Dive down to the depths of the sea bed and try and discover hidden ocean treasure in Deep Riches. Powered by Core Gaming, this 5 reel, 20 payline slot comes with special symbols that float across the reels with each spin as well as a free spins round with floating wilds that lock in place when they reach reel 1. Play from between 20p and £100 per spin.

Deep Riches is a very well-constructed slot as far as design is concerned – the reels are set within the sunken pillars of a lost, Atlantis-style city and there’s an assortment of plankton and sea creatures bobbing along the ocean floor. Everything is bright, glossy and super sharp.

The symbols float up bubble style onto the reels. They include A to 10 playing cards as well as brightly coloured, gemstone sea objects. You’ll see turtles and crabs as well as a trident. The purple star is the most rewarding symbol – land 5 of these on a payline and you’ll win 25 times your total stake. That amount is also on offer if you land 5 wilds on a line – the wild replaces all other symbols bar the bonus.

On any spin, random symbols can float onto the reels from the right-hand side – this is known as the Special Floating Symbols feature. These then float across, walking wild style, 1 reel at a time until they drop off the leftmost reel. If the Wild Water feature randomly becomes active, these special floating symbols will be wilds, boosting your chances of landing a winning combination.

Deep Riches comes with a Reef Bonus feature – to trigger it, you’ll need to land 3 or more of the pearl scatter anywhere on the reels. Choose from 1 of the 3 shells shown to reveal how many free spins you’ve been awarded – I’ve had up to 10 before.

These free spins play out on a new reel set closer to the surface of the water. To the left of the reels is a giant net – wilds will float across the reels on each free spin. Rather than dropping off the reels when they reach the leftmost reel, the net holds them in place for the remainder of the feature. Other wilds can then fall next to them on adjacent reels to create wild clusters.

With its lovely visuals and gentle soundtrack, Deep Riches has a tranquil feel – we landed the free spins regularly and found the variance to be in the middle. The sea bed is a popular hunting ground for slots players. This offering from Core Gaming is a simple but very playable ocean adventure and certainly worth a closer look. I also recommend you try the volatile Lord of the Ocean by Novomatic and IGT’s King of Atlantis.
