Our editorial rating for slots, computed the same way for every game from the figures on this page: the return (its top and its lowest configuration), the top win, whether that win rewards the game's volatility, the depth of its features, and how much of its data the studio publishes itself. Where a figure is not available, that part is left out rather than guessed. It rates the game, not a casino or the studio, and it is not a prediction of what you will win.
What the figures say about Wicked Grin.
Our reading
Wicked Grin is listed in 4 return configurations, from 96.27% down to 86.28%. Hacksaw Gaming publishes 96.27%, 94.32%, 92.28% and 86.28% on its own game page, and BigWinBoard agrees. The 9.99-point gap between the top and the bottom costs about €25 more an hour at €0.50 a spin and 500 spins an hour, for identical play.
A Wicked Grin symbol that lands on the bottom row expands up its reel and turns everything above it into Coins or Multipliers; a Multiplier applies its value, up to x20, to the Coins above it and to Coins on neighbouring reels in the rows above. A Super Wicked Grin also makes Wicked Grins on adjacent reels expand. Diamond Coins can be worth up to 500× the bet.
The bonus is set by FS symbols on the bottom row, which expand and add up the numbers beside them for 5 to 30 free spins. Stash N Stack puts a stash above each reel that multiplies Coin values on it; Coin Craze, reached through Super FS symbols, keeps every Coin value in Coin Collectors until the round ends. Hacksaw rates it 3 of 5 for volatility with a 10,000× maximum, released on 8 October 2026.

2 sources, one story.
The studio's own page is read first. Third-party databases are research sources: we name them, and do not link to them. A studio can supply a game in more than one return configuration, and the casino chooses one. A higher figure at one source and a lower one at another usually means they read different configurations, not that one is wrong.

What people ask about this game.
The sources we read list 96.27%, 94.32%, 92.28%, 86.28%. Each is a configuration of the same game; the casino chooses which one runs.
10,000× the stake.
Medium. Higher volatility means longer dry runs between wins and bigger swings in a session.
Because a studio can ship several configurations and each casino chooses one. A review that quotes a single figure is quoting one configuration.
