+# The Scene
+
+Several people agree to convene to play a game of dice. Beforehand,
+they decided on the number of sides a given die should have. Once they
+do that, each player brings with them a die of that many sides (for
+example, 6, 12, etc.; even a coin can count as a die in this case.)
+
+A random number is selected from one of the die faces. Each player is
+tasked with rolling their die until they hit that number.
+
+For example, three players get together and decide to use an ordinary
+six-sided die each.
+
+The player to hit the number in the smallest number of turns,
+wins. There can be more than one winner.
