We always like an online slot with a story behind the action and Hidden, from Elk Studios, relates the expedition to Egypt of our intrepid explorer and his young sidekick in the early part of the 20th century – keep reading to find out how it all works.
Hidden is a five reel slot with four rows and 178 ways to win; each symbol is encased in blocks decorated with hieroglyphics and they fall into place with a satisfying sound. In the background there’s the entrance to a tomb beneath a pyramid guarded by god-like statues.
The high value symbols include the bearded explorer, the sidekick, a grinning camel and the Sphinx’ head; 10, J, Q, K and A make up the lower values.
The wild symbol is a glowing red and gold ‘Wild’ which will substitute for all others to help form winning combos except for the magnifying glass scatter icon.
Bonus Features
Treasure Room Free Spins
This is triggered by landing three of the magnifying glass scatter symbols anywhere on reels two, three and four; you’ll only receive five free spins but there’s a nice feature which can create some big wins.
One symbol is picked at random before the spins start and on each spin any of those symbols will turn themselves into large 2×2 icons with the original one in the top left; all other symbols will then fall away to allow 
new ones to drop in, hopefully with more of the chosen symbol and potentially a big win.
In addition any magnifying glass scatters landing during this round will award one extra spin.
Flashback Respins
This occurs at random in the base game and you will be awarded three free spins with one complete reel full of wild symbols.
Verdict
Hidden is a great game to play with some high quality graphics, a narrative to follow and two creative bonus features; the Treasure Room Free Spins are particularly well thought out and this game comes with an RTP of 96.30%.
