Set up the agreement

  • State whether the prompt means planets in the Solar System, fictional planets, exoplanets, or another named category.
  • Choose one reference before submissions and record any allowed alternative spellings or names.
  • Select note as the default proof unless spoken continuity is part of the actual challenge.
  • Hide other submissions until the participant's answer is locked so earlier names cannot become hints.

Evaluation rubric

  • The submission contains five distinct names inside the agreed planet category.
  • Every name matches the preselected reference or an explicitly accepted alternative.
  • The answer arrives through one allowed format before the visible deadline without hints.

Edge cases to decide before starting

  • A name is misspelled but unmistakable: apply the spelling rule written before the round.
  • The note contains six names with one wrong answer: use the exact-five or first-five condition chosen in advance.
  • Another participant posted an answer early: keep later attempts hidden or restart the affected round rather than pretending no hint existed.

Privacy checks

  • Create a fresh answer note instead of sharing a screenshot containing notifications or account history.
  • A video alternative needs only the spoken attempt, not a room-wide frame or identifiable background.
  • Keep wrong answers and recordings within the agreed group to prevent unwanted ridicule.

Ways to adapt this template

  • Name five moons, constellations, capital cities, musical instruments, or items in another fixed category.
  • Use three names for a quicker round or seven for a new harder invitation.
  • Ask each participant to predict the most common correct set before the private reveal.

Safety and privacy standard

Apply the standard to “I can name five planets in a row.”: participation stays voluntary, and people may pause, stop, or choose a safer and more accessible alternative without penalty. Never turn the activity into danger, humiliation, discrimination, sexual pressure, medical direction, illegal conduct, or financial coercion.

Collect only the least revealing proof needed for this page’s agreed rule. Remove unrelated people, messages, locations, notifications, and account details; private submission never authorizes wider sharing. Read Proovem’s complete editorial, safety, privacy, sourcing, and correction standards.
