Useful Instructions for playing DSI

  1. Make up a unique USERNAME for yourself... something unique you can remember. You need it to come back and continue saved cases. Leave "Class code" set to "demo3".
  2. Play all five cases. Start with "Zoe Goes Swimming" if you want a tutorial. Other cases are harder, with less help!
