Clicking the "Start Virtual Lab" button on this page or the "Start" button on the start page will launch the virtual lab itself and give it focus. Once it has focus, you can interact using a few common keyboard commands. If you leave the virtual lab's focus, you may need to reload the page to continue playing.
At any time in the virtual lab, you may press "H" for help, or you may press "S" to summarize the current state of the virtual lab and the choice that is in front of you.
