In mid-September, Maxxi Labs, a group of six independent studios, chose Stake as its first stage. Its first game, “Mad Ducks”, came out as an early exclusive, released on Stake first. A month later, Maxxi Labs went a step further. “Rats vs Ravens Coin Grid,” released on October 14, is offered only on Stake, and will stay that way for the life of the game.
Lifetime exclusivity is not the same as early exclusivity
An early exclusive means releasing to one operator a few weeks ahead and supplying other operators later. A lifetime exclusive is a game made only for that operator, so you will not see it at other casinos. Maxxi Labs said it wants to use this game to show it can create tailored content for an operator and its player base.
It was made by Slotty, one of the studios under Maxxi Labs. It puts two mismatched rivals, rats and ravens, on a neon-lit night street. Maxxi Labs described it as a rougher city atmosphere, in contrast to the farm antics of Mad Ducks.
Coins stay on the board and stack up
The core mechanic is the coin grid. A separate grid sits on top of the reels as an extra layer. When a cash coin or jackpot coin lands on a reel, the same spot is marked on the grid too. These coins don’t disappear when the spin ends. They stay and stack up.
When you fill a row on the grid, whether horizontal, vertical, or diagonal, you collect the coins in that row. Unlike a typical slot where the grid resets every spin, the result of the previous spin carries over to the next. It feels closer to filling in a bingo card. Maxxi Labs said this approach gives players a clear goal and makes sessions longer.
Maxxi Labs’ “Skulls and Souls Bonanza Coin Grid” uses this Coin Grid as well. The Coin Grid appears to be settling in as a series mechanic within Maxxi Labs.
Hold and Win starts with 3 respins and expands the board
Hold & Win starts with 3 respins. As you progress, locked rows unlock and the grid expands. During the bonus, Collector symbols and Doubler symbols grow the prizes. As the name suggests, Collectors gather coin values, and Doublers double them.
The base game has a Power Mode. When Power Mode is on, it awards coins and lowers the requirements for entering Hold & Win. It speeds up both the path to filling the grid and the path to the bonus at the same time.
Super Stacks and free spins
Super Stacks pile the same symbol high across entire reels. With 3 or more scatters, 10 free spins begin, and during them, wilds or coin symbols stacked as Super Stacks can take over entire reels. As coins pile up, the grid fills that much faster.
In short
“Rats vs Ravens Coin Grid” is a slot made by Maxxi Labs’ studio Slotty and released on October 14, 2026 as a Stake lifetime exclusive. It features a Coin Grid where you complete lines to collect coins, a Hold & Win that starts with 3 respins and expands the grid, a base game Power Mode, Super Stacks, and 10 free spins. Volatility is very high and the max win is 13,283x. RTP and bet range were not given in the announcement.
