+The 2019 game, *Caldera*, challenged robots to control scoring zones with tokens
+while navigating an arena with raised platforms. Twenty-five scoring zones were
+arranged in a grid, varying in value from two points for each of the outermost
+16, a ring of eight on a raised "volcano" worth seven points apiece, to the the
+central "caldera" which was worth thirty points.
+
+Robots could claim one of the scoring zones by placing more of their tokens in it
+than any opposing robot. Additionally the value of any scoring zone could be
+multiplied by careful position of the robot at the end of the match.
+
+Full details of the 2019 game are available in the [rulebook]({{ site.baseurl }}/resources/2019/rulebook.pdf).
