Billiards (8-ball pool) is a 2-player game where each player pots their group of balls (solids or stripes) and wins by finally potting the black 8-ball. It demands precision, cue control, and positional thinking. Play free billiards online at BoardGame Battles.
📖 Rules — How to Play, Step by Step
- Billiards here means 8-ball: 15 numbered balls — 7 solids, 7 stripes and the black 8 — plus the cue ball.
- After the break, each player's group (solids or stripes) is set by the first ball legally potted.
- You keep shooting as long as you pot a ball from your group. Miss, and the turn passes.
- A shot is legal if the cue ball strikes a ball from your group first. Hitting the wrong ball is a foul.
- Potting the cue ball is also a foul and gives your opponent ball in hand — they may place it anywhere.
- Only after every ball in your group is potted may you go for the 8-ball.
- Potting the 8-ball early, or alongside a foul, loses the game instantly.
💡 3 Tips to Win
- Always plan the cue ball's position after the shot — not just the ball you're potting
- Pot your opponent's blocking balls when you have a clear angle
- Play safety shots when no clear pot exists — position matters more than attacking
♟️ Advanced Strategy
A beginner thinks about the ball he wants to pot; a good player thinks about where the cue ball will stop. Potting is the easy part — what decides the game is finishing the shot with an open angle on the next one. A potted ball that leaves the cue ball frozen on the rail is, in practice, the end of your turn.
Before you start clearing the table, read the whole layout and pick an order. There is nearly always a problem ball — stuck on the rail, blocked by an opponent's ball, or sitting too close to the wrong pocket. Deal with it early, while you still have your own balls scattered around to play position from.
An opponent's ball blocking your pocket is a problem that only gets worse. If you have the angle, move it out of the way early, even at the cost of a shot.
When there's no good shot, don't force one. A safety — leaving the cue ball tucked behind one of your balls, with no angle for your opponent — is worth more than a desperate attempt that opens the whole table for them.
The three-point rule: before every shot, decide three things — which ball you're striking, which pocket it's going into, and where the cue ball will stop. If you can't answer the third, the shot isn't ready. It's that simple, and it's what separates someone who pots a ball from someone who clears a table.
Side spin is the last thing you should learn, not the first. It changes the cue ball's angle off the object ball and is irresistible to beginners, but it introduces error into nearly every shot. Master power and a still cue ball first; spin only pays once you're already consistent without it.
⚠️ Common Beginner Mistakes
- Aiming only at the object ball and ignoring where the cue ball ends up.
- Attempting hero shots the table doesn't allow, and handing over position for free.
- Leaving the problem ball for last, when nothing is left to help you play position.
🕰️ History and Origin
Billiards began as a lawn game, something like croquet, played by European nobility in the 15th century. It was moved indoors onto a table covered in green cloth to mimic grass — which is where the green baize survives from. Rails were added to stop balls falling off, and only afterwards did someone realise bouncing off them was fun.
Snooker itself was invented by British officers in India in 1875. But the most played cue game in the world — and the one here — is 8-ball, an American invention of the early 20th century, with 15 balls split into solids and stripes and the black as the final target.
🔀 Game Variants

Only nine balls, potted in numerical order. Fast and highly tactical.
Snooker
A larger table, 21 balls and a colour-based points system. The British professional game.
Straight pool
Any ball, any pocket, called in advance. The classic American tournament format.
🌐 How It Works Online
Billiards at BoardGame Battles is 8-ball, with shot physics, spin and power control. You aim, set the strength and strike — the rules on fouls, ball in hand and instant loss on the black apply exactly as they do on a real table.
Play people through matchmaking or take on the AI. On hard, the AI plays safeties: when it has no clean pot, it hides the cue ball rather than attempting the impossible — which is precisely what a good player does, and precisely what annoys anyone used to bots that always attack.

How are solids and stripes determined in 8-ball?
The first player to legally pocket a ball after the break gets that group. If you pocket a solid, you play solids (1–7); if you pocket a stripe, you play stripes (9–15). If you pocket both on one shot, you choose.
What is a foul in 8-ball pool?
Fouls include: pocketing the cue ball (scratch), failing to hit your own balls first, and not driving any ball to a rail or into a pocket. After a foul, your opponent gets ball-in-hand (places the cue ball anywhere).
When can you pocket the 8-ball?
Only after legally pocketing all your group's balls (all solids or all stripes). Pocketing the 8-ball early — or pocketing it with the cue ball — results in an immediate loss.
What is a break shot in billiards?
The break is the opening shot where you hit the rack of 15 balls with the cue ball. A good break scatters balls widely and often pockets one or more, establishing your group.
