World Invite official rules
Here are the key differences between World Invite Rules and all other habits.
Classic Lag for Break. Closest to the rail wins the lag.
World Invite rules strictly prohibit the use of an opponents ball to pocket your shot. In 8 ball all shots must be called if not obvious. Player must call the shot exactly how it is to play out. Any deviation is a foul. Rail first does not need to be called.
9 Ball flukes are legal. There is no shot clock on the last shot of the match up.
It's still open after the break. It remains open until a player legally pots a ball and thus becomes that set.
Any foul results in Ball in Hand. A player can place the cue ball anywhere on the table to start their turn. Ball in Hand allows the player to shoot in any direction, anywhere on the table.
A player scratches when they fail to make contact with the called object ball or the cue ball falls into a pocket.

The ELO ranking system is a smart way to measure a player's true skill by adjusting their score based on who they compete against. If you beat a stronger opponent, your score goes up more; if you lose to a weaker one, it drops more. It’s not just about winning—it’s about who you beat. Our proprietary ELO system goes further by factoring in game-specific elements like match format, equipment difficulty, and even performance trends, giving players a more accurate and dynamic ranking across multiple sports.
Our app is built to handle large-scale competitive ecosystems with precision and reliability. It supports up to 1 million active users simultaneously, with scalable cloud infrastructure to accommodate league organizers, casual players, and global events across 16 different sports. Whether tracking a neighborhood pool match or a worldwide chess tournament, the app can score, rank, and archive every match in real time. Each game result is stored with up to two decimal places of score precision, ensuring highly accurate results for games where every point or frame matters—especially in formats like Straight Pool, Carom, Archery, and Golf scoring.
The proprietary ELO algorithm driving the app uses a dynamic computation engine tailored to each sport’s unique structure. It adjusts player ratings instantly after each match based on opponent strength, equipment difficulty, and scoring margins, delivering highly responsive and fair rankings. The app’s performance index (IPL) also aggregates player skill across multiple sports with real-time updates and cross-discipline compatibility. League scoring, tournament bracket logic, and ranking updates all operate with millisecond-level response times, allowing the app to run large tournaments and asynchronous leagues without delay or data bottlenecks.
