Mystery Symbols

A mystery symbol looks identical to its siblings until it opens: after the reels stop, it turns into something specific. Usually every mystery on the screen becomes the same picture, so a rare lucky reveal can flood the grid with a premium symbol in several places at once.

Red Tiger’s Mystery Reels (14 June 2017) builds the whole game on a single mark: it clones across the reels and then becomes a paying symbol or opens a bonus wheel. Layout: 5×3, 20 lines; 96.24% RTP, high volatility, a 4,991x cap. The rules take a minute to learn, and the long silences between wins take longer to get used to. Its older sibling Dragon’s Luck (13 April 2016) uses the mystery as a coin: a winning spin turns up only 11.94% of the time, though a repeated reveal makes the sums weighty.

Stacks and countdowns

Push Gaming’s Razor Shark (3 September 2019) uses Mystery Stacks: columns of four seaweed symbols slide down the reels and can turn into mini-reels paying instant multipliers. With 96.70% RTP the game promises up to 50,000x. The studio’s later Mystery Museum (27 August 2020) is tamer: three or more stacks cover their reels completely, the game picks one ordinary symbol and every stack turns into it. Its ceiling is 17,500x.

Relax Gaming’s Hellcatraz (5 May 2020) shows each mystery symbol as a countdown, on a 6×6 grid with 46,656 ways and RTP of 96.46% in Lockdown and 96.30% in Mixed. When the key counter reaches 2,000, super free spins begin, and the cap is 51,843x. In its Top Dawg$ (2 June 2021) the Mystery Respins reveal every mystery as the same symbol, with a 25,000x cap.

In Thunderkick’s Pink Elephants 2 (6 May 2020) a Mystery Scatter can drop one to five extra scatters on any base spin, and its only job is to help you collect a trigger’s worth. The highest RTP among the mysteries belongs to NetEnt’s Mega Joker (1 October 2008): 99%, with the Joker itself setting the sum of a mystery win.

Pay attention to when the reveal happens: before pay-out, as in Mystery Reels, or in a dedicated mode. The first kind is quiet and sharp, the second more patient. How volatility shapes those pauses is unpacked in the guide to low, medium and high volatility.
