The Royal Game of Ur, also called The Twenty Squares, is an ancient strategy race board game originating in Mesopotamia during the early third millennium BC. The goal of each player is to advance their pieces along their path by rolling the dice.
You can choose which stone you want to move, as long as the move is legal. But be careful! In the middle section, stones can send each other home by landing on the same square.
Landing on a roll-again square grants you an extra turn. But you cannot move to an already occupied roll-again square.
In order to land on an end-square you need to roll the exact number of squares to advance to it.
Bring all of your stones to the end to win.
