Graphics and Theme

Ghostly treasure troves are nothing new to the thematic world of online slot games. IGT however, have reinvigorated the genre with this latest creation. It’s fun graphics, and simple yet effective visual components are real treat for the player. Skeleton Key’s background is a dark underground space littered with treasure chests, all bearing a skull symbol on them somewhere. The middle of the screen is taken up by the playing reels which are superimposed onto a foreboding looking lake. The board is made up of floating symbols, with the unlocked reels sitting atop the regular playing board, wreathed in wraithlike smoke. The smoke is removed as you unlock these extra reels.  Normal symbols are represented by gold-fringed letters, whiles special symbols take the form of a chalice, gemstones and a padlock bonus symbols. The music is a fast-paced wind instrument piece, designed to build tension in the game.

The base game of Skeleton Key as you will notice when starting is played on a 5×3 grid.  However, as has been mentioned, there are expanding reels in this game which form the basis for the bonus play. To unlock these supplementary reels, players must land key symbols somewhere on the reels. The expandable bonus reel above the reel on which you land a key will be opened (you will notice that the smoke clears from the corresponding symbols) meaning three more symbols for that reel will be usable, increasing the available pay lines.

After this sequence, the key is then removed from the grid, and new symbols will fill the spaces below. If you expand all the reels, the grid reaches a maximum size of 5×6, giving the player a maximum of 7,776 way to win. However, for each spin which does not land a key, the grid will shrink by one symbol and eventually end up back in its 5×3 format.

Mystery symbols are in play in Skeleton Key and are represented by boxes with question marks on them. These can randomly land on any reel. When they do, they will transform randomly into any type of symbol, meaning they could trigger wins.

Skeleton Key also has an impressive Free Spins round. Players can trigger it by landing three or more of the padlock symbols on the board simultaneously anywhere on the reels. The number of scatters landed translates into the number of free spins which you are awarded to take into this bonus round.

• 3 scatters = 10 free spins.
• 4 scatters = 20 free spins.
• 5 scatters= 30 free spins.

Once within the Free Spins round, you can keep adding to your free spins total by landing additional scatters. Landing 2 scatters adds two free spins to your total. Landing 3,4 or 5 follow the same values as above.

When you are in the Free Spins round, a progressive multiplier will be applied to the wins that you achieve. At the start of the feature, the multiplier is 1x, yet for each skeleton key landed, the multiplier will grow by 1x.  Mystery symbols (the question mark boxes) now also can reveal skeleton keys, giving you a greater chance of increasing your multiplier and the ability to expand the reels.

Wild symbols are also in play and replace any other symbol on the reels bar the scatter to help form more wins.
