Start with the format
Record the player count, partner system and complete reference. If an app offers several modes, write the actual mode label rather than only the application name.
Compare one category at a time
Use separate rows for the deal, picking, no-pick situation, special card obligations and settlement. Put the home agreement in one column and the provider’s explanation in another. Leave an answer unknown when the source does not explain it.
Preserve deliberate changes
A house agreement should be written clearly and shared with all players. Do not silently turn an exception from one account into the default of another. Our learning tools make a small subset visible and do not implement every table option.
