What it does
Plysion is a team-based trivia game with a Jeopardy-style twist. Pick 6 categories — each with easy, medium, and hard questions worth 200, 400, or 600 points. Miss it, and the other team can steal your points. One category updates live: World Cup 2026, with fresh questions added as real matches happen, plus a score-prediction feature that rewards exact guesses with a free game. First game free. Built solo with AI.
