Skeleton Key - Slot Outlook

The term 'Skeleton Key' is known as a type of master key used to unlock numerous locks. Such keys are made in a special way to fit various locks, with a mostly removed center part and only essential parts remaining to pass by the lock wards. Here, Skeleton Keys are used to unlocking the grid and winning wondrous prizes.

Set in an illuminated cave, where piles of gold coins and treasure chests are scattered around the place, the view is dominated by a 5x3 grid with 243 ways to play. It's partially locked at the beginning, though, it expands up to a massive 5x6 game area, producing 7,776 paylines during the bonus features.

Playable on any device, Skeleton Key offers a pretty wide betting range of 0.1$ to 300$ per spin, which will appeal to both high-rollers and less risky players. The slot is powered by a medium-high volatile math model and comes with a solid RTP of 96%, which is on an average level within the industry.

The symbol collection includes 10 regular symbols, split into highs and lows. The pay symbols start at the lower end with A-J royals. They are followed by green, red, and purple gems, alongside spellbooks, cups, and treasure chests. At least 3 matching symbols on a line starting from the leftmost reel are required to score a win, while the top-paying symbol needs only two. Full combos are achieved by landing 5 instances of the same symbol on a payline, with the most rewarding paying 50x of the bet for a 5-of-a-kind combo.

Skeleton Key - Bonus Features

The expanding reels feature plays a central role in the gameplay. The session kicks off on a common 5x3 layout, and whenever a key symbol land anywhere in view, it unlocks the respective reel and reveals 3 more symbol positions on top of the main reel set, increasing the number of paylines. The key is then removed, and new symbols tumble down and fill empty spaces. The grid maxes out at 5x6 size, producing 7,776 ways to play. However, the grid's size is reduced by 1 symbol position with each next spin in case keys do not appear until it reaches the initial 5x3 format.

The question mark tiles are Mystery Symbols here, which can randomly land on the reels on any spin. Whenever they do, they transform into the same instance of a randomly chosen symbol.

Anyway, truly impressive rewards can be claimed within the Free Spins feature. It's triggered when 3 or more padlock Scatter symbols appear simultaneously anywhere on the grid, with 3, 4, and 5 Scatters award 10, 20, and 30 spins to start respectively. The feature can also be extended by landing at least 2 Scatter symbols to get +2 additional Free Spins, or 3, 4, or 5 symbols to get 10, 20, and 30 additional spins respectively.

Once the bonus game is activated, the progressive multiplier comes into play.

Skeleton Key - Slot Verdict

With minimal features and simple cartoonish design, Skeleton Key still manages to stick out from the crowd thanks to its incredible winning potential. Even though you won't see anything innovative here, the 83,333x max win capability sounds like a solid reason why you should give it a try.
