Wikidata Roundtable is a community game for improving Wikidata. You are shown real problems — incorrect subclass relations, class-ordering errors, broken hierarchies — as interactive graphs, and asked to pick the wrong edge and suggest a fix.

Fixes become real once players independently agree: when at least five players have confirmed a fix for an item and at least 80% of them picked exactly the same set of edges, an administrator can apply it to Wikidata — an administrator's own confirmed pick counts at once. Skips and “Ask Expert” answers are not votes; items without agreement simply stay open for more players.

Along the way you earn XP and level up, collect refs to spend on themes and pinboard decorations in the store, and unlock achievements for reviewing, discussing, and exploring different games.
