Backgammon: play free online, opening moves and strategy

What is Backgammon?

Full backgammon against Brainrot: hitting, the bar, doubles played four times, bearing off, gammons and backgammons. One game at a time, with no doubling cube.

Backgammon is a race with a fight in the middle. Each player has 15 checkers, two dice and one goal: bring every checker home and bear them all off first. Along the way you can hit lone checkers, build walls of points and trap your opponent behind them.

It belongs to a family of dice race games thousands of years old, from the Royal Game of Ur in ancient Mesopotamia to the Roman game Tabula, and the name backgammon appears in English in the 17th century. It's played all around the Mediterranean and the Middle East, as Tavla in Turkey, Tavli in Greece and Shesh Besh in Israel. The doubling cube, which lets players raise the stakes mid-game, was added in New York in the 1920s.

On SkillXGames you play white against Brainrot, with full rules except the cube. Both pip counts are shown on the table, the points you can reach light up when you pick a checker, and you can undo steps until you end your turn. A reload doesn't lose your game: you can resume it where you left it.

How to play

Roll and move

Move one checker by each die, or one checker by both. Doubles are played four times. You must use both dice if you can, or the larger one.

Hit blots

Land on a lone purple checker to send it to the bar. Your own checker on the bar must come back in before anything else moves.

Build points

Two checkers make a point nobody can land on. A row of points traps Brainrot's back checkers.

Bear off

Once all 15 are in your home board (points 1–6), take them off. First out wins 1, a gammon 2, a backgammon 3.

Scoring

A win is worth 1 point, a gammon 2 and a backgammon 3. There's no doubling cube.

Your score is 100 per point won plus the pips Brainrot still had to go. A loss scores 0.

Strategy and tips

Learn the opening rolls

Some first rolls have a clear best play. 3-1: 8/5 6/5 makes your 5-point. 4-2: 8/4 6/4 makes your 4-point. 6-1: 13/7 8/7 makes your bar point. 6-5: run a back checker, 24/13.

Count the pips

Your pip count is the total distance your checkers must travel to bear off. Both sides start at 167. In a pure race, a lead of around 10% is a strong edge.

Know your shot odds

A blot six points from an enemy checker is hit by 17 of the 36 rolls, nearly half. Blots 7 or more points away need a combination and are hit far less often.

Build a prime

Six points in a row is a full prime: checkers behind it can't pass. Even four or five in a row make escape very hard.

Slot when it's cheap

Placing a lone checker on a key point, to cover it next turn, is a risk. Do it when few enemy checkers can reach it or their home board is weak, so a hit costs little.

Bear off safely

If contact remains during the bear-off, clear points from the back first and avoid leaving a checker alone.

Press for the gammon

If Brainrot has checkers on the bar or stuck in your home board, keep attacking: a gammon scores 200 here and a backgammon 300, instead of 100.

Why play Backgammon?

Backgammon teaches you to think in probabilities. Every move weighs safety against progress, and counting the rolls that hit or miss turns a gut feeling into a decision. Pip counting adds a steady habit of quick mental arithmetic.

It's also the clearest lesson there is about luck and skill. The dice decide any single game, but good decisions win far more often over many games, so you learn to judge a move by its quality, not its result.
