Cash Grotto features

Moving Cash Out
There are no regular symbols in the base game and Bonus symbols pay only in the Bonus Game. However, a Moving Cash Out™ symbol can appear on a random reel except highlighted central reels and will stick to it from 5 to 15 spins before it becomes active. When the countdown reaches 0, the symbol transforms into an active Moving Cash Out™ label for 5 to 15 spins. If Cash, Cash Infinity™, MINI, MINOR or MAJOR Jackpot symbols are drawn on the reel with the active Moving Cash Out™ label, their value is accumulated. With each spin, the active Moving Cash Out™ label moves down avoiding the Sticky to Infinity™ symbols. Once it reaches the bottom edge it moves to the top reel. When the Moving Cash Out™ label countdown reaches 0, a percentage ranging from 10% to 100%, 150%, 200% or 300% is randomly drawn. The percentage of the sum of Bonus symbols' values is then paid out.
Sticky to Infinity
Mystery and Jackpot Mystery symbols with the Sticky 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 Sticky to Infinity™ symbols are locked in place while other symbols are spun. If the Sticky to Infinity™ symbol is drawn on the highlighted central reels, it increases the chances of activating the Hold the Jackpot™ Bonus Game.
Bonus Symbols

Hold the Jackpot Bonus Game — reels and re-spins
The game is played on 24 reels. All Bonus symbols stick to the reels during the Bonus Game. 3 Re-Spins are granted at the beginning of the Bonus Game.

Chance Level
The game is played with the base bet set by default. However, the Chance Level™ feature 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 at least a 2x higher chance of activating the Hold the Jackpot™ Bonus Game. Chance Level™ x5 - the base bet is multiplied by 5, giving you at least a 6x higher chance of activating the Hold the Jackpot™ Bonus Game. Chance Level™ x10 - the base bet is multiplied by 10, giving you at least a 12x higher chance of activating the Hold the Jackpot™ Bonus Game. 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.

Cash Grotto: Explore Wazdan's High-Volatility Treasure Cave


Game Overview & Theme


Cash Grotto immerses you in a beautifully rendered underwater cavern. The visuals are a blend of dark, rocky textures and the shimmering glow of submerged gold, creating an atmosphere of secret wealth. Symbols on the reels include classic card suits (10-A) styled as carved stone, alongside thematic icons like golden frogs, ornate chests, and majestic idol masks. The soundtrack complements the theme with mysterious, ambient echoes and satisfying clinks and crunches during wins, enhancing the feeling of uncovering hidden loot. It's a distinct aesthetic that stands out in the crowded field of underwater & ocean slots.

How to Play Cash Grotto: Rules & Betting


Cash Grotto uses a 5x3 grid setup but moves away from traditional paylines, employing a "Ways to Win" system where matching symbols on adjacent reels from the leftmost side award a win. This can lead to frequent, smaller combinations. The betting range is exceptionally wide, catering to all player types. You can start your treasure hunt with a minimum bet of just €0.10 and, for the high-rollers, scale up to a massive €10,000 per spin—one of the most generous max bets in the industry. Always remember to set your bet comfortably within your limits using the intuitive interface before spinning the reels.

Symbols, Payouts & Special Features


The lower-value symbols are the stylized 10, J, Q, K, and A. The premium symbols are the thematic golden artifacts: the Frog, the Chest, and the Idol. The Idol is the most valuable standard symbol. The game features two key special symbols that unlock its potential:



  • Wild Symbol: Depicted as a glowing "WILD" gemstone, it substitutes for all regular symbols to help form winning combinations.

  • Scatter Symbol: Represented by a golden door or entrance, this symbol is key to triggering the main bonus feature.

The Cash Grotto Bonus Feature


This is the heart of the game and where its name truly comes to life. Landing 3, 4, or 5 Scatter symbols anywhere on the reels triggers the Cash Grotto Free Spins feature. You are first taken to a second screen—the interior of the treasure grotto—where you are awarded a set number of free spins. The number of spins depends on the number of Scatters that triggered the feature (e.g., 3 Scatters might award 8 spins).


Inside the Cash Grotto, the reels are filled with special cash symbols, each bearing a random cash value or one of three jackpot prizes (Mini, Minor, Major). During the free spins, a multiplier is also active and increases with each spin. The goal is to land cash symbols, which are collected and added to your total win. If you're lucky enough to fill the entire grid with cash symbols, you'll unlock the Grand Jackpot. This feature is a thrilling, high-tension bonus round that perfectly encapsulates the high-volatility nature of the slot.

Volatility, RTP & Max Win Potential


Cash Grotto is unequivocally a high-volatility slot. This means wins may not land on every spin, but when they do, they have the potential to be significant. The 96.13% RTP is solidly above the industry average, indicating a favorable theoretical return over an extended period. The maximum win is advertised at up to 5,000 times your stake. When combined with the max bet of €10,000, the potential payout is staggering, squarely aiming this game at players with a taste for substantial risk and reward. It's a similar adrenaline rush to what you might find in other high-potential games like 9 Coins 1000 Edition or 12 Coins Grand Gold Edition Halloween Jackpots.

Graphics, Sound & Mobile Experience


Wazdan has delivered a polished product with Cash Grotto. The graphics are crisp and detailed, with smooth animations, particularly during the bonus feature. The sound design is atmospheric without being intrusive, letting the anticipation of big wins build.
