Mystery Symbols Slots
Mystery symbols hide what they are until a reveal turns them into one thing. Diner Dogs flips crew symbols into mysteries and reveals them as multiplier wilds in the free spins.
A mystery symbol hides what it is until the game reveals it. The reveal can turn a flat-looking spin into a winning one. The rules of each game decide what the symbols can become and when.
How Diner Dogs uses it
In Diner Dogs, a win with a crew symbol flips every matching character on the grid into a Mystery Symbol. The reveals can become 5x wilds inside the Golden Frames that natural wilds leave behind. Frames that come from mystery reveals are silver and carry 2x or 3x.
What to check
Ask what the reveal can turn into and how many symbols it touches. In Diner Dogs, the answer sits in the free spins. If you want the cascade side of the game, read the page for Tumble & Cascading Reels.
