RTG is one of the most popular developers of Bitcoin slots for the American audience and it’s easy to see why. RTG games are always packed full of bonus action and there is often a lot to be won from spinning them. A classic title from this company is Crystal Waters, a 20 pay line Bitcoin slot with a relaxing, underwater theme and plenty of special features to enjoy.
The original version of this slot was first released all the way back in 2006 and an updated mobile-friendly adaptation came out in 2014. Not much has been changed from the earlier desktop version and in many ways it’s obvious that Crystal Waters is now over a decade old. In an industry where brand new Bitcoin slots are being constantly released, each one more innovative than the last, it’s easy for older games to appear outdated and clunky. Fortunately the underwater theme is one that stands the test of time but the graphics of Crystal Waters don’t stand out in any way.
All of the settings options for Crystal Waters can be seen at the bottom of the screen. By clicking the up and down arrows beneath the game, players can adjust the number of active pay lines – from 1 to 20 – and the value of the coins on each line – from 1c to $5. This leaves a full betting range of 1c to $100 per spin.
The reels are filled with an assortment of aquatic animals such as seahorses, goldfish, dolphins, turtles and vibrantly colored tropical fish. Other symbols include boats and standard playing card values. Finding a matching combination of at least two of these marine-themed images can make for some impressively high payouts. The Sea Turtle is the highest value symbol in the game, five turtles at once will award 2,000X credits and this amount will be doubled if a dolphin appears on the reels at the same time. Crystal Waters benefits from a progressive jackpot which is awarded totally at random and can occur after any spin made with real money in the base game.
As mentioned earlier, the wild dolphin symbol doubles the winning amount whenever it shows up on a successful spin. This wild will also substitute for any other symbol on the reels – apart from the yacht scatters – boosting the chances of landing on a winning combination. Finding three or more of the yacht scatter symbols at once will trigger a bonus round which dishes out 15 free spins with a ‘bonus fish’ fixed on the third reel throughout, substituting for all other symbols around it. When the bonus fish creates a matching combination in the free spins round, the winning amount with be subject to a multiplier between 2X and 8X.
There isn’t anything particularly innovative about Crystal Waters and this isn’t a slot to suit the high-rolling, big bettors out there, even with the progressive jackpot. However, the lucrative bonus features add an exciting element to this Bitcoin game which will keep casual players entertained enough. USA-based players might be more drawn to this slot, since RTG developed games are some of the most popular for American slot spinners and Crystal Waters is one of the one of the only ocean-themed slots accessible in the country.
