to see who has completed the challenge and which books they read.
Click on the “Submit Entry” button when you finish reading a book that completes the challenge. There will be an “✖️” on the challenges you have not completed and a “✅” on the challenges you have completed. You may read one book per task, or do some multi-tasking by counting one book for multiple tasks.
You get a BINGO if you complete a horizontal, vertical, or diagonal line, and you get a blackout if you complete all 25 squares!
