Where can I check for solutions to the Blood Donation (Zebra puzzle) from Brainzilla? I tried their website, but they did not have an 'answer section' available yet. I emailed them and they gave me a link to this forum to see if I could get what I needed here. I am a teacher and like to use logic puzzles and the like to help my students with their critical thinking skills.

Thank you :)

    $\begingroup$ I think that Brainzilla might be a little confused about what exactly this site is. It is not a "forum", but rather a question-and-answer site. As such, we host both questions about puzzles (like you have above), and puzzles to be solved. What we don't do is host discussions about puzzles (except in our chat rooms). You could try asking your question there, or, if you have permission from Brainzilla, you could post the puzzle itself here as a question (with proper attribution, of course), and see if anyone can solve it. $\endgroup$ – GentlePurpleRain Sep 20 '18 at 16:16
  • $\begingroup$ Thank you for your quick and kind response. I will try the chatroom and see if by doing that, I get the information I need. $\endgroup$ – Tracy Sep 20 '18 at 16:22
