With a 5x3 gaming grid and 20 paylines, Pandora's Box of Evil has a reasonably conventional layout. It is available in a variety of RTP configurations with a maximum return value of 96.2% and is also extremely volatile. Playable on desktops, mobile devices, and tablets, users can wager between 0.05 and 100 per turn, making it a particularly low-roller-friendly gambling machine.
All winning combinations pay from left to right, beginning with the initial reel. Pay tiles begin with 10 through Ace symbols that are worth 1.2 to 2 times the wager, followed by a creative collection of five high-paying character symbols that pay 5x to 8x the wager for a five-of-a-kind win. When wild symbols appear, they can substitute for standard paying icons to help complete successful paylines.
In a game like this, there must be a Pandora's Box-like device somewhere, and Mystery symbols are that device. Mystery symbols appear on each reel, transforming into Mystery Wilds or exposing scatter, Spirit of Hope, or pay symbols. Pay symbols that are revealed are always of the same variety. Prior to Mystery symbols revealing themselves, there is a possibility that they will be transformed into Mystery Wilds with a multiplier of x2, x3, x4, or x5 attached. When multiple Mystery Wilds contribute to a victory, the multiplier values are added prior to being applied.
When the Scatter of Hope is unveiled, a respin is triggered, which occurs after the current spin. All Mystery symbols, scatters, and Mystery Wilds are secured for the respin. During the respin, all locked Mystery symbols open to disclose a new random symbol.
At least three scatter symbols must be visible to trigger eight free plays. Throughout free spins, all Mystery symbols remain immobile until the feature's conclusion. If you land 1, 3, or 3 scatters during the feature, you will receive 2, 5, or 8 additional free spins, respectively.
