With at RTP of 96.3%, Hidden is a medium-high variance video slot, that unfortunately doesn’t have progressive jackpot. Winning a round or two in the Treasure Room Free Spins bonus game, however, could still land you with winnings of up to 215,000 coins – we knew there was gold somewhere in Ancient Egypt!

Special Features and Bonuses:

There are a couple of cool features worth mentioning on the game, because as we’ve mentioned, there’s a chance of winning up to 215,000 coins!  

  • Flashback Respins Feature: this feature is randomly triggered when in the main game and it’s one that leads to quite a lot of winnings! Sticky Wilds cover somewhere between 1 and 3 of the central reels during the free respins. Your flashback adventure is accompanied with fun music and flashing fiery Wilds.
  • Treasure Room Free Spins Feature: this feature comes about when you’ve landed 3 or more magnifying glass Scatter symbols. The magnifying glasses open up and lead you through a secret tunnel to the Treasure Room. There, you’ll be awarded with 5 Free Spins where one of the symbols will be an expanding Wild. The expanding wild will become a 2×2 block whenever landed and the other tiles on the board will be respun to give you even more chances of winning. On top of that, with every new magnifying glass you land in the Treasure Room, you get more Free Spins! Overall, this cool feature can result in winnings 1250x your wager!

Graphics and Sounds:

The imagery on Hidden is really appealing: quirky, well-drawn characters, hieroglyphic backed letter symbols and a nice attention to detail.

There’s no background music on the base game, which is rather refreshing. Instead you can enjoy the sound of the desert winds and the shuffling of game tiles. When you do stumble upon a bonus feature, there is fun, Middle Eastern-style music to accompany your the excitement of winning.


Hidden is a fun slot that takes you on an adventure through a unique part of history. It’s well-designed video slot, with cool features, nice details, and a fun handful of bonuses… give it a go and see if you can find the gold-laden Treasure Room!
