The higher volatility manufacturers may send some coins flying or have some special music at 10x, but it’s subdued compared to the bigger win music saved for the 25x and up wins.

On more volatile games, since bigger multiples happen with higher frequency because of the increased frequency of dead spins between them, celebrating 25x makes more sense. Why would manufacturers give different definitions? On lower volatility games, since the pays come more frequently, but are smaller, a 10x win is a bit unusual for those games more often than not, so that’s the threshold where they want to get you excited. But IGT has even broken out the big win graphics (although without the word Big Win) on some games below 10x, like Scarab. Konami has been using their Big Win music and graphics on 10x mini wins on some machines more recently on their more volatile games IGT will sometimes bump up the big win music to a higher multiple. Of course, this isn’t a hard and fast rule.

This includes IGT, IT, Everi, and the Bally division of Scientific Games.

Manufacturers that have had a history of less volatile slots overall tend to use 10x.

This includes Aristocrat, Ainsworth, the WMS and Shuffle Master games from Scientific Games, and many Konami games.

Manufacturers that tend to produce slots with more volatility tend to use 25x as when they break out bigger pomp and circumstance.

Slot manufacturers tend to fall into two camps, and it’s usually based on the type of games they produce. If you were to ask King Jason Slots or Diana Evoni, two prominent slot channels, they tend to dub a 100x win or above a Big Win Bonus. Unlike a handpay, most definitions of a Big Win are based on a multiple, and not a fixed dollar amount. Recently I delved into the definition of a handpay, and whether it needs to change with the times.
