The following was taken from Nautilus article "How Designers Engineer Luck Into Video Games" by Simon Parkin which can be found here.
"Olaf Haraldsson, an 11th-century Norwegian king, once wagered a kingdom in a faith-testing game of dice. Olaf was locked in a territorial dispute with the king of Sweden over the island of Hising; eventually the two agreed to settle the matter with a dice throw. The Swedish king rolled two sixes, the highest possible score, and said there was no point in continuing the game. Olaf insisted on taking his throw; a recent convert to Christianity, he was certain that God would steer the dice in his favour. His faith was vindicated with double sixes. The men continued to take turns throwing their dice, twelve after twelve. The matter was finally settled when, during Olaf’s final throw, one of the dice split in two, to show both a six and a one, winning him the kingdom on an unprecedentedly lucky 13."
