About this site
thunderkick-demo.com is an independent guide to Thunderkick slots. Every review puts the studio's own free demo on the page, copies the figures Thunderkick publishes for the game, and adds a demo session we played and logged ourselves, so you can try a game and check its numbers in one place.
What is on a review page?
There are 8 reviews so far. Each one starts with the title and four key figures, then the playable demo, then the article: a short answer to the question people ask most about that game, how the game plays, our session, the feature buy where there is one, the rules in plain words, a comparison with the other Thunderkick games here and a verdict. A fact file sits beside the text with every figure and where it comes from.
- Figures from Thunderkick: RTP, volatility label, grid and ways or lines from the game page; maximum win, bet range and feature buy prices from the demo server.
- Our own play: 6,000 paid demo spins across all reviews, logged one by one, plus screenshots, the rules screens and a recorded free spins round for every game.
How do we test a game?
We open the game in a testing tool that plays the public demo and writes down the stake, the win and the features of every round. Each slot gets 750 paid spins at €1.00, a second session for screenshots and the rules screens, and one free spins round recorded from start to finish, bought where the game sells a feature buy. The tool checks its own sums against the balance the demo server reports after every round.
Seven hundred and fifty spins show what a short session feels like: how often the game pays, how large an ordinary win is, whether the bonus arrived. They cannot confirm an RTP. Thunderkick works its figures out over millions of rounds, so our numbers always sit next to the studio's and never replace them.
A casino can run a different RTP version of the same game than the demo does, and some markets switch the feature buy off. When the RTP matters to you, check the game's information screen at the casino before you play.
Where does each number come from?
Every figure on the site has one source, and the source is the same on every page. Release dates need two listings that agree, because review sites often publish before a game goes live.
| Figure | Source |
|---|---|
| RTP, volatility, reels, ways or lines | The game's page on thunderkick.com, "Game details" |
| Maximum win, bet steps, demo balance | Thunderkick's demo server configuration, read without placing a bet |
| Feature buy price and its RTP | The same configuration, one entry per buy option |
| Rules and features | The rules screens inside the game, transcribed from our screenshots |
| Catalogue totals on the home page | Every game page linked from thunderkick.com/games/, read on the date shown there |
| Session figures, charts, clips | Our own demo play, logged by the testing tool |
How does the site make money?
The demo window on each review shows a partner casino that accepts players from your country, so the casino and the welcome bonus you see depend on where you are. Its links are affiliate links: Play for real money and Get the bonus in the side column, the gift in the corner of the game, and a panel that slides in after a minute of demo play and again every two minutes. If you sign up and play, the casino may pay us a commission. You pay nothing extra.
No casino can buy a better review. The facts and the text stay the same whichever casino appears beside them, the panel closes with one click, and the demo never needs an account. Bonus terms belong to the casino and can change, so read them there before accepting a bonus.
Are we connected to Thunderkick?
No. This site is not run, endorsed or checked by Thunderkick. Game names and artwork belong to the studio and appear only to identify the games under review; every picture of a game here is our own screenshot of the free demo. The demo window loads Thunderkick's public play-money client from forfun.thunderkick.com, the same one the studio uses for its own demos.
Mistakes are fixed as soon as they are confirmed, and each page shows the date of its last change. To report one, write to hello@thunderkick-demo.com.
Playing safely
Real-money gambling is for adults only, 18 or older and 21 in some places, and it can become a problem for anyone. The demos run on play money and are a safe way to see how a game behaves; at a casino, set a budget before the first spin and stop when it is spent.
- BeGambleAware: advice and the National Gambling Helpline for Great Britain.
- GamCare: free support, including live chat.
- Gambling Therapy: free help worldwide, in many languages.
- Stödlinjen: the Swedish helpline for gambling problems.
- GAMSTOP: free self-exclusion from UK-licensed gambling sites.
What do we collect?
There is no advertising and no third-party analytics. A small first-party script counts visits: it keeps a random visitor ID in your browser's local storage and sets two session cookies, a session ID and the page you arrived from, which expire after 30 minutes. They hold no name, e-mail or payment details and are not shared. The server keeps standard access logs for security.
When you press Play, the game loads from Thunderkick's servers, and the studio's own privacy policy covers that part. Partner links pass through our redirect at /out/, which records the click (time, country, page and button) so a commission can be matched to a page, and hands a click ID to the casino's affiliate programme. On the casino's site, the casino's privacy policy applies.
