Yggdrasil games: observed play

86.6% of observed rounds returned nothing, give or take 0.49 points.

What we measured

What these numbers mean

Every figure on this page is counted from rounds that real players settled on 2 casinos, read from each operator's public bet feed. Nothing here comes from Yggdrasil or from the casinos' marketing, and nothing is estimated from a game's advertised return to player.

Across 18,290 rounds of 61 Yggdrasil games, 86.6% paid back nothing at all. The rest returned something, from a fraction of the stake up to the largest win we saw, 279 times the bet. A high share of empty rounds is normal for high volatility slots, which pay rarely and big; it is not by itself a sign that a game is unfair.

Questions

Are Yggdrasil games fair?

Niekie does not certify fairness; that is the job of the testing labs a studio contracts. What we can show is how Yggdrasil games actually behaved: 18,290 rounds counted from casinos' public bet feeds, of which 86.6% returned nothing.

What is the RTP of Yggdrasil slots?

We do not publish a studio-wide RTP for Yggdrasil or any other studio. Pooling games with very different payout scales makes the average swing far more than the sample can support, so any single number would be misleading. We publish the share of rounds that return nothing instead, because that figure settles quickly and is true.

Where does this Yggdrasil data come from?

From settled rounds on 2 casinos that publish live bet feeds, collected continuously between 2026-07-30 and 2026-11-01. House games, distribution platforms and feeds that provably show only winning rounds are excluded.

We publish no return to player figure for Yggdrasil, or for any studio. The reason is arithmetic, not caution. Individual games, where the sample allows, are on the games page.
