What are Mystery Symbol slots?

Whether it’s Cascading Reels or Sticky Wilds, understanding how slot features work is important. It allows you to make the most of all your gaming opportunities, as well as picking out the games that are most likely to capture your attention.

Mystery Symbols are hidden when they first land on the reels, whether behind a ‘?’, a screen, or some other graphic themed according to the specific game. The big Reveal usually uncovers the same paytable symbol, which could add to Coin wins. Sometimes it’s free spins, multiplier values or some other game modifier that’s unlocked through the Mystery mechanic..

A quick straw poll of the TGTPlay team indicates that these are some of our favorite slots featuring Mystery Symbols, all of which come from the Pragmatic Play game design studios:

• Floating Dragon Megaways: A beautiful, Asian-themed slot, Floating Dragon Megaways features Cascading Reels, unlimited free spins and a Hold and Spin respin bonus. Lantern symbols transform into paytable icons during the base game, or Lady collector symbols during free spins. Don’t be fooled by the apparently calm and relaxed gameplay – this highly volatile slot has a max win potential of 20,000x.
• The Red Queen: With up to 243 Ways to Win, The Red Queen plays out on a 5 x 3 grid with an extra, locked reel known as the Queen Reel. Every space on the grid can split into up to 4 extra rows, giving variable win potential with every spin. Mystery symbols all transform into the same paytable icon, with respins, multipliers and free spins to look forward to.
• Zombie Circus: When they said the circus is dead, surely this isn’t what they meant? The Undead Circus has come to town, complete with a Wild brain-eating bear – although he only appears during free spins. Mystery presents can land on the 6 x 4 grid at any time during gameplay, revealing the same symbol randomly selected from the paytable – which could lead to enhanced wins.
