Backgammon Tournament Rules
A backgammon tournament uses the same board rules as a casual game, plus rules about format, time and conduct. Here's what those tournament rules usually cover, and exactly how they work in online tournaments on NARDEON.

The board rules don't change
A tournament game is ordinary backgammon: same setup, same moves, hitting, bearing off, gammons and backgammons. What tournament rules add is everything around the board — how players are paired, how long a match lasts, what happens with the dice and the clock, and what counts as a forfeit.
Format: knockout brackets and seeding
The classic backgammon tournament format is a knockout: players are drawn into a bracket, the winner of each match goes through, the loser is out. Brackets come in powers of two — 8, 16, 32, 64 — and if fewer players register, the leftover slots become byes. Many events seed the bracket, placing the strongest players so they can't meet in the first round. Large live events sometimes add a consolation or "last chance" bracket for early losers; NARDEON's tournaments are a single knockout.
Match length and scoring
Tournament matches are played to a set number of points, nearly always odd. Each game scores 1 point for a single win, 2 for a gammon and 3 for a backgammon, and the first player to reach the target wins the match. Most club and federation events play with a doubling cube, which brings in extra rules such as the Crawford rule; NARDEON plays without the cube, so a match is simply a race to the target score.
Dice and the clock
At a live tournament the rules usually ask that:
- dice are thrown from a cup and must land flat on the board to your right — otherwise you roll both again;
- you don't roll before your opponent has finished their move;
- a move is finished once you pick up your dice (or press the clock), and can't be changed after that;
- stronger events use a chess-style clock with a time bank, so nobody can stall.
Online, these problems disappear. The server rolls the dice and the dice can be verified after the match. You can undo steps until you confirm your move, and the clock is strict: 12 free seconds per move, then a 2-minute time bank for the match, and never more than 60 seconds on a single move. Run out of time and you lose the match. If you lose connection, you have a minute to return.
Show up on time
Every tournament punishes no-shows. At a club, the director waits a set time and then awards the match. On NARDEON, when both players in a pairing are free, the game calls you to the board. You have 3 minutes to press "I'm ready". Miss it and it's a technical loss; if neither player shows up, the higher seed goes through.
Etiquette
- Greet your opponent and say "good game" at the end — online there are quick reactions for exactly that.
- Play at a steady pace; don't run the clock down to annoy someone.
- Don't comment on your opponent's luck. Everyone gets bad rolls.
- At a live event, keep your dice in the cup until it's your turn, and leave disputes to the director.

FAQ
What format do backgammon tournaments use?
Most use a knockout (single-elimination) bracket: win your match and you go through, lose and you're out. Bigger events sometimes add a consolation bracket for first-round losers. NARDEON tournaments are single knockout.
How long are tournament matches?
Usually an odd number of points, so a match can't end in a tie. Club events often use 5, 7 or 9 points, with longer matches in later rounds. On NARDEON the tournament sets the match length: 1, 3, 5 or 7 points.
What happens if my opponent doesn't show up?
At a club the director gives the match to the player who arrived after a set waiting time. On NARDEON, each player has 3 minutes to press "I'm ready"; miss it and you lose by default. If neither turns up, the higher seed goes through.
What is a bye in a backgammon tournament?
A bye means you go to the next round without playing. When the number of players isn't a power of two (4, 8, 16, 32), the top seeds get byes.
Is there a doubling cube in NARDEON tournaments?
No. Games are worth 1 point, a gammon 2 and a backgammon 3, and the first to the match length wins.
