Frequently Asked Questions

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 – and even at short notice: we've set up campaigns just 3 days before kick-off. With full-service, you provide your logo, colors, graphics, and copy – we build and configure the entire campaign and support you closely with any questions. With self-service, you configure everything yourself.
Is the platform 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. Participant data stays within the EU, is never sold or shared, and is deleted after the campaign 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 your game or calendar 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 it?
Barely. Results and leaderboards update fully automatically. Winners are drawn automatically – you just notify them and send out the prizes.
Which events can I run campaigns for?
We offer prediction games for every major tournament and league – World Cups, European Championships, the Champions League, Olympics, national leagues, and more (licensing per competition). Ready-made campaigns are currently available for the Bundesliga season 26/27, the Handball World Championship 2027, and EURO 2028, plus seasonal formats like the digital advent calendar. Don't see your competition? Get in touch.
What is a company prediction game?
A company prediction game (also known as an office pool or office sweepstake) is a branded prediction game a business runs for employees, customers, or fans – with leaderboards, bonus questions, and prizes. Convert delivers it white-label: GDPR-compliant, live within 48 hours, fully automated, for any major sporting event or league.
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 handling, CRM lead export, 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 and doors, 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.
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 and we’ll share the right tier.

15-minute demo. We'll show you exactly what your game or calendar looks like with your brand on it.
