Two games can stay open without mixing their calls.
Create a separate tracker
Name it All Night and load the special cards that will remain active throughout the session.
Use the special pattern
Select the required All Night pattern without changing the pattern used for regular games.
Enter only final calls
After each qualifying bingo game, add its final called ball to the All Night tracker.
See the closest card
The All Night cards rank independently and show which numbers could complete the pattern.
Why use a separate tracker?
A regular game may use dozens of called balls before a winner is declared. The All Night card normally needs only the final number from each qualifying game. Keeping separate call lists prevents the regular calls from being counted on the All Night cards.
Can other special cards be tracked too?
Yes. Create and name additional game trackers for any card group that needs its own paper, pattern, or called-ball history. You can switch between trackers without closing the others.
Does the tracker continue saving?
Yes. Current games save automatically on the device. Paid accounts can sync the tracker with activated devices so it is available after signing in elsewhere.
