One condition to remember
The Bicycle version requires your partnership to have a canasta before going out, including one completed as you go out.
Practise the explanation
During an open-hand exercise, ask the learner to locate the relevant paragraph in the chosen rules. Let them explain how it applies before moving any cards. The purpose is to practise finding an answer, rather than rewarding a quick guess.
Check the rest in the reference
Read the source’s sections on permission, concealed hands and an exhausted stock. They are separate situations. Our brief note does not attempt to settle them all, and a scorebook entry cannot confirm that an ending was legal.
