Crystal Waters is an aquatic/underwater RealTime Gaming (RTG) slot that impresses with its return-to-player (RTP) percentage. The online slot starts with a splash screen showing a cute dolphin that plays a more significant role later in the reels. But the top highlight is the 97.5% RTP, making it one of the highest RTP slots ever. There aren’t many slot games that touch that number. Specs-wise, it’s a highly volatile slot with several features, 20 paylines, and a standard 5×3 setup. Read our Crystal Waters slot review below to see why it’s an excellent pick for all players.

Themes in Crystal Waters

As the name suggests, Crystal Waters’ action is set deep under the sea. RTG has designed a visually pleasing title, albeit a bit dated. Still, the dolphin―one of the world’s most intelligent mammals―symbol and all others look decent and, dare we say it, photorealistic. From wild dolphins to crabs and scattered yachts, it’s a crystal-clear game you should try. It certainly looks much better than the studio’s top penny slot machines.

Crystal Waters Slot

Crystal Waters Symbols

The list of symbols in the Crystal Waters slot features marine life under sea level. Dolphins, crabs, seashells, seahorses, and a yacht grace the reels. They all look realistic, so this isn’t a cartoonish slot under the sea.

Regular Symbols

A sea turtle, tang fish, horse, and shell lead the regular symbols. All these beautiful sea creatures are high-paying symbols, while the card royals pay less.

Wild Symbols

A dolphin symbol is a wild symbol in Crystal Waters by RTG. It substitutes for other symbols in a winning combination. The prize is doubled when one or more dolphins are part of a winning combo.

Bonus Symbols

Scattered yachts are the bonus symbol in the Crystal Waters online slot machine. They are added to line wins and multiplied by total bets. As expected, the scatter is key for the game’s special features.

Paytable and Winning Combinations

Like most RTG slots, Crystal Waters uses a basic math model. It has 20 paylines with regular wild and scatter features that substitute for a missing symbol and trigger the bonus round. A quick playthrough for fun will give you all the details, but it’s clear that this isn’t a complete Megaways or Cluster Pays slot. The only surprise is that the high-paying symbols in the slot machine pay for combos of two or more instead of three plus, like in other RTG slot games.

Crystal Waters Slot Paytable
  • Sea turtle: 2,000x for five, 500x for four, 100x for three, and 5x for two.
  • Tang fish: 1,250x for five, 200x for four, 50x for three, and 3x for two.
  • Sea horse: 1,000x for five, 75x for four, 20x for three, and 2x for two.
  • Seashell: 1,000x for five, 75x for four, 20x for three, and 2x for two.

Free Spins and Bonus Rounds in Crystal Waters

There are two special features in the Crystal Waters game. Like in most slot games, one is a regular free spin round, while the other is a random progressive jackpot.

Crystal Waters Bonus

Free Spins Bonus Round

Three or more yachts across the five reels reward 15 free spins. During this round, a bonus fish may appear on the third reel and substitute for other symbols except for the scatter symbol. The cool thing about this tropical fish is that every time it substitutes a symbol in a win, it multiplies it by x2, x4, or x8. When appearing in combination with a dolphin, the values are cumulative. In this feature, you can win up to x16 pays.

Landing a yacht symbol trio will retrigger the bonus, with no limit to the number of retriggers.

Progressive Jackpot

The random jackpot can be won anytime, and you don’t need to play at max bet to receive it. Its contribution is no more than 1.5% of any bet. Start playing the Crystal Waters slot, and if you’re lucky, you’ll be the next great jackpot winner on a random spin.

Crystal Waters no DownloadHow to Play for Free

The Crystal Waters slot machine is available for free here on this page. We don’t need you to register or download an appyou can play it on your mobile devices straight from a browser. It’s guaranteed fun when you do, but spinning the demo version is crucial before you start playing for real money. We have other free games on offer, too, all without signing up or downloading.

You can also play the slot game in Café Casino, but you must register with the casino first. Online casinos typically won’t allow you to play free games as a guest. Also, the casino has a great collection of real-money video slots you might try.

Can You Use a Casino Bonus to Play Crystal Waters Slots?

Yes, you can. The best online casinos will have a variety of bonuses that you can put to good use in this game and others. You’ll hit wins left and right when the bonus fish substitutes for others and boosts wins with multipliers, but without breaking your bankroll.

However, before you claim a bonus, ensure you’ve read the terms. They need to be fair to make the most out of the bonus. When playing through your bonus funds, check out the slot guides, too, so you’re sure you know what you’re doing.

Jackpots in Crystal Waters

There’s one random jackpot on offer in the Crystal Waters online slot. It is won on a lucky spin, with no prerequisites to claim it. We’ve seen such RTG progressive jackpots in other slots, such as Darkness Divas. We suggest trying the demo mode to see how it works and if it lands often.

What is the Highest Payout in Crystal Waters?

Like in most RTG slots, the highest payout in Crystal Waters is locked at 50,000x the bet. That’s the progressive jackpot, so you can’t win it by any combination of special symbols.
