Keep the player order fixed
Read the names aloud before entering a result. A player’s role may change, but the scorebook column should continue to identify that same person. Renaming a column does not move its earlier entries.
Confirm the final changes
The manual ledger asks for signed game-point changes already agreed by the group. It does not ask for the captured points inside a trick. Read both the numbers and their signs before saving.
Check the sum
The tool shows the sum of a hand’s five changes and flags a non-zero result for review. It does not reject that result or decide a settlement. Use your complete rules and table agreement to resolve an unexpected number.
Export before leaving
The record stays in this browser. Export CSV before Reset, clearing site data or moving devices. Undo removes the latest hand. For an older error, keep a copy before rebuilding the record. Avoid putting private account information in notes.
