I am adding a label in my app, and it contains the text "Add puzzle" or "Solve puzzle". I was thinking also about "exercise", "challenge".
This game / puzzle / exercise is an easy game, like tic-tac-toe, you can play with different users, but before it starts, need to set up. I need a title for this setup phase.
Would you use the word "puzzle" in an online game or a different one?
