I made this free 1v1 football card game. Build a deck of hand-illustrated football stars and all-time Legends, set Referee traps like VAR and Red Card, and pick Stadiums that change the pitch. A duel takes about 5 minutes against the AI rival or a friend online.
Summon players onto the pitch, attack your rival's players or go straight for goal, and use Skills and Referee cards at the right moment. The first duel has a short guided tutorial. Works with mouse or touch.
Football Duel was submitted to SlowDen by Helmi Klai. SlowDen did not make this game - it is published here from the developer's own submission, added on 2026-11-09. It runs in the browser with no download, no install and no sign-up.
