 By choosing heads or tails when Jason and Kevin flip to see who will ride in   the front, you cannot change what happens, only change what side of the coin   Jason calls for (He calls Heads in the theatrical version). Regardless of   the choice, Jason always wins, But if you select tails, after the   premonition Wendy snatches the coin while its in midair and freaks out, not   even getting on the coaster. Jason, Carrie and Kevin follow her out, then   the coaster crashes. Some text comes up explaining what ultimately became of   all of them (none die) and then the movies ends.
