We know it’s been a while, but we promise you that it’s not going to happen anymore. We’re excited to introduce you new features we have been working on.

Stay Updated

We’ve added a new topic at CTF Master page with the latest challenges, so you can keep track of what’s new.

Recently added challenges

Better ranking pagination and Friends raking tab

Now you have a better way to navigate through ranking instead of only doing next, next and next. Also, we’ve added a friends tab so you can easily see the ranking between you and your friends.


Ranking of your friends

So far we have only two badges. Get rewarded for completing your registration and for solving your first challenge.  New Badges to come.
