How to play Shark Wash mobile slot

Open up the Shark Wash slot, and you’ll find a 5×4 reel, 1024 ways to win game with an underwater theme, a high 96.06% RTP and 5,000x your stake maximum win waiting to be scrubbed clean.

Relax Gaming presents the Shark Wash mobile slot where low-paying Aces, Clubs, Diamonds and Spades sponges blend in with the washing theme alongside four high-paying Shark Character symbols offering up the biggest winning combinations.

You’ll also find Avalanching Wins, Wild symbols that can add some extra multipliers, and Bonus Scatters, which can help transform your free spin wins.

Countdown Wilds with up to 5x Win Multiplier

Relax Gaming has added a Wild feature to this Shark Wash slot game to add to the excitement of the base game and free spins.

Here, wild symbols come with a counter between 1 & 5, which indicates how many tumbles they’ll stay when part of a winning combination. Every consecutive winning tumble reduces the countdown, which, if it reaches, will then increase a Wild Multiplier by 1x.

This is a feature which promises more than it actually rewards you within the base game, at least, as it’s in the free spins where the Countdown Wilds and Wild Meter come more into play.

Win up to 5,000x bet in the Shark Wash Free Spins

Finding 3 or more bonus scatters triggers the free spins bonus. It’s your typical scenario where the background of the slot changes, adding to the bonus game atmosphere.

You’ll find the same symbols across the five reels. However, whenever you add a 1x multiplier to the Wild Meter, it doesn’t reset on a non-winning spin.

The Meter can go up to a 5x multiplier, but more often than not, you’ll only reach a 2x or 3x, which still adds to creating some decent 50 – 100x bet wins.

You can buy the free spins bonus for 80x your current bet, but there are no guarantees you’ll win that back, so make sure you have the expendable cash, as Shark Wash is a high variance slot, after all.

Try more Relax Gaming slots with bigger wins, like the Money Train Origins Dream Drop slot or Dead Riders Trail game.

Shark Wash Review Conclusion

The Shark Wash slot on mobile is a fun enough game to play. However, the Wild feature doesn't show up often enough in the base game to excite even though you do get cascading wins.

The Free Spins are where you'll win the biggest wins but be sure to budget 50 - 100x base game spins to hit them, which is easily done thanks to a low 0.10 minimum bet.

It's not the best of the Relax Gaming slots you'll find online, and not one we'll come back to as many more underwater-themed slots offer more excitement and thrills, like the Release the Kraken 2 slot and Reef Raider game.

Take it for a spin at one of our best Relax Gaming casinos and see if this Shark Wash will help you clean out the casino of all its cash.
