+
+	\section{Rules}
+
+	Your team will have 45 minutes to work on 20 estimation problems.
+	The answer to each problem is a positive real number. Your team will
+	submit intervals for each problem, which (ideally) contain the specified quantity.
+
+
+	\vspace{2mm}
+
+	An interval is \say{good} if it contains the true value. After the end of the game,
+	your team's score will be calculated as follows:
+
+	$$
+		\Biggl(10 +\sum_\text{good intervals}\biggl\lfloor\frac{\text{min}}{\text{max}}\biggr\rfloor\Biggr)
+		\times 2^{20 ~-~ \text{number of good intervals}}
+	$$
+
+	For every problem you miss or leave blank, your score doubles. \par
+	Your job is to \textbf{minimize} your score.
+
+
+	\vspace{8mm}
+
+	Every team will get 25 answer sheets. You may use one of these sheets to submit an interval at any time.
+	Make sure you write your team name, problem number, and interval (min and max) every time you submit.
+
+	\vspace{2mm}
+
+	There are 20 problems, but you are given 25 answer sheets. You may re-submit your solution to any problem
+	(as long as you have sheets remaining). Your latest answer will be kept.
+
+	\vspace{2mm}
+
+	Your interval may not use any mathematical operations except for scientific notation \par
+	(for example, $[2 \times 10^2, 3 \times 10^2]$ or $[2\text{e}2, 3\text{e}2]$)
