- The page reports testing with more than 5,000 cards; the optional phone feed depends on a future shared server funded by donations.
Field notes
The workflow covers setup as well as the live draw: organizers can define prize order and win conditions, enter cards, and handle tie-breaks. During play, the page describes voice announcements, an undo for the last number, and a “Ça chauffe !” indicator for cards one number away from a win. It also lists a post-event log, printable summary, exports, and a full-draw simulation for practice or estimating event length.
