Hidden Slot

ELK Studio’s latest offering is a 5-reel, 178-payline Egyptian-themed online slot. Titled “Hidden”, this video slot is playable across all devices, starting from 20p up to £100 per spin. This video slot has its share of free spins, re-spins, expanding symbols, cascading wins, and sticky wilds.


Game Features and Symbols in Hidden Online Slot


The main protagonist in this online slot is Professor Taylor, a historian. Together with his nephew Benjamin, Professor Taylor takes players to the mystical Great Pyramids of Giza to search for the golden top stones. The graphics and animation are excellent. The audio is apt. The symbols include the standard playing cards 10, J, Q, K and A; Sphinxes, camels, Professor Taylor, and Benjamin. The wild is the WILD logo, which substitutes for all symbols except the scatter. The magnifying glass is the scatter symbol.


Flashback Re-Spins


The Hidden online slot has two bonus features. The first one is the Flashback re-spin, which is triggered randomly when playing any of the base game spin. In this feature, the sky becomes animated, offering the player a glimpse of Ancient Egypt. When reels 1, 2, or 3 are covered with sticky wilds, the player gets three free re-spins.


Treasure Room Free Spins


Treasure Room Free Spins is the main bonus feature, made available when a player lands 3 or more scatters anywhere on the reels. When this happens, the player gets 5 free spins. At the same time, the machine automatically chooses which symbol on the reels will become the expanding symbol.


The expanding symbol will expand to a 2×2 block of the particular symbol when it appears during the free spin event. A second symbol drop will happen as all other symbols on the reels disappear. When this happens, it is possible for more expanding symbols to land on the reels. For every scatter, an additional free spin is given. A higher value symbol is needed for bigger cash out.




The base game and the two bonus features promise huge winnings for the player. Though the Flashback Re-spins offers a possibility, the bigger winnings will come in the Treasure Room Free Spins bonus feature, thanks to the expanding symbols and symbol drops.
