How to Play

Hidden is fairly easy to play, apart from a few fiddly settings you should know about before starting.

  • First, you need to set your total bet. Click on the stack of coins with a ‘+’ symbol on the bottom left-hand side of the screen. Choose what you’d like to bet – from 10p (minimum bet) to £50 (maximum bet) a spin.
  • Hidden includes a nice little extra – the Betting Strategies option. ELK Studios includes some helpful advice on how to use 4 different betting strategies, which you can select from the ‘Total Bet’ screen. These range between ‘casual player’ to ‘high roller’: Optimizer, Leveller, Booster and Jumper. If you have the time, definitely have a play around with these.
  • There’s also the autospin option – you can set either 10, 25, 50 or 100 autospin rounds. Or, simply hold down the Play button, for it to begin autoplaying automatically.
  • Then: click the Play button, and get spinning!

Special Features and Bonuses

There are two noteworthy extra features on offer in Hidden:

  • Flashback Respins: randomly triggered in the main game, you’ll suddenly see the skies animate and change into the skies of Ancient Egypt – which is quie a sight to behold! You’ll then be given 3 free respins, with sticky Wilds covering between 1-3 of the central reels.
  • Treasure Room Free Spins: this is the biggie! If you’re lucky enough to spin 3 or more magnifying glass Scatter symbols on the reels, you’ll receive 5 Free Spins, with one of the symbols turning into an expanding Wild. During a Free Spin round, this expand wild will become a 2×2 block, with the other symbols disappearing, allowing more symbols to drop into their places. This also allows more 2×2 blocks to happen. Every time you spin a magnifying glass in the Free Spins round, you’ll trigger more Free Spins. It could even lead to x2150 your stake!

Graphics and Sounds

The graphics are unlike anything you’ve ever seen, much like ELK Studios’ other slot games. When you spin, the reels won’t actually spin – they drop to the bottom of the screen…and more symbols (with a background of parchment) will drop from the sky. When you spin a winning combination or bonus feature, the non-winning combinations symbols flash on and off the screen, with the winning combination receiving a lovely gold highlight.

We have to give a shout out to ELK Studios for their exciting soundtrack, on Hidden and their other slots too. As the symbols fall, you’ll hear the sounds of falling bricks, thudding to the floor. When you spin a winning combination, you’ll hear some mysterious, Ancient-Egypt/Middle Eastern tunes playing. While you’re waiting to spin, you’ll hear the rush of the wind, a few Middle Eastern sounding notes being played, and a bird of prey screeching. During the Free Spins round, you’ll hear an extended version of the Middle Eastern theme from the reels. It’s all very atmospheric…and mesmerising.


We really, really love this slot. The soundtrack, the bonus features, the gorgeously detailed graphics, the rspins, the 198 paylines…need we say any more?

Play Hidden by ELK Studios – we’re almost certain any and every slot player, both new and experienced, will have a fabulous time.
