Thunderkick

Thunderkick is a Swedish studio: in its own words, it “set out in 2012 as a small studio looking to shake things up” and has grown to a team of more than 80 in Stockholm, with every slot designed and developed in-house. We carry 88 of its games.

The RTP range is the headline

Across the 88 Thunderkick games on this site, the published RTPs run from 94.08% to 98.6% — four and a half points between the worst and the best game from the same house. Some studios spread further (Play’n GO’s range is over eleven points), but four and a half is already more than any welcome bonus is worth.

It means one practical thing: “a Thunderkick slot” tells you nothing about the return. Two games from the same studio, with the same art direction and the same polish, can sit four points apart. Each game’s page shows its own figure; compare there, not here.

And the usual caution applies on top: the figure on our pages is the studio’s published one, and the casino chooses which configuration it installs. The game’s own info panel is the only number that applies to your money.

What the studio says about itself

Thunderkick’s own site is short on specs and long on process: every slot and every feature, it says, is “carefully thought out, developed, and designed within our own studio.” That is a claim about how the games are made, not about how they pay — which is why the numbers on each game page matter more than anything on this one.

How to use this page

• Sort by RTP, not by reputation. With a four-point range, the studio’s name is the least useful filter.
• Open the demo first. Art-led slots are the ones where a free round tells you most — you know within a minute whether the game’s rhythm suits you.
• Check the RTP line in the casino before real money. The page lists the studio’s figure; your casino lists the one it runs.
