Find out all you need to know about this exciting slot title with our Skeleton Key slot review.
Game overview
Skeleton Key features a 5×3-reel grid that can expand, giving players the chance to spin on a 5×6-reel grid when fully expanded (where symbols are piled six-high.) The reels offer between 243 and 7,776 ways to win – depending on the number in play – and feature 14 spooky symbols including a wild, a scatter and a mystery symbol.
There are plenty of bonus features on this captivating online casino slot, complementing the 96% RTP (return to player,) which is pretty standard for modern online slots. With a medium-to-high volatility, players may have to wait a while between wins, however, they should be well worth the wait.
How to play
Start off by reviewing the game rules and paytable, which can be found at the top of the game screen. Here, you can also adjust the volume settings.
Next, set your bet amount. The total bet, coin value and balance can be found to the left of the reels. You can modify your total bet (which will automatically adjust your coin value) by selecting the “+” and “-” buttons – choose from $0.10 to $300 per spin.
If you prefer smooth, uninterrupted gameplay, select the autospin option just above the Spin button to the right of the screen, and choose between 10 and 50 autospins. The autospins will stop any time you land a winning combination or a bonus round is triggered.
Once you’ve adjusted your game settings to your liking, it’s time to get spinning! Select the large arrow button to the right of the reels to enjoy watching the action unfold.
While you’re spinning the reels, you’ll notice that they expand whenever and wherever a key symbol lands. When this happens, you’ll be able to see the number of ways to win to the left of the reels. Find more on the bonus features in the section below.
Graphics
IGT has designed a mysterious and intriguing slot game with impressive graphics and immersive gameplay. Skeleton Key is set in a cave filled with piles of gold, jewels and treasure chests. The reels are presented in the cave opening against a misty dark blue background, and feature low-paying J to A royal playing cards, alongside three gold-encrusted purple, green and red gemstones. The highest-paying symbols include a book of spells, a chalice and a treasure chest. The wild symbol, which substitutes for all symbols except the scatter and bonus symbols, appears as “WILD,” while the “BONUS” padlock is the scatter. Land the skeleton key on any of the reels to unlock (literally) the expanding-reels feature.
The cartoon-style graphics and animations in Skeleton Key are bold and colorful, which renders well on both desktop and smaller mobile devices. The locked reels are hidden by a lively green mist, adding to the spooky atmosphere of the game. With so many bonus features, the reels really come to life and the spirited soundtrack makes for a captivating quest.
Features
Expanding reels
The name of the game is Skeleton Key, and for good reason. When a skeleton key lands on any of the reels in view, that particular reel will expand to offer more symbols in play (up to 6,) and increase the winning potential. With each spin thereafter, the “unlocked” reel will shrink by one symbol until it’s back to its former size… unless another key lands on it.
Should you land keys on all the reels simultaneously, you can unlock the full grid, along with 7,776 ways to win!
Free spins
Trigger the free spins bonus round by landing 3 or more padlock scatter symbols on any of the reels. Three of these symbols will award 10 free spins, and each additional symbol will score you an additional 10 spins. Extra spins can be triggered during the bonus round by landing 2 or more scatters, and the reel-expansion feature is also active during this round (the mystery symbol will transform into a key here, lending to more ways to win all round), making it the most lucrative round in the game. During free spins, the key symbol acts as a multiplier as well.
Mystery symbol
Look for the question mark on your reels to reap the rewards of the mystery symbol. When you land any mystery symbols on the reels, they will all transform into one of the paying symbols, increasing your chance of forming a winning combination.
Bonuses and jackpots
Though Skeleton Key isn’t a jackpot slot, it’s great fun to play, and the incredibly high number of ways to win and max win potential of 83,333x the bet make it just as worthwhile trying your luck. This max win can only be achieved during a free spins bonus round, where there are multipliers at play. During the base game, you get the chance to win up to 10x your stake on each spin.
