Volatility describes how a slot’s wins are spread out. A low-volatility game pays small amounts often. A high-volatility game pays less often, but its wins can be much larger. Some providers call it variance. It’s the same idea.
Volatility and RTP measure different things
RTP is how much a game is set to pay back over millions of spins. Volatility is how that payback arrives. Two slots can both have a 96% RTP. One might pay back through frequent small wins, and the other through long dry spells broken by rare big ones. RTP says nothing about which of the two you’re playing. Volatility does.
A game’s maximum win is a rough clue. A 12,798x cap, like Fu Zhu Bao Bao’s, only makes sense if a lot of the payback is saved for rare large wins, and BetMGM’s page for the game rates it High. But a cap is a limit, not a rating, so we never infer volatility from it.
How providers rate it
There’s no common scale. Each provider uses its own:
- Words. Yggdrasil uses labels from Low (3 Piggies of Bank) through Medium-High to High (Valley of the Gods). Gaming Realms rates its Slingo games Medium Low (Slingo 49’s) or Medium (Slingo The Godfather).
- Numbers. Hacksaw Gaming rates games out of 5. Its four new games in our calendar, Dr Zappo, Great Game Serengeti, Le Vampire and Wicked Grin, are all 3/5.
Providers don’t publish a shared definition, so a “Medium” from one isn’t directly comparable with a 3/5 from another. To filter the calendar, we group the ratings into three bands: 1/5 and 2/5 count as low, 3/5 as medium, and 4/5 and 5/5 as high. Word ratings fall into whichever bands they name, so “Medium-High” counts as both medium and high.
Why most games show “not published”
Most new slots don’t publish a volatility rating on the pages we can check. As of 19 October, 11 of the 43 games in our calendar have one. Play’n GO, for example, published none for its August and September releases on the pages we checked.
We only list a rating the provider or a licensed casino publishes, and each one links to the page we found it on. If there’s none, we write “not published” instead of estimating one from the paytable or copying it from a review site.
What to do with it
Volatility is a description, not a recommendation. If you want a game that keeps a session going on a small budget, low volatility suits that better. If you’re chasing the top prize and accept long losing runs, high volatility is built for that. Either way, the RTP and the outcome of any session are separate questions.
