Hidden RTP and Volatility

6.7 
Hidden has an RTP of 96.3% and is a medium-high variance slot.
The Return to Player percentage of the slot is around the industry average. This ensures the best profits on your winnings. Also, the medium-high variance gives an indication that the slot can bring good wins on your stakes. But don’t expect recurring wins during the game.

Theme

6.9 

The Hidden slot takes the theme of ancient Egyptian and the search for treasures. Elk Studios has developed a storyline featuring Professor Taylor and his nephew Benjamin who are on a venture to explore the treasures of the pyramid.

They leave the rainy London to solve the massive mystery behind the missing golden top-stones of the Great Pyramid. Were these top-stones always available or buried somewhere? Well, that is the Hidden mystery that we solve by playing the game!

The background of the slot shows the pyramids and the figures of Egyptian Gods standing guard to them. The game graphics are superbly developed and offer a high-quality experience on all the devices you play.

There are 9 regular symbols in the Hidden slot. The high valued icons of the game are Professor Taylor, his nephew Benjamin, Camel, and the face of the Sphinx. The Professor Taylor symbol is the highest-paying icon in the game.

The low-valued icons in the game are card suit symbols. You will find Ace, King, Queen, Jack and 10. There is one special symbol of the wild. However, there are different bonus elements to explore while you play the slot.

The wild symbol lands only on the 2nd, 3rd and 4th reels. It can substitute for all symbols except the magnifier glass symbol, the Scatter, that triggers free spins.

Bonus Rounds & Free Spins

7 

Hidden has some special bonus elements to play. These include:

Treasure Room Free Spins Bonus Games

The magnifying glass represents the scatter symbol here. It can appear on the 2nd, 3rd and 4th reels only. Land 3 scatter symbols on the reels to trigger the 5 free spin Bonus rounds. These are known as Treasure Room Free Spins bonus games.

Free spins can be retriggered during the bonus rounds. For every magnifying glass that lands in the bonus mode, players get 1 extra free spin.

When the Bonus mode begins, one expanding symbol is randomly picked from the regular icons. The expansion of the symbols takes place after the payout. All the non-expanding symbols are removed from the reels. The expanded symbols fall down on the reels, and new wins are created. Accordingly, the new wins get paid before the start of the next free spin rounds.

Flashback Respins

Flashback Respins are randomly activated in between the normal spins. The middle reels can get covered by sticky Wilds and stay there up to 3 spins.

Flashback Respins cannot be retriggered within the same spin. Any additional wild symbols that land during the Respin rounds won’t be sticky.
