Play a challenge together

Blind match

Choose a list and create a blind-match invite. Send the link to your partner. Each of you needs 15 actual votes in that list before the comparison is revealed. Existing votes count; arranging items does not add votes.

You can take turns in your own time. The result shows where your rankings agree and differ. Invitees can sign in or join as a guest.

Duel

Choose Duel and a round count. Both players answer the same pairs, and each round reveals your choices after both have answered. You can play together or return to finish later.

Short lists stop after every distinct pair has appeared, even if you chose more rounds. Choices lock once saved; refreshing or retrying cannot change a revealed answer. A finished duel shows its shared and contrasting choices, and Start a new duel creates a fresh invitation.

Duel choices stay separate from your personal ranking until you choose Add to my rankings after the game. Reopening or importing the same duel again does not duplicate its votes. If your list has changed, the votes are saved into a separate duel copy.

Send an invitation

Open Share in a list, then Play together. Choose Duel or Blind match and create its invite link, even if you have no friends yet. You can also invite an accepted friend directly, or use Challenge beside a friend on the Friends page. Opening an invitation does not silently add a list to your library.

Friends shows pending and in-progress matches. Finished games appear under the Archive link: a duel finishes when both players answer every round, and a blind match when both unlock the reveal.

Use the archive icon to put an unfinished match away just for you. It stays playable for the other person. Archive labels it Unfinished; open its menu and choose Resume to return it to your active list and keep playing. Delete match permanently removes it from your history only; the other player’s copy and your list rankings stay unchanged.
