A bet book for long-running family wagers

'I bet you the Cubs win it before you finish that renovation.' Half the fun of a long bet is remembering it exists. The bet book keeps the terms, the parties, and the date it comes due.

Predictions lock when they are made; later changes are recorded separately. Attach a receipt, mark a bet ready to judge, settle the winner, and watch the scoreboard.

• Multi-party bets with wager terms: bragging rights, money, chores, meals, or custom prizes.
• Review dates with due-soon and overdue views.
• Original predictions lock; amendments are logged separately.
• Attach notes, links, screenshots, or photos as receipts.
• Settle winners, void unresolved bets, and keep outcome notes.
• Scoreboard of correct, incorrect, open, and voided per participant.

Families and friend groups who bet in chores and bragging rights.
