Ready to Bingo is a free online bingo number caller that runs entirely in a web browser. Its primary function is to draw random numbers for 75-ball and 90-ball bingo games. The tool uses the Fisher-Yates shuffling algorithm combined with the browser’s secure random number generator (crypto.getRandomValues) to ensure each draw is random and that no number is called twice. All processing occurs locally on the user’s device; no data is sent to a server. Once the page is loaded, the drawing, voice, and timer functions work without an internet connection. The caller offers several features to support different game formats and settings. Users can draw numbers by clicking the displayed ball or pressing the space bar, and the backspace key undoes the last draw. An auto-draw mode calls a ball every ten seconds. A number checker allows users to tap any number on the board to verify whether it has been called. Projector mode hides menus and advertisements, displaying only the ball and board for use on large screens. The voice caller supports English, Spanish, Portuguese, German, and French, using the voices installed on the device. The page also requests the browser to keep the screen awake while the tool is open. Game progress is saved in the browser, so closing and reopening the tab resumes the previous game; a new game option resets the session. Typical use cases include family game nights, classrooms, care homes, clubs, and fundraisers. The tool also includes a bingo card generator that produces printable 75-ball cards and 90-ball tickets. Users can switch between 75-ball and 90-ball modes without losing progress in either game. The 75-ball mode follows the American format with letters B, I, N, G, O corresponding to number ranges, while the 90-ball mode uses numbers 1 to 90 without letters. The website provides additional resources such as bingo guides, printable cards for occasions like Halloween, baby showers, and Christmas, and information on how to play virtual bingo. The tool is supported by optional donations to keep it free.
