Cash Grotto™ Slot RTP, Details & Wager Limits
Unless you’ve played other unique Wazdan titles like Magic Spins™, you’ve likely never experienced anything quite like the Cash Grotto™ Hold the Jackpot™ slot game. It breaks from the tradition seen in many classic online slots by using 24 independent reels on a 4×6 grid.
Click the + and – buttons to set your wager, starting from just 10p up to £1,000 in the Cash Grotto™ Hold the Jackpot™ demo. That said, the top UK online casinos cap bets at £5 and disable autoplay. Outside the country, you can run 10 to 1,000 auto spins and speed up play with fast or ultra-fast modes.
The Cash Grotto™ Hold the Jackpot™ RTP of 96.13% is right on the average mark, though still a fair way off the best payout slots. Volatility is player-selectable through the chillis icon. This means you’ve got the rare flexibility of switching between low, standard, or high modes, an option that remains uncommon, even in new slots.
Considering the Cash Grotto™ Hold the Jackpot™ max win only goes up to 1,500x, I wouldn’t exactly rank it among the best online slots for potential. That said, I did manage to hit two 200x+ wins in my very first session, so the promise is there.
➡️ If this slot doesn’t quite match what you’re looking for, there are plenty of other free slots to check out.
Cash Grotto™ Theme—Prospector Adventure in Gold-Filled Caverns
My first glimpse of the game upon loading it up at Cash Grotto™ Hold the Jackpot™ casinos was a cavern scene with dim rocky walls and piles of gold scattered at the bottom. As for the reels, they looked like stone blocks edged in glowing gold. These helped create the sense of being inside a hidden treasure chamber. It’s all visually sharp, too, and polished from every angle.
The soundscape carried the echo of the cave. You’ll hear dripping water and what feels like coins falling deep in the grotto. It’s a great touch to reinforce the treasure setting. In the meantime, the effects that went off during spins and wins felt very retro. They’re the kind you’d expect from old-school titles rather than modern cinematic ones like the Cash Grotto™ Hold the Jackpot™ slot.
There are no regular symbols in the base game. Bonus symbols pay only in the bonus game or through the Moving Cash Out™ feature.
Cash Grotto™ Mobile Slot
I tried Cash Grotto™ Hold the Jackpot™ on my phone at mobile casinos, and it held up just as well as on desktop every time. The grid fit the screen nicely, and I could flip between portrait and landscape without losing any clarity.
The rather minimal and simple backdrop kept my attention on the reels, regardless of the view. Plus, nothing felt cropped or squeezed, so it played comfortably in both modes.
Cash Grotto™ Bonus Features
Cash Grotto™ Hold the Jackpot™ comes with a combination of bonus mechanics that shape how the game plays out. More particularly, you’ll see features like Moving Cash Out™, Sticky to Infinity™, Cash Infinity™, and the Hold the Jackpot™ bonus.
Moving Cash Out™
A Moving Cash Out™ symbol can land on any reel except the highlighted central ones, sticking there with a 5–15 spin countdown. Once this reaches zero, it transforms into an active Moving Cash Out™ label for another 5 to 15 spins.
If Cash, Cash Infinity™, Mini, Minor, or Major Jackpot symbols land on the same reel as an active Moving Cash Out™ label, their values are added together and stored. After every spin, the active label moves one step down, skipping over Sticky to Infinity™ symbols. Then, when it reaches the bottom, it shifts back up to the top reel.
When the active label’s countdown ends, the game draws a random percentage of 10%–100%, 150%, 200%, or 300%. This is applied to the total value the label accumulated from Bonus symbols.
Note: If you switch the bet or volatility level, Moving Cash Out™ symbols are temporarily removed. They only appear again on the same settings where they were triggered.
Sticky to Infinity™
Sticky to Infinity™ applies to Mystery and Jackpot Mystery symbols. These can appear at random in the base game. Then, they stick to the reel they land on until the end of the Hold the Jackpot™ Bonus Game.
➡️ If one lands on the highlighted central reels, it increases the chances of activating Hold the Jackpot™.
While they are present, Sticky to Infinity™ symbols stay locked in place and do not move. In the meantime, all other positions keep spinning. Once again, here, if you change the bet or volatility level, these symbols are temporarily removed. They will only return when you switch back to the settings where they first appeared.
Cash Infinity™
Cash Infinity™ symbols can randomly appear in the base game and will stick to the reels until the end of the Hold the Jackpot™ bonus game. Once they land, they remain locked in place while all other positions continue to spin.
When a Sticky symbol appears, the outcome of the remaining reels is random. And if a Cash Infinity™ symbol lands on the highlighted central reels, it also boosts the chances of activating the Hold the Jackpot™ feature.
Each Cash Infinity™ symbol carries a prize ranging from 5x to 15x your bet. These prizes are not paid immediately. Instead, you get them at the end of the bonus game.
Note: Should you adjust the bet or volatility level, the symbols are temporarily removed and will only reappear when you return to the exact settings where they were triggered.
Hold the Jackpot™ Bonus Game
You’ll need 4 bonus symbols of any type to land on the highlighted central reels to trigger the Hold the Jackpot™ Bonus Game. Here’s how it works:
- Cash symbols can award values from 1x to 10x your bet
- Mini, Minor, and Major Jackpot symbols trigger prizes of 10x, 20x, and 50x your bet, respectively
Note: Multiple Jackpots of the same type can be won in one round.
- Collector symbols collect all values from Cash and Cash Infinity™ symbols and multiply the total by 1x to 20x
- Mystery symbols can transform into any bonus symbol except Cash Infinity™, and Jackpot Mystery symbols change only into Mini, Minor, or Major Jackpots
Hold the Jackpot™ starts with 3 respins, and every bonus symbol that lands sticks to the reels until the feature ends. Each new one that appears resets the counter back to 3. It keeps going until no respins are left, or until all 24 reel positions are filled with bonus symbols.
When the Bonus Game ends, all winnings are calculated. The prize is the sum of all Bonus symbol values, including any Jackpots, unless the Grand Jackpot is triggered. Speaking of, to win the Grand Jackpot of 1,500x your bet, you need to fill all 24 positions with Bonus symbols.
Gamble Feature
The Gamble feature gives you the option to risk your win for a chance to double it by picking one of two symbols. You can repeat this up to seven times, but choosing wrong means you lose the entire amount.
Chance Level™ & Bonus Buy (Not Available in UK Online Casinos)
You can activate Chance Level™ in the base game at x2, x5, or x10. This multiplies your bet by 2, 5, or 10. It also boosts your chance to trigger Hold the Jackpot™ by at least 2x, 6x, or 12x, respectively.
Payout values do not change—symbol amounts stay the same as on the base bet in both the base and bonus games. Additionally, changing the Chance Level™ temporarily clears any sticky symbols. They only show again on the same Chance Level™ where they first appeared.
As for the bonus buy, you can pick from the following options depending on the volatility setting:
- Low (50x): Cash symbols + 1 Cash Infinity™
- Standard (75x): Cash symbols + 1 Cash Infinity™ + 1 Mystery
- High (100x): Cash symbols + 3 Cash Infinity™ + 1 Mystery
- Extreme (250x): Cash symbols + 4 Cash Infinity™ + 1 Mystery + 1 Jackpot Mystery
- Double Extreme (500x): Cash symbols + 5 Cash Infinity™ + 2 Mystery + 1 Jackpot Mystery
Cash Grotto™ Verdict: A Bonus-Driven Cave Slot With Adjustable Volatility
It didn’t take Cash Grotto™ Hold the Jackpot™ long to catch my attention with its unique 24-reel setup. The cavern theme gave the game a strong sense of place. Plus, the volatility controls made it very easy for me to shape the experience to how I wanted to play. That said, the 1,500x max win is not the strongest element.
I found the biggest draw to be how features such as Moving Cash Out™, Sticky to Infinity™, and Cash Infinity™ worked together. I love how they each add a different way to build value. Also, the Hold the Jackpot™ bonus game pulled everything into one place, even if hitting the Grand is a tough ask.
