Wonders of the Deep Slots

The oceans cover most of our planet, and most of them remained unexplored. Who knows what sorts of treasures have sunk into the abyss over the ages?

Wonders of the Deep is a video slot game by Gamesys that is designed to take players on an underwater adventure to explore the final frontier on Earth: the depths of our own oceans. No diving gear is required here, all you need is a working computer, a sense of adventure, a little courage and some luck on top to win the big cash prizes hidden on the reels of the game.

Find out more about Wonders of the Deep by reading our full review of the game, starting right now with a closer look at the game universe itself.

Mysterious Sunken Ruins

The reels might be occupying most of the screen space in Wonders of the Deep, there is still some space left all around to give players an eye of where they are standing.

Or floating, to be more accurate. The reels are framed by two marble columns, relics of an ancient civilisation long extinct, sunken under tons of salty water. The surface is still visible up above, with the sunlight shining through it. You will also notice some coral reefs and plenty of seaweed all over the sea bed.

Wonders of the Deep stays quite classic and gives player an underwater game universe with plenty of details to enjoy, and really beautiful light effects. All in all, a good start for this Gamesys creation, but let’s see if the quality holds when we examine the basic game rules in the next section.

Take a Deep Breath and Dive Right In

Wonders of the Deep might be taking place underwater, it still follows the usual rules that any land-based slot game features.

The game matrix is waterproof and contains 5 reels with enough space for three symbols on each. With 15 paylines available, you should have plenty of opportunities to land several winning combinations. Each time you do so, a cash prize corresponding to the nature of the symbols involved and your wager is awarded. Use the command bar located below the reels to adjust your settings before spinning the reels.

Bigger bets mean bigger rewards down the line, so try putting a little extra on the table if you can. And should you feel like speeding up the game a little, simply turn on the autospin mode. The reels will then revolve on their own for as long as you like, placing several bets in a row without you having to do anything else than cross your fingers and watch your winnings pile up gradually.

Underwater Mutations

Wonders of the Deep features 9 different reel symbols, all of them boasting an original design to match the theme of the game.

Even the classic card icons have morphed into shellfish or buoys to adapt to their new salty surroundings. Ranging from number 10 to the Ace, these first few symbols are both the most common of the game and also the least rewarding. Quantity will have to trump quality for now.

The starfish, jellyfish, seahorse and sea turtle make up the rest of the basic menu. These animals might be a little more challenging to spot on the reels, but they can multiply your initial bet hundreds of time with their long combinations - the turtle is especially valuable, with a x1,000 cash prize for every 5-symbol combination.

Three More Chances to Win Big

There are three more special symbols hidden in the reels of Wonders of the Deep, starting with a dolphin that acts as the wild card of the game. Use it to replace any basic symbol to complete extra winning combinations, or line up several of them for extra big wins: 5 dolphins aligned are worth a x10,000 cash prize.

The puffer fish is yet another special symbol, a scatter to be precise. Wherever it lands on the screen, this symbol will trigger a cash prize for the lucky player.

Finally, three shells lined up on a payline initiate the bonus round of the game. Pick a shell to win free spins, and a second to land a multiplier. Start spinning the reels free of charge and hope for many wins.

Plenty of Fish in the Sea

Wonders of the Deep is a classic slot game with a generous selection of bonus features and plenty of free spins waiting to be triggered. The strongest points of the game are the generous rewards available, even during the base game, and the easy gameplay.
