There was a recent Staff vote for removal of Logic missions as the answers may be found on Google and are distributed elsewhere. Many users believe that the Logic missions do not "teach", although they find the Logics enjoyable. Many OTHER users believe the Logic missions only provide "extra points" and are irrelevant to hacking. We apologize for the inconvenience.
HTS Staff are reviewing the Logic missions, so they are disabled at the moment. I will keep users updated. Otherwise, if you have any feedback, complaints, or suggestions, please voice here and/or blame me.

Signed,
Monica
