Quick start
Choose one game from the collection, read its opening rules and inspect the starting board. Try one deliberate move and observe the response before continuing.

Game Conveni 21 — About this game
Begin with one game and look at what can be selected before committing a move. Compare the first result with the objective, then build a short sequence that makes sense for that board. If you switch activities, start again from its instructions; a useful move in one game is not automatically useful in another.
