MiBs Challenges is a German riddle site started in 2005 with over 150 challenges in 9 categories including math, cryptography, science and many more. Thus, we have a huge variety of different challenges which also range in the level of difficulty. Even though the site is in German we have an increasing number of challenges in English available.
a third site rewriting is currently going on which was really necessary due to PHP and MySQL upgrades. I cannot make any promises about a new release date yet. However, since today the WeChall update script is working again even though you cannot solve any challenges ;)
I liked the design and the challenges there! The site has probably gone forever?
I would like to host the site again if it would be possible to get a backup. If MiB ever reads this he can contact me via mail.

Windows can be secure... but only if you don't use it
