Backgammon Variants
French Backgammon
Despite the name, French Backgammon bears little resemblance to Trictrac.
Setup:
Each player starts with fifteen checkers off the board. The players enter their checkers in the opponent's home board, then bring them around the board as shown in the diagram below.
Object:
The object of the game is to move all of your checkers around the board to your own home table and then bear them off. The first player to bear off all of his checkers wins the game.
Start:
Each player rolls one die. The player rolling higher goes first. He may use either the two numbers just thrown or he may roll again. After that, the players alternate turns.
Entering checkers:
You enter a checker by placing it on a point in the opponent's home board corresponding to a number rolled. For example, if you roll 63, then you enter one checker on the opponent's sixpoint and one checker on his threepoint.
You must enter all of your checkers into the opponent's home board before you can begin moving forward.
Movement:
The roll of the dice indicates how many points, or pips, the player is to move his checkers. The following rules apply:
 A checker may be moved only to an open point, one that is not occupied by two or more opposing checkers.
 The numbers on the two dice constitute separate moves. For example, if you roll 5 and 3, you may move one checker five spaces to an open point and another checker three spaces to an open point, or you may move the one checker a total of eight spaces to an open point, but only if the intermediate point (either three or five spaces from the starting point) is also open.
 You must use both numbers of a roll if possible. If you can play one number but not both, you must play the higher one.
Doubles:
Rolling doubles is especially valuable. This is what happens:
 First you play each number twice. For example, a roll of 66 means you have four sixes to use.
 Then you play the complement of the roll. The "complement" of a number is its difference from 7. (Opposite faces of a die total 7.) For example, if you rolled 22 and played four 2's, you also play four 5's (2 + 5 = 7).
 Then you roll again, and if you get another double you play it as described above and get to roll yet again.
If you are unable to use any part of a roll, you lose the rest. For example, if you roll 44 and can only play three of your 4's. Then you are not allowed to play any of the 3's on the other side of the dice, and you do not get to roll again.
Hitting:
A checker sitting alone on a point is called a blot. If an opposing checker lands on a blot, the blot is hit and placed on the bar.
Entering from the bar:
Any time you have one or more checkers on the bar, your first obligation is to reenter those checker(s) into the opponent's home board. You reenter a checker by moving it to an open point corresponding to one of the numbers on the rolled dice. If you are able to enter some but not all of your checkers on the bar, you must enter as many as you can then give up the remainder of your turn.
Bearing Off:
Once you have moved all fifteen of your checkers into your home board, you may begin bearing off. You bear off a checker by rolling a number that corresponds to the point on which it resides, then removing the checker from the board.
If there is no checker on the point indicated by the roll, you must make a legal move using a checker on a highernumbered point. If there are no checkers on highernumbered points, you must remove a checker from the highest point that has a checker.
Strategy:
There are two basic strategies:
 Running game: Run a few checkers around the table in an effort to block points in your own home board and keep the rest of your checkers back to hits the opponent's checkers as they arrive. If you are able to hit a few opponent's checkers, the blocked points in your home board may prevent him from reentering easily.
 Blocking game: You can keep all your checkers together and form them into a prime, which you then roll forward. The only time you will have to break formation is when you encounter points blocked by the opponent.
Differences from Backgammon 
 Play starts with all checkers off the board.
 The winner of the opening roll has the option of rerolling for his first turn.
 If you roll doubles, you also get to play the complement of the roll and then roll again.
