Whales of Cash is an underwater-inspired game and follows a story of aquatic animals stumbling upon sunken treasures and guarding them. The reels of the game are set on a background of the deep blue sea. This online slot has several sea creatures as its symbols which is expected given its theme. You’ll find the starfish, pearl-holding oyster and octopus trying to get out of an empty treasure chest.
An orca holding a bag of money serves as the wild symbol while the scatter is a green bag of money. When playing, you try to win a payout by landing any of these elements 3-5 times in a spin to earn their corresponding coins.
This online slot doesn’t have the most striking look. However the graphics still look very appealing. Aristocrat has put effort into crafting symbols with meticulous detail, creating a strikingly realistic look for each animated sea creature. You will find pearl-holding oysters, mischievous octopus trying to escape from a treasure chest and so much more. The vibrant color also enhances the underwater theme beautifully. It blends deep blues with bursts of bright colors that keep players visually engaged.
Like many Aristocrat products or from other software providers, the sound is subtle. You mostly hear the satisfying clicking of the reels locking into place after each spin. This allows you to focus on the game at hand. You get a short celebratory jingle whenever you win a payout, but the real fun starts during bonus rounds. You get a more Vegas-style musical score playing throughout the session. This helps create a sense of excitement which keeps the energy high. The shift in tempo also makes the bonus rounds feel more rewarding while also building anticipation for the next time you get to hear it.
The Whales of Cash slot is played on a 5×3 reel and has 243 fixed ways to win. So instead of the traditional way of landing a payout, the massive payline means you only need to have matching symbols on adjacent reels to land a win.
While this setup is rewarding, the real deal is during the Deluxe Xtra Reel Power Free Games feature. This bonus round adds 1 reel to the initial one to make it 5×4. Additionally, the payline increases from 243 to 1,024 ways to win. The reel and payline aren’t the only upgrades you get during this round. Wild appearing on reel 2 comes 5x multiplier; reel 4 wild has a random 4x, 5x or 5x multiplier.
There are several impressive bonuses at the Whales of Cash slot that can improve your payout. Below are what the online slot has to offer and how you can trigger them.
An orca holding a bag of money is the wild symbol. The symbol only appears on reels 2 and 4 and can substitute all symbols besides the scatter. During base play, any win formed with the wild comes with a 2x multiplier each.
A bag of money represents the scatter symbol. Landing the scatter 3-5 of its kind can also give you anywhere between 5-50 coins. If the symbol appears without substituting for a deluxe scatter symbol, the free games feature is triggered. There will be 10, 15 or 25 free games. During the bonus round, the wild multipliers increase to 4x or 16 depending on the number that appears on the reels. This feature can be retriggered countless times when using the free spins, which can increase your win exponentially.
This Whales of Cash slot online feature is activated when 3, 4 or 5 scatter is landed in a spin, it changes to deluxe scatter symbols. Depending on the number of symbols that triggered this feature, you will be prompted to choose between the following:
Reel power free games round is played on the usual 5×3 grid with 243 paylines, and for each wild symbol on reels 2 and 4, you get a 4x multiplier. This means your winnings can have up to 16x multiplier. For xtra reel power free games, the reel is extended to a 5×4 grid with 1,024 ways to win. Landing a wild symbol during a win pays out up to 40x your win. Reel 2 wild symbol is multiplied by 5, while the wild symbol on reel 4 is multiplied by 4, 5 or 8 randomly.
Even if you are not able to land bonus-triggering symbols in a spin, this online slot has you covered. During the bought game, the free games or deluxe choice bonus can be randomly triggered, which allows you to boost your potential payouts.
The Whales of Cash slot can be played with as low as 30 cents per spin. Even if you are a high roller, the $3 max bet still allows you to test the game’s high-risk, high-reward possibilities. Most symbols at this slot require you to land at least 3 matching symbols on a payline. However, 10 and 9 numbers from the suit of card award 2 coins if you land 2 matching symbols on a payline.
The most rewarding symbol is the starfish. Landing 3, 4 or 5 in a spin wins you a payout of 300, 800 or 1,500 coins in the base play. Followed by this are a pearl-holding oyster, crab and octopus in chest symbols, which can be up to 1,000 when landed 5 times. Besides the 10 and 9 symbols, other suits of card symbols in this online slot include A, K, Q and J. These symbols provide between 3 and 100 coins when you land between 3 and 5 of a kind.
The RTP for the Whales of Cash slot is set at 94.15%. This means, theoretically, you get about $94.15 for over $100 wagered over extended play. Although the RTP is slightly lower than the average 96%, its mid-high volatility pretty much makes up for it, especially if you enjoy balanced risk and reward.
The mid-high variance means the online slot machine frequently awards smaller wins, occasionally followed by a burst of higher payouts. The balance that the Whales of Cash slot online offer makes it ideal for gamblers who find low-variance slots too slow and predictable and high-volatility slots too extreme and risky. When you add the lucrative symbols and generous bonus rounds together, it becomes understandable why this online slot is popular among newbies and experienced high rollers alike.
Due to this slot’s RTP and volatility, we recommend that you should be patient, as this is the best way to make the most of this game. The potential for better returns lies in holding out, winning smaller payouts in the base play till you trigger any of the bonuses to win up to 50 free spins or a boost of up to 40x.
While Whales of Cash doesn’t offer a fixed or progressive jackpot, the game’s other rewarding features make up for it with plenty of chances to secure high payouts. It relies on its valuable symbols, generous multipliers and exciting bonus features to keep the wins coming, instead of a life-changing jackpot prize
For instance, you can retrigger the free games feature indefinitely. This gives players ongoing opportunities to boost their winnings. With multipliers that can go up to 40x during bonus rounds, there’s no shortage of potential for impressive payouts, making Whales of Cash a thrilling game for both casual players and high rollers.
The Whales of Cash slot ticks many boxes for players of all kinds. In addition to being visually appealing, the slot’s 243 base paylines and 1,024 free game paylines mean players have massive opportunities to score payouts with every spin. Beyond just the paylines, the high-value symbols and rewarding bonus features create an exciting experience that caters to both low and high rollers, allowing them to enjoy steady wins and thrilling multiplier boosts.
