Accessibility at Riddle Technologies AG

This statement applies to Riddle.com interactive content embeds, which are designed to comply with level A and AA criteria of the Web Content Accessibility Guidelines (WCAG) 2.2 – the international standard for accessibility of websites and applications.
Compliance We strive to provide an accessible experience and actively work on improving our interactive content product, and the Riddle.com interactive content embeds meet most of the WCAG 2.2 level A/AA criteria. However, some issues remain to be addressed in order to reach full compliance.
Help and feedback

Contact us via our support chat, by sending an email to hello@riddle.com, or by completing the form below and we'll make sure you get the help you need as soon as possible. We'll reply in the way you prefer.

Note that you have the option to file a complaint with the market surveillance agency of your country in case your issue is not resolved.
How we work with accessibility We fix all known accessibility issues as soon as possible. In the future, tooling and expert guidance will prevent the introduction of new accessibility barriers into the product. We commit to a third-party consultancy reviewing our products and new features before launch to ensure that new functionality is accessible and also works with the existing functionality. We provide ongoing accessibility training for our designers, developers, and project managers. In addition, we also consult users with disabilities in design processes.
Our accessibility partner Since April 2025, we've partnered with Axess Lab, a leading accessibility consultancy. They conducted a thorough review of our application and continue to support us with our accessibility needs.
Known remaining barriers
  • Visually impaired users can encounter images without a descriptive text alternative.
  • Screen reader users can encounter invisible text as well as unlabeled buttons.
  • Unless our default Timeless Palette is selected and not altered, contrasts of some UI elements and texts are insufficient, affecting users with low-vision and color vision deficiency. To ensure readability, select the "Atkinson Hyperledgible" font type (developed by the Braille Institute).
  • Keyboard users are unable to fully interact with drag-and-drop tasks or with block types that require vision. We show a list below of block types that by default cannot be made accessible.
  • For users with cognitive disabilities, automatically advancing to the next question might be disorientating. Riddle offers the ability to auto-advance to the next question, but this option must be enabled. Auto advance only works with single-select question types. Refrain from using any multi-select block types if auto-advance is a key requirement for you.
  • Low-vision users will struggle with zoom in certain circumstances.
  • Some information is only available for users who can see the screen.
