I recently taught my 12 yr old son, who has Asperger's Syndrome (high functioning autism) how to play Black Ice. He LOVES IT! He seems to think it is 'being sneaky' to hide the little piece under the lock.
But, just thought I'd suggest teaching this game to your kids/students that have issues like ADHD or Autism Disorders if you haven't yet. It seemed to be a great game for my Aspie Kids.
