i couldn’t find how the “trap card” was determined

• falsedan 8y ago
  On the "how it works"[0] page, they explain that they choose a card in the first row and perform the walk. The point of the trick is, it's extremely likely that, regardless of the initial card chosen, the walks will merge (and thus step onto the trap card you chose when setting up). 0: http://faculty.uml.edu/rmontenegro/research/kruskal_count/index.html http://faculty.uml.edu/rmontenegro/research/kruskal_count/in...

  It's explained here albeit vaguely: http://faculty.uml.edu/rmontenegro/research/kruskal_count/index.html http://faculty.uml.edu/rmontenegro/research/kruskal_count/in... You start at the first card and progress until you would fall off the end on the next step. That card you're on is what you pick as the trap.
