The theoretical payout percentage of Hidden is 96.3% – a great Return To Player. The variance is medium, which means that you can grab nice payouts, without your balance going down too much. The maximum win in a single spin is 215,000 coins.

All symbols come in stacked form and that means that there is considerable potential for big payouts. After all, you have 178 ways to win.

Logically, 5 of the same symbols do not pay extremely much. The premium symbols are Grandpa the Investigator, his sidekick, the Sphinx and the Camel. The elderly adventurer is the highest paying symbol: 5 of the same on a connected payline pays 10 x the total bet. The young researcher (perhaps it is his grandson) is also good for 5 x the bet. The camel and the sphinx have to make do with significantly less: 3 x and 2 x the total bet respectively.

The card symbols 10, J, Q, K and A traditionally function mainly as a filler and pay out just a little more or less than 1x your total bet. Although… a full house of Aces will give you 200x your total bet

The wild symbol replaces all other symbols with the exception of the scatter symbol, the magnifying glass.

Two fun and unique bonus features at Hidden

The Hidden slot machine has two original and especially nice bonus features. Both can also yield very nice prices.

The Treasure Room Free Spins bonus is activated as soon as 3 magnifying glasses appear on the screen. Not only do you win 5 free spins and 1 special symbol is designated. This special symbol expands when it appears on the screen. The other normal symbols disappear, and the special symbol remains. You will then receive a kind of super respin. Because the special symbol falls regularly, in practice you get around 8-9 free spins instead of the 5 you start with.

With a bit of luck, the special symbol can provide extremely large payouts, especially if you spin a few during the free spin, after which they expand.

We really like the Flashback Respins. This bonus feature is randomly activated for every spin. At first it looks like your connection has been lost because your screen seems messed up. But then it slowly dawns: something special is happening here! It turns out to be the Flashback Respins where you get 3 free spins with 1, 2 or 3 reels with full stacked wilds.

Can you get 2 or 3 reels completely wild? Then that camel with money comes in like that.

The maximum we have been able to grab so far is 2 reels with full wilds and that already resulted in a bonus of more than 100 x the bet. Never mind what happens when you get 3 reels completely wild!

You can also play with a fixed betting strategy with this Elk Studios video slot. There are 4 different betting strategies, and each strategy has its own risk profile. They listen to cool names like Booster, Jumper, Leveler and Optimiser

Choose the strategy that suits you best and the Hidden slot machine will do all the work for you.

Of course, you can switch the strategy on and off at any time during the game.
