4. Fallas

References, information

 

Fallas is the fourth table game described in the Libro de los juegos (the book of games) written at the request of Alfonso X of Castile between 1251 and 1283. Its name, rendered in French as Failles, here means hindrance, or blockage, and comes from the fact that if a player is unable to play all the dice, he immediately loses the game.


 

1. Equipment

A board with 24 points, 15 dark checkers and 15 light checkers, 3 dice (the players use the same dice), 2 dice cups (one per player).

A backgammon set is suitable, using three dice instead of two. The doubling cube is not used.



2. Starting position

Each player places his 15 checkers as shown in the figure below:



3. Path of the checkers

The checkers follow the path shown in the illustration



4. Object of the game

To prevent the opponent from being able to play all the points shown by the three dice or, failing that, to bring his 15 checkers into the quadrant where his 13 checkers were placed at the start, and then be the first to bear them off the board.



5. Priority for the dice

To determine which player will roll the dice for the first move of the game, each player rolls one die, and the one who scores the most points rolls the three dice to start the game.



6. Validity of the dice

If, on a roll of the dice, at least one of them lands outside the board or ends up on one of the rails, the roll must be completely redone.

If a die ends up tilted and the players cannot agree on the value shown, the roll must be completely redone. If one of the players maintains that the die is good, he may carry out a test consisting of placing another die on top of the die being tested: if the test die slides off, the dice must be re-rolled; otherwise the roll is deemed valid. This test may only be carried out by the player claiming the die is good, and not by the one disputing it.

Dice that land flat on top of checkers are valid.

This is not specified in the Libro de los juegos, but is a rule in particular in Trictrac or Jacquet.



7. Moving the checkers

The checkers are moved according to the result of the dice roll. It is thus possible to move one, two, or three checkers.

Doubles or triples are played as simple moves, each die being taken independently of the others.

It is forbidden to place one of your checkers on a point occupied by more than one opposing checker.

If a checker lands on a point occupied by a single opposing checker, it hits it and takes its place. The checker thus hit must re-enter at the start of the path before another checker already on the board can be played.



8. Obligation to play all the dice

If a player cannot play all three dice, he has lost the game.



9. Bearing off the checkers

Once all 15 checkers have entered the last quadrant, the checkers are borne off the board following these rules:
- in this phase, the outer rail of the board is treated as an additional point
- any checker that can be brought there is borne off, unless, if possible, the player prefers to play another checker on the board instead
- if no checker can be brought to the rail, and no move can be made in the board, one of the checkers is borne off from the farthest point whose number is lower than the value of the die.
