You Need to Sign Up!
The reason we require you to be a member is to prevent cheating and hacking. We track every player's progress in a database to confirm they have answered every riddle correctly without skipping any.
There are many benefits of registering. The site stores your answers and tracks your progress for you. That way, you can leave and come back and pick up where you left off, instead of starting at the beginning again. Registering also enables you to participate in the forum discussions.
