Players will be transported to Egypt in this exciting slot game, and hopefully you can take the heat as you spin its reels for big cash wins! Behind your reels, you will see the ancient pyramids looming, while the symbols on your reels tie in perfectly with the rest of this theme. Expect to find camels, explorers, sidekicks, Sphinx's and card playing symbols which are the lower value symbols. These symbols are encased in blocks and are decorated with beautiful hieroglyphics.

Wild Symbol:

Wild symbols are the centrepiece of most slot games, and Hidden is no different! The wild symbol is certainly eye-catching with a glowing red and gold theme and its job, if you are not familiar with it already, is to replace the other symbols on your reels to create lots of winning combos. Another important symbol in the slot game Hidden is the scatter symbol, and this is the magnifying glass. This symbol also cannot be replaced by the wild symbol and it will trigger the free spins bonus round below when three of them land on the 2nd, 3rd and 4th reels.

Treasure Room Free Spins:

Once this round has been triggered, players will receive 5 free spins. A symbol will be chosen at random before your spins start and this symbol is important as each time you spin, if this symbol appears on your reels they will become 2x2 icons. The chosen symbol sits to the top left while the other three symbols fall away and are replaced by new symbols which players will be hoping is more of the randomly picked symbol as this will award you even bigger cash wins! What's more, for each extra scatter symbol you land during this round, you will be awarded another free spin!

Flashback Respins:

This extra bonus feature is another way to grab yourself more free spins! You'll never know when it will appear as it is randomly triggered but when it does during the base game, you will receive 3 free spins. This round can be highly lucrative as players will also have on reel turned completely wild for the duration of these free spins.
