Unlike traditional polls, ranki uses the Elo rating system—the same algorithm used to rank chess players worldwide. When you vote, you're presented with two items from the Best onsen in Barcelona list. Your choice doesn't just add a "point"; it adjusts the relative scores of both items based on the strength of their opponent.
This creates a highly accurate, dynamic leaderboard that reflects the collective wisdom of the community. With 155 votes cast so far, these rankings are the most definitive way to see what truly comes out on top.
