Frequently Asked Questions
When and where does the Handball World Championship 2027 take place?
The IHF Men's Handball World Championship runs from January 13 to 31, 2027 in Germany – matches are played in Munich, Stuttgart, Kiel, Magdeburg, Hanover, and Cologne. The final round takes place at Cologne's Lanxess Arena.
How much does it cost?
Pricing depends on package and participant count. Request a free quote – we'll get back to you within 24 hours.
How long does setup take?
You're typically live within 48 hours. With the full-service package, we handle all branding and setup for you. With self-service, you configure the game yourself.
Is it GDPR compliant?
Yes. Riddle is ISO 27001 certified. All data is stored on German servers, with backup in Luxembourg. A DPA (data processing agreement) is available on request.
Can I use my own domain?
A custom domain is part of the Enterprise package. With Growth and Enterprise, you can also embed the game as an iFrame on your website. Alternatively, you get a subdomain like brand.tippspiel.fans or brand.predictions.fans – your choice.
Does my team need to manage the game?
Barely. Results and leaderboards update fully automatically. Winners are drawn automatically – you just notify them and send out the prizes.
Handball World Championship only, or other events too?
A Convert campaign covers one tournament or season at a time – from the FIFA World Cup to the Champions League and the EHF EURO. Ready-made campaigns are also available for the Bundesliga season 26/27 and EURO 2028.
Why Convert instead of a free prediction-game tool?
Free tools are built for private groups, not brands. Convert is 100% white-label (your branding, your domain), with GDPR-compliant hosting in Germany, ISO 27001 certification, automatic scoring and winner drawing, lead export as CSV or Excel, and hands-on support – a sales-ready campaign, not a DIY toy.
Can we build the game ourselves – and does AI help?
Yes. In self-service you build your campaign yourself – and the AI generator does the heavy lifting: one prompt and it creates questions, answer options, explanations, and matching images that you curate in minutes. Prefer to hand it off? Choose full-service and we set everything up.
How can sponsors be integrated?
In many places: branded bonus questions, logo placements on the home, results, and leaderboard screens, and sponsored prizes. Many publishers and clubs fully refinance their campaign through a single prize sponsor.
Does the prediction game run in English or other languages?
Yes, in any language. Whether it's an international workforce or a multilingual audience: the prediction game runs in German, English, French – and any other language you need.
What if we expect more participants than the package covers?
No problem – extra participants can be added flexibly. For larger volumes you move to the Enterprise package. Just tell us the reach you expect.
