Let the destination guide the choice
If friends have invited you, ask for their complete rules first. If you are learning for an app, find its exact mode and settings. Learning a well-documented version is useful, but it does not guarantee a match with an unlabelled table.
Start from our route page
The beginner route links to the three formats covered here. Each overview names its source so you can move from a short orientation to a complete reference.
Avoid a false shortcut
Do not combine the most familiar parts of several pages into a supposed standard. Keep questions about differences in a separate note until the group agrees which version applies.
