How snooker works, in one minute
A frame starts with 15 reds (1 point each) and six colours on their spots: yellow 2, green 3, brown 4, blue 5, pink 6 and black 7. You alternate: pot a red, then nominate and pot a colour, then a red again. Potted colours return to their spots while reds remain.
When the last red is gone the colours are taken in order — yellow, green, brown, blue, pink, black — and stay down. The highest total wins; the most a player can make in one visit, with every red followed by the black, is 147.
A foul gives your opponent the value of the ball involved, at least 4 points. After a bot's foul you choose: play on from where the white stopped, or make the bot play again.
