World Water Day is observed every year on 22 March. Its purpose is to shine a light on how important freshwater is in our daily lives. It’s also an opportunity to promote sustainable management of our water resources. This important day is linked to the United Nation’s sixth Sustainable Development Goal, which is water and sanitation for all by 2030.

There are many ways you can take action on this important day. Visit the World Water Day website for more information, watch a documentary about the issues involved or simply practice using water responsibly at home. We’ve also put together a list of our best online slots with a water theme that you can play at our free bonus, no deposit UK casino. Let’s get started.

Majestic Sea 2

Start playing mobile slots with no deposit by trying your hand at Majestic Sea 2. Developed by High 5 Games, this five-reel, 40-payline slot offers potential prizes that could amount to 1,000x your stake! Are you brave enough to dive into the ocean’s depths to search for treasure among great white sharks, dolphins, stingrays, turtles and jellyfish that swim between the stones and broken columns of a ruined temple littering the seabed?

The graphics of this game are excellent, bringing an underwater world to life and adding to the excitement of perhaps discovering the pearl that triggers the main bonus feature of this slot. Land this treasure on each of the three middle reels to be rewarded with six free spins. The pearl, which locks into place when landed, can transform into doubles and triples on subsequent free spins, leading to potentially sizeable wins!

Look out for the fan coral wild in single, double and triple variations, which can help you make winning combinations by standing in for all the other symbols except the pearl.

No doubt about it, playing Majestic Sea 2 at our no deposit free spins mobile casino is an immersive experience that’s well worth dipping your toe into.

Nemo’s Voyage

Fancy a trip deep into the ocean aboard Captain Nemo’s submarine? Join the adventure to haul in the priceless treasures of lost civilisations that are up for grabs in dark, unchartered waters.

Nemo’s Voyage by WMS has five reels and 40 paylines, and can be played from 40p to ￡200 a spin. The game is rich in under-the-sea symbols – whales, hammerhead sharks, mysterious deep-sea fish, the Nautilus submarine and a giant squid that appears at random to wrap its tentacles around the reel and tear off a number of symbols. These symbols transform into pressurised wilds that stay put throughout the free spins feature, leading to some potentially big wins.

Part of the no deposit spins offering at The Phone Casino, Nemo’s Voyage adds to the usual excitement of playing slots with a unique wild feature represented by a depth metre that awards you with wilds, 2x wilds, 3x wilds, pressurised wilds, stacked wilds and wild reels. Each time you spin the reels, the Nautilus moves down the depth metre and when it passes a certain point, a ‘lock’ closes and initiates a wild feature that continues until you’re lucky enough to pass another ‘lock’. To add to the excitement, there is a pressure gauge at the top of the depth metre with a needle that moves to the right as the Nautilus descends.

If you haven’t yet taken the plunge, a trip to the bottom of the ocean on Nemo’s Voyage is high adventure indeed!

Purrates of the Catibbean

As the name suggests, you’re in for plenty of fun and games when you play Purrates of the Catibbean at our no deposit mobile casino! Who would have thought cute cats and pirate adventures could combine so seamlessly, but they do. So, hoist the sails me matey and take to the seven seas with this superb mobile slot by High 5 Games.

You can play for two to 250 coins over three reels and 50 paylines with the chance to loot the progressive jackpot!

High 5 Games’ exceptional 3D graphics include a background of palm trees, a pirate ship and a sea so beautifully rendered you can practically taste the salt on your tongue! But the guy who steals the show is undoubtedly the pirate captain, who happens to be a particularly cute tomcat with flowing ginger hair. The soundtrack definitely does its bit to add to the game’s appeal, with a cacophony of meows set to jaunty music.

With several modifier-rich bonus features, including free spins and Lasting Loot Wilds, you’ll be itching to take the high seas, even if you’re a landlubber!

Sam on the Beach

If you prefer to admire the water from afar, you can stay on the beach with Sam thanks to ELK Studios’ engaging five-reel, 243-ways-to-win slot called Sam on the Beach. You’re invited to tag along with Sam as he takes his family (daughter Maggie, wife Sandra and older brother Ted) on a holiday to the Caribbean.

Chill to the soft sounds of the Caribbean islands as you spin this feature-packed game that includes the Beach Memories Respin, triggered when you land all four family members on the same row. Next, you’re given a free respin that transforms Sam and his family into sticky wilds. There’s also a free spins bonus feature that activates if you get three, four or five treasure ship bell symbols on the reels. This gives you five, 10 or 15 free spins, respectively.

There’s no shortage of treats on this family adventure. Each family member has a feature that can be triggered when they land during a free spins bonus round. These are:

Sticky Wild – Sam lands to help you along with sticky wilds.

Sticky Multiplier – Ted appears to pass along 2x or 3x multipliers.

Bonus Multiplier – Sandra shows up on the reels to increase the multiplier by 1x up to 10x.

Imploding Symbols – Maggie sweeps the low-value symbols from the reels.

With so much excitement to be had on the reels, we know you’re impatient to test the waters with this appealing slot on World Water Day!
