Tabula - Professor Finkel's Rules
(Mostly)

(Rules as taken from https://a4games.company)

1. The game is played on a board of twenty-four points by two players,
each having fifteen pieces of a distinguishing colour.

2. The moves of the pieces are controlled by the alternate throws of three six-sided dice. If, for example, the numbers 1, 3, 5, were thrown:

(a) Three pieces could be moved, one 1 point, one 3 points, and one 5
points, as long as each resting point was not blocked by enemy pieces;

or

(b) two pieces could move, e.g. one piece by 1 point, and the other piece by 3 plus 5, or 5 plus 3, or any other combination desired;

or

(c) one piece could move 9 points if each resting place were free, i.e. 1 plus 3 plus 5, or any reorientation of these numbers, e.g. 5 plus 1 plus 3.


3. The pieces are entered on the board in the first quarter and travel
anti-clockwise round the track. Both colours travel in the same direction. It improves the game if no piece is allowed to enter the second half of the board until all the player's pieces are entered into the first half. (This rule is not enforced by this rendition of the game.)

4. If a player has two or more men on a point, this point is closed to
the enemy and the pieces on it cannot be captured. These are called
Piled Men or Ordinarii.

5. If a player moves a piece on to a point occupied by an enemy singleton, the latter is sent off the board and must re-enter the game at the next possible throw. No other piece can be moved until it is reentered. Singletons are known as Vagi.

6. Pieces unable to move because they are blocked by enemy Ordinarii are known as Inciti. A player must use the whole of his throw if this
is possible even if, as happened to the unfortunate Emperor Zeno, it is
to the player's disadvantage: any part of a throw, however, which is
unplayable is lost and the turn passes to the opponent.

Note: You can load the Emperor's position in this game in order to see the predicament he was in. (Menu option:File:Setup Emperor Zeno's conumdrum)

7. An additional rule not mentioned by classical writers which improves the game is that no piece may be borne off the board until all the player's pieces have entered the last quarter. If a player starts bearing off and a vagus is hit, no further pieces can be borne off until it has re-entered the final quarter again.(This rule applies to this rendition of the game).

8. An exact throw is needed to bear off a piece. (Rule taken from the predecessor of this Game: Duodecim Scripta)

If a player is allowed to bear off pieces, the image of a bear will appear under the players bear-off bin.
