Secure Your Drupal Forms with CAPTCHA Riddler the Easy Way
A smooth form experience can keep visitors engaged, but a tough CAPTCHA often drives them away. CAPTCHA Riddler offers a simple fix with easy, human-friendly questions that stop bots without slowing people down. This guide explains what it does and how to set it up on your Drupal site.
CAPTCHA Riddler for Drupal and Backdrop CMS
CAPTCHA Riddler gives websites a simple way to keep bots away while keeping forms easy for real users, especially on setups where issues like Drupal Ajax errors on file upload can make form handling feel less stable. It works through human-friendly questions that act as a quick check before a form is submitted. People answer a short riddle or question and move on fast, while bots fail.
Site owners like this approach because it feels natural and personal. It also matches the look and tone of the website, which creates a smoother form experience for visitors.
How CAPTCHA Riddler Works
Administrators set up their own questions with clear answers. When someone tries to submit a form, the system picks one question at random. The user answers it and continues. The process stays light and easy for humans while still stopping automated spam.
The module accepts more than one correct answer for each question. This gives site owners flexibility when writing their riddles. It also helps users avoid mistakes when wording their replies.

Text-based questions often feel more friendly for people with vision challenges, especially when compared to traditional image puzzles. This makes the form experience more open to everyone.
Install and Configure CAPTCHA Riddler in Drupal
CAPTCHA Riddler adds custom questions to your forms and helps your site avoid spam. It works as an add-on to the main CAPTCHA module. Before you start, make sure your Drupal site is ready, and you have full admin access.
What You Need Before You Begin
- A working Drupal setup that supports the module
- Access to the server command line for Composer or the option to upload modules manually

Step 2: Update CAPTCHA Settings
- Go to the admin config, people, captcha.
- Pick Riddler as the default challenge. Add a short message if you want users to know why they see the question. Adjust settings like case sensitivity and answer rules. Save your setup.
Step 3: Add Your Questions
Look for the Riddler section on the same page. Create your questions and add the answers. Simple and clear questions work best for real users and still stop bots.
Step 4:Apply Riddler to Your Forms
- Open the CAPTCHA points page. You will see forms like registration, login, and contact forms.
- Choose the forms you want to protect and edit each one. Set Riddler as the challenge. If a form is missing from the list, add its form ID and assign Riddler, which is also helpful when you need to add a hook form alter in Drupal 8 to manage custom or missing form IDs. Save your changes.
Step 5: Test Your Setup
Open a protected form in an incognito window. Admin users skip CAPTCHA, so this step needs a guest view. Make sure your question shows up and accepts the correct answer.
