Hidden is an Ancient Egyptian exploration themed slot machine game, and one which centres on the tale of Professor Taylor, and his protege.

Hidden is quite an original and inventive slot machine, with a unique payline structure and stunning 3D graphics. The slot has been designed and developed by ELK Studios and features a block structure, with far less predictable imagery on its reels than most of the other, more mainstream Ancient Egyptian slot machine games.

Imagery includes the Great Sphinx, Professor Taylor and his protege themselves, smiling camels, maps and magnifying glasses, as well as funky looking high playing card symbols.


ELK Studios are really coming on strong of late, especially when it comes to the graphical quality of their newest slot machines.

Despite barely being a few years old, these casino software providers have managed to jump up the pyramid of casino software providers to dish out what is arguably a cracking slot machine game.

Originality seems to be one of their strong suits, and in a casino world where many slots contain the same theme, features and images, that is much appreciated.

How to play it

Hidden features a total of 5 reels and 178 paylines. This 178 ways to win payline structure is pretty firmly planted into the slot, so players aren’t going to be able to tinker with the number of lines available.

They can, however, use any number of the many betting strategies which ELK Studios incorporates into its games, to place bets which range from a floor of 20p per spin, right up to a capped maximum bet of £100 per spin.

Special features

Flashback Re-spins: There are only two special features in Hidden. The first of these is the Flashback Re-spins bonus. It can be triggered entirely at random in the base game. When it is, players will pocket a total of 3 free re-spins. During this bonus, wilds appear. Wilds can only appear in bonus rounds but can cover 1, 2 or 3 central reels in this re-spins feature.

Treasure Room free spins: The other bonus in Hidden is the Treasure Room free spins feature. This bonus is played when 3 or more magnifying glass symbols appear anywhere on the screen. At this juncture, players will pocket a total of 5 free spins. During the bonus, one of the symbols in the game will be randomly chosen as an expanding icon (2×2 colossal symbol) for the duration of the bonus round.

Maximum pay-outs

Hidden claims to be able to offer players the chance to win as much as 215,000 coins in total.

As for the best-paying symbol in the slot, that is easily Professor Taylor himself, who can dish out wins worth 1,000 coins when 5 appear on any line in the game. The more lines you land this winning combo on, the larger the prizes will be.


Hidden has nifty features which haven’t really been seen in other Ancient Egyptian themed slots before, and the presence of creative imagery gives the whole Ancient Egyptian slot genre a new, distinct flavour which is much appreciated.
