Cash Grotto™
Cash Grotto™ delivers a descent into a treasure-stacked cavern where the theme is pure profit. The game’s area is filled with the glint of gold, and its symbols are solely coins and sealed doors. These portals conceal the game’s core promise of instant prizes, jackpots, and golden mysteries. Within this atmospheric cave, players have the chance to uncover rewards and pursue a maximum win of 1500x their stake, making every spin a potential treasure hunt.
Cash Grotto™ Gameplay and Mechanics
Cash Grotto™ is built on a unique 6×4 grid with 24 independent reels, eliminating traditional paylines and symbols. The entire experience is driven by its innovative features. The core loop involves collecting bonus symbols via the Moving Cash Out™ token and elevating the Chance Level™ to increase win potential. This culminates in the Hold the Jackpot™ bonus, triggered by landing four bonus symbols on the central reels. Within this round, features like Cash Infinity™ and Sticky to Infinity™ can activate, locking symbols for massive payouts.
Players can tailor the pace with Volatility Levels™ and Ultra Fast Mode, or instantly access the action through the Buy Feature.
Cash Grotto™ Theme and Visuals
Cash Grotto™ fully commits to its premise of subterranean wealth. The game is set deep within a cavern where the walls glisten with embedded gold coins and precious gems. The visual design is intentionally functional; the reels are populated not by thematic symbols, but by pragmatic icons like gleaming coins and sealed vault doors. The sound design deepens this immersive atmosphere, featuring the echoes of dripping water, shifting rocks, and the deep, resonant clinks of metal striking gold. These audio cues build suspense, making every spin feel like a step deeper into a treasure-laden cave where immense riches are waiting to be unearthed.

Cash Grotto™ Slot Features
Cash Grotto™ is defined by a suite of innovative features that create a highly strategic and fast-paced experience. Let’s pace into the mines to see the riches all players stand to win.
Moving Cash Out™
In the base game, the only way to collect wins is through the Moving Cash Out™ feature. A marker appears on a random reel and becomes sticky for 5-15 spins. Once its countdown ends, it activates and begins moving down the reels for another 5-15 spins.
As it moves, it collects the values of any Cash or Jackpot symbols it encounters on its current reel. When its active countdown finally expires, a random multiplier between 10% and 300% is applied to the total accumulated value, which is then paid out to the player.
Sticking To Infinity™
Mystery and Jackpot Mystery symbols with the Sticking To Infinity™ feature may randomly appear in the base game and stick to the reels until the end of the Hold the Jackpot™ Bonus game. All Sticking To Infinity™ symbols are locked in place while other symbols are spun. If the Sticking To Infinity™ symbol is drawn on the highlighted central reels, it increases the chances of activating the Hold the Jackpot™ Bonus Game.
Bonus Symbols
Drawing 4 Bonus symbols of any type on the highlighted central reels activates the Hold the Jackpot™ Bonus Game.
Cash Infinity™
Cash Infinity™ symbols may randomly appear in the base and stick to the reels until the end of the Hold the Jackpot™ Bonus Game. All Sticky Cash Infinity™ symbols are locked in place while other symbols are spun. Cash Infinity™ symbols award prizes ranging from 5x to 15x the player’s bet. However, the prize will be paid at the end of the Bonus Game. If the Cash Infinity™ symbol is drawn on the highlighted central reels, it increases the chances of activating the Hold the Jackpot™ Bonus Game.
Hold the Jackpot™ Bonus Game
This bonus round is played on all 24 reels. Players begin with 3 re-spins, and each new Bonus symbol that lands resets the count back to 3. The game continues until no re-spins remain or all reels are filled.
Cash symbols award prizes from 1x to 10x the bet, while Mini, Minor, and Major Jackpots can land randomly. The Collector symbol gathers all visible Cash values and applies a random 1x-20x multiplier. Mystery symbols transform at the round’s end.
The top prize is the Grand Jackpot, awarding 1500x the bet for filling all 24 reels with any single symbol type. This maximum win is paid independently of other collected values.
Chance Level
The game can be enabled during the base game, and you can select one of 3 levels.
Chance Level x2 – the base bet is multiplied by 2, giving you a 2x higher chance of activating the Hold the Jackpot Bonus Game.
Chance Level x5 – the base bet is multiplied by 5, giving you a 6x higher chance of activating the Hold the Jackpot™.
Chance Level x10 – the base bet is multiplied by 10, giving you a 12x higher chance of activating the Hold the Jackpot™. The Chance Level feature does not affect the paytable; thus, symbol values remain the same as for the base bet in both the base game and the Bonus game. Sticky symbols are temporarily removed from the reels when changing Chance Level and only appear on the Chance Level they were obtained on.
Gamble Feature
The Gamble feature allows you to potentially double your win. After any win, you can choose to gamble for up to 7 rounds. In each round, you pick one of two symbols for a chance to double your prize. You can collect your winnings after any successful guess. However, an incorrect guess at any point loses the entire amount from the original trigger win. The maximum potential win from this feature is capped at FUN 7,500,000.
