Make a challenge worth sharing

Create a custom recall challenge, check answer aliases, preview it and share a link. Import or export JSON, with drafts saved in this browser.

Drafts stay in this browser. Shared links contain questions and answers.

One to ten questions. One accepted answer per line: answer | aliases separated by commas | points (10, 20 or 30). Your first example can be viola | | 20. Use your own material; avoid private information.

Import a challenge JSON

Write a fair question

Specify the category and any boundary in the question itself. “Name a planet in our Solar System” is clearer than “Name something in space”. Add alternative spellings that should match, then check that the same alias has not been given to two different answers.

The prototype validates structure and duplicate aliases, not factual truth. Its 10/20/30 values are your exercise weights. They are not official Krillion scores or measured percentages of other players.

What sharing does

Preview validates the current draft and opens the local practice player. A share link contains a compact copy of your questions and answers in its fragment; recipients need no account. The answer key can be inspected by a recipient. No live room, public publishing feed or cloud draft storage is created.

Keep the complete JSON export as a backup. Imported text is checked before replacing the draft; an invalid import leaves your current work intact. Long challenges may exceed the share-link limit and can still be exchanged as JSON files.

Keep the next game close
