one particularly exciting. 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.”

What the volatility claim means for players

The stated maximum win potential of 13,283x is a possible upper outcome under the game's rules, not an expected return or a promise. The description labels the game very high volatility, a term generally used for games where results can vary substantially over time. A large top-end figure does not establish the probability of reaching it.

The announcement does not state a return-to-player percentage or a probability for the maximum win. Players should review the game information and terms made available by the operator in their jurisdiction before playing. Availability and consumer protections can differ by location.

Independent information may also help players understand the wider gambling environment. The Gambling Commission publishes regulatory guidance for Great Britain, eCOGRA describes testing and certification services for online gambling products and Gambling Therapy offers support to people affected by gambling-related harm. These references are general signposts and do not imply that this specific game or either company holds a particular certification or approval.

Conclusion

Rats vs Ravens Coin Grid gives Maxxi Labs a distinctive title to offer through its exclusive Stake arrangement. Its main point of difference is the persistent Coin Grid, which keeps Cash and Jackpot Coins visible across spins and makes line completion an ongoing objective. Hold&Win, Power Mode, Super Stack and free spins add further layers to that central mechanic.

Its urban theme separates it from the lighter setting of Mad Ducks, while the stated 13,283x maximum win potential and very high-volatility classification place it firmly in a high-variance category. The release also illustrates Maxxi Labs’ focus on bespoke content for an operator’s audience.

Ultimately, the game's appeal rests on the combination of its persistent collection mechanic, expanding bonus features and distinctive visual identity. Its exclusive distribution arrangement gives the release a clear commercial position, while its feature mix distinguishes it from more conventional reel-based slots. For players assessing the title, the important distinction is between advertised features and uncertain outcomes: the mechanics describe what may be possible, not what an individual should expect.
