Stated teaching profile
Examples and the classifier use one 52-card deck, no Jokers and three distinct physical cards. The sequence convention places A-K-Q above A-2-3; other profiles may differ.
Original exercises
Practice questions are educational examples. They do not represent a real game record, predict a future deal or compare players.
Sources and product claims
A rule reference may use a different profile. No app is described as tested without an observation record. No verified installer was supplied, so download information does not invent a destination.
Corrections
Include the page, statement and rule profile when suggesting a change through contact. Never send account secrets. No official publisher affiliation is claimed.
