+
+	\generic{Playing the game:}
+	% Official size is 7 spaces per side, but variations work.
+	You will need a pencil, an eraser, and a printed hexagonal board. \par
+	Draw your pieces lightly---you may need to erase them. \par
+	Turns alternate. Each player draws distinct pieces (for example, circles and squares).
+
+	\vspace{2mm}
+
+	An example board is drawn below. \say{Spaces} are the corners of the triangular cells, \textit{not} the cells themselves.
+	Points on the edge of the board are also spaces.
+
+	\board{0.4}
+
+	During the first turn of the game, the first player must place one piece onto any empty space.
+	From then on, each player may place either one or two pieces onto empty spaces, respecting the restrictions below.
+	Players may not skip their turn unless they have no legal move.
+
+
+	\generic{Claimed regions:}
+	A \textit{claimed region} is an area of empty spaces that is only adjacent to pieces of a single color. \par
+	No regions are considered \say{claimed} until both players have had a turn.
+
+
+	\generic{Dead groups:}
+	A group of pieces is considered \textit{dead} if it is cut off from all other same-colored groups and is not
+	adjacent to a claimed region. At the end of each turn (except each player's first), erase all
+	dead pieces that belong to the inactive player.
+
+	\generic{Restrictions:}
+	\begin{itemize}[itemsep=1mm]
+		\item A piece may not be placed inside a claimed region.
+		\item A piece may not be placed adjacent to two (or more) same-colored pieces if those pieces are also
+		neighbors of each other. In other words, you may not form small triangles of one color.
+
+		\item When placing two pieces adjacent to each other in a tun, they may not form a
+		straight line with a third pre-existing piece of their color.
+	\end{itemize}
+
+
+	\generic{Ending the game:}
+	The game ends when both players run out of legal moves.
+	Each player's score is calculated by counting the number of empty spaces in regions they have claimed. \par
+	The player with the highest score wins.

+	\begin{ORMCbox}{Notes}{ogrape!10!white}{ogrape}
+		\begin{itemize}
+			\item
+			Each player needs to make multiple groups before the first player's second turn. \par
+			Otherwise, all their pieces will be removed from the game, resulting in an early loss. \par
+			Do not make your first moves next to each other!
+
+			\item Groups are easiest to secure near the corners or along the edges. Play there first. \par
