Spin for a number from 1 to 15
Fifteen even slices, each with about a 6.7% chance. Fifteen is just right for small classes, small raffles, and one column of a bingo card.
Bingo B numbers
In 75-ball bingo, each letter has its own block of fifteen numbers: B is 1 to 15, I is 16 to 30, N is 31 to 45, G is 46 to 60 and O is 61 to 75. This page is set up for the B column. To call the other columns, change From and To in the fields, like 16 to 30 for I.
Tip: For a full game of bingo on one wheel, set the range to 1 to 75 and use Remove from wheel. Work out the letter from the number: 1 to 15 is B, 16 to 30 is I, and so on.
Small classes and groups
- Who answers next: number your students and spin. Remove each name as they answer so everyone gets a turn.
- Raffle of fifteen: number your tickets and spin for the winner.
- Fifteen-minute slots: a workshop day split into fifteen slots? Spin to assign them.
- Practice problems: spin for which of fifteen questions on the sheet to go over together.
Fair draws
The wheel uses your browser’s cryptographic random number generator to pick the result before it spins. Every number on the wheel has the same chance, and removing a number only changes what’s left. For a bigger class, try 1 to 25 or 1 to 30.
