Processing and privacy: The result is calculated inside your browser and your data is not sent to any server.
How to use it
- Enter game, numbers already called and draw number.
- The result appears straight away and updates as you edit.
- Copy the result, or copy a link that keeps the same values to share it.
How it is calculated
Balls left = total (75 or 90) - balls called, and each remaining ball has a 1 / left chance. In 75-ball games the letter is added: B 1 to 15, I to 30, N to 45, G to 60, O to 75.
Example
Inputs: Game = 75 ball, Draw number = 1. Result: Next ball: I-30; Called before: 0; Left after this call: 74.
Limits and caveats
- The tool does not remember calls between draws, so paste the updated list each time.
- Repeated numbers in the list count once.
Questions about this tool
How do I run a whole game?
After each call, copy the updated list into the called numbers box, then change the draw number for the next ball.
What is the difference between 75 and 90 ball?
75-ball is common in North America with a 5 × 5 card, and 90-ball is common in the UK with a card of 3 rows and 9 columns.
Can a called number come out again?
No. Every number in the list is excluded and the draw uses only the rest.
