Secret Sync

Choose a number from one to five without showing it. On a shared count of three, reveal it with fingers, a spoken number, or a card-free signal. Try three rounds to see whether the pair can sync once; change your strategy after each reveal.

Skip at any time without penalty. Stay seated; say or write a number instead of using fingers, and treat a mismatch as useful information rather than a loss.
