Before you play
Do I have to finish a pack in one sitting?
No. Packs group a few puzzles together, and each round saves its own progress. Continue pack brings you back to an unfinished puzzle before starting a new one.
How does the movie matching game work?
Choose a puzzle, then drag a poster to a category or tap to place it. Use each movie once and fill every category before checking. Individual matches can overlap, but each board has one complete solution.
Are these the same as the daily movie puzzle?
The library is available whenever you want another round. The daily challenge is shared by everyone and resets at midnight Eastern. Library rounds and archive plays stay separate from your daily streak.
Is Cast Six free to play?
Yes. The daily puzzle, past puzzles and themed library are free. No account or download is needed; progress saves for your current browser.
