Decalogue is based on the events that took place in four books of the Bible: Exodus, Leviticus, Numbers, and Deuteronomy. The object of the game is to collect and keep all Ten Commandments Tablets and cross the River Jordan into the Land of Canaan. Players roll dice and move around a board, taking the actions prescribed by the spaces they land on. The game provides a unique and educational way to interact with other players while learning about the faith, offerings, plagues, and blessings of the Old Testament. (user summary)
