2026 Soccer Showdown Predictor is a free fan tool for World Cup group stage matches. Pick what matters to you — form, home edge, star players, and more — set weights that add up to 100, score each team, and get an instant win-percentage call plus a shareable poster. Send your link to friends: they can load your setup, tweak their own weights, and see who called it better after the final whistle. Available in English, Spanish, and Chinese. For entertainment only — not betting advice.
