Dudecim Scripta Gamerules

1. To start, both player roll both dice and the highest score goes first. Always throw both dice together throughout the game.

2. Begin with all the pieces off the board. Pieces can only enter at the middle row. You must throw the dice to enter your pieces.

3. Once a piece is entered it can move onto the racetrack and start.
All entry points count the same, so a throw of 3 puts any entered piece onto the third racetrack point.

4. Each time you throw you can chose whether to:
a) enter a piece on any entry point,
b) move an entry piece onto the racetrack,
c) move forward a piece already on the racetrack,
d) move a piece up the entry row, if you don’t want to move a piece on the racetrack.

5. A single piece is knocked off if the opponent lands on the same point and must re-enter the game when possible.

6. You can double two or more of your own pieces on the same point and move them as a pile together as though one.

7. A pile of two or more can knock off an opponent’s pile of the same amount or smaller but not an opponent’s pile that has more than yours.

8. Exact throws are needed to bear off pieces of piles.

9. You must always move if you can.

If you already know how to play backgammon then this game will come naturally.

About moving an entire pile of pieces

If you want to move a single piece of a pile, you just drag and drop it at the destination, as the score on the dice allows.
If you want to move the entire pile, you need to keep the Control button pressed while dragging the pile to the destination.

Note that since you are moving more than one piece, the score of the dice must be a multitude of the number of pieces that are being moved.

Example, a total score of 6 allows a pile of 6 to move one place(6:6=1)
A total score of 6 allows to move a pile of 2 to move 3 places(6:2=3)

Alternatively you can use the score of one Die to move a single piece, or a pile of pieces, and keep the other Die available for moving other pieces on the board.
