About Hidden

ELK Studios are the developers behind the Hidden slot machine, which features a rather endearing 5-reel, 178-line gaming platform which we haven’t really seen before. The basic premise behind the slot is that of Ancient Egypt. A sort of exploration and adventure theme is up for grabs with Hidden, which features a comedic and quirky take on this popular slot theme. Hidden is remarkably cheap given how many paylines you get to play with. Players can expect to be able to spin the reels of this slot for as little as 20p a game, whilst even max bets cost just £100 a pop. Non-progressive prizes worth 3,000 coins don’t hurt one bit, either.

Special features

Wild symbols are naturally present in the Hidden slot. They are pretty basic and can substitute for all other symbols in the game save for scatter icons. Those scatters appear as magnifying glass symbols.

As good as wilds are, they don’t come close to the entertainment had by the randomly triggered bonus in this game. At any point in gameplay, a Flashback Re-spins bonus may be triggered. When it is, players can pocket 3 free re-spins, with between 1 and 3 reels becoming sticky and expanding wilds.

Bonus features

There is also a proper bonus in this slot. The Treasure Room free spins bonus round is activated when 3 or more magnifying glass scatter icons appear on the reels. In the feature, players will start with 5 free games. A symbol will be chosen at random to appear as an expanding 2x2 icon in the round, whilst a cascading reels feature allows you to win multiple times with your free spins. This is a handy little feature to bag big wins with, particularly if you 2x2 colossal symbols plays a part in those wins.


Hidden is not your ordinary Ancient Egyptian themed slot. It has a bit of light-hearted relief to it, and players are going to find it immensely cheap to play, which is never a bad thing. Graphically, Hidden is a little under-par, but we can get past that given the quality of the special features.
