Hidden Slot bonus, free spins & jackpot

Discover the Treasure Room Free Spins feature with the help of the bearded explorer and his trusty sidekick. To trigger this bonus feature, you will have to land three magnifying glass scatter symbols on reels two, three and four and Hidden slot will award you 5 extra spins. Before the start of the spins, a symbol is randomly selected to expand to a 2 x 2 symbol when the selection appears on the reels. If this becomes part of a winning combo, after payout, it will explode and allow more symbols to drop down to form other combinations. Every scatter appearing in the feature will add one extra spin.

On top of the free spins feature in Hidden, there is a wild icon and a random bonus feature that can be triggered during the base game. The wild substitutes for all other symbols but the scatter. When the Flashback Respins bonus feature occurs three of the middle reels become full of wilds; sticky wilds, as they remain on there for three spins, combine that with the 178 ways-to-win, and the game thrill factor increases. In addition to all this, you can also choose to activate one of four betting strategies to help you discover the 215,000 coins jackpot.
