About Root Me
Challenges range from easy to very hard, so it suits learners and experienced players. After you solve one, you can read the solutions other players wrote. A section called CTF all the day gives you virtual machines to attack.
The core content is free, and you need an account to validate challenges. A non-profit association runs it, and it has been online since 2010. The site is available in several languages, including English.
