Football Duel Card Game: We Lost a 15-Turn Match to Its AI

Football Duel is a free card game that runs in a browser tab, with footballers as the cards. We played one match against its AI on the Pro setting, without an account. It took 15 turns and 7 minutes 13 seconds, and we finished on 0 Fan Support to the AI's 4,400.

The substitution that lost us the match

On turn 8 we brought on Vinícius, a 9-star forward with 3,350 attack. The how-to guide prices substitutions by star rating: 1 to 5 stars come on free, 6 and 7 cost one player sent to the bench, and 8 and up cost two. So Merino and Nwaneri went off. The game asked us to confirm and told us "This can't be undone".

Vinícius attacked Barella, a 7-star midfielder. Our opponent was a deck called Calcio, run by an AI the game names "The Coach", and it had a card set face down. That card was a Red Card, and it sent Vinícius off on his first attack. The confirmation box hadn't mentioned that risk, though the how-to guide does call Referee cards traps.

We now had nobody on the pitch. The guide says an attack on an empty pitch lands at the attacker's full value, and on turn 9 Barella hit for 2,450 and Tomori for 900. Our Fan Support dropped from 7,250 to 3,900 in that one turn.

On turn 11 The Coach played Legend's Call, sent Tomori and Barella to the bench and brought on Gattuso at 3,200 attack. He took out our face-down Lewis-Skelly. Two turns later he beat Brahim by 1,600 and Rabiot hit us directly for 1,750, which left us with almost nothing.

The tutorial is the start of a real match

We clicked the tutorial link on the home page expecting a practice mode. Its 18 guided steps run inside a real match against The Coach instead, and when the last prompt says "Brilliant, you know the basics!" you carry on with the same game. Our 15 turns include those steps. We think that's a good way to teach a card game, because you're already in a match when the prompts stop.

The steps are short. In ours, Trossard (1,700 attack) beat The Coach's Darmian (650), and Darmian's Last Breath gave The Coach 500 Fan Support back. The guide says 3 and 4-star defenders and goalkeepers do that when they're sent off, and our Lewis-Skelly later did the same for us. A Bicycle Kick skill card then added 800 attack to Trossard.

The guide says a first match lasts "5 to 15 minutes". Our session ran from 11:15 to 11:23, tutorial included.

What the full-time screen showed

The full-time screen puts the two sides next to each other. Ours against The Coach's: players sent off 3 and 5, direct hits 1 and 5, damage dealt 5,100 and 9,000, biggest hit 1,850 and 2,450, players brought on 7 and 9. Barella was player of the match. The Coach signed off with "Good game. Train harder and come back."

Under the table there's a line that reads "Create a free account to keep this result and get The Special One", with a Sign in button. We never needed an account to play, which matches the home page's promise that guests can. We didn't check whether a guest's result is saved.

One match can't tell you how hard Pro is (Rookie and Legend are the other two settings) or how balanced the decks are. We saw one Starter XI deck and one Calcio deck. The deck-building guide asks for exactly 40 cards, at least 14 players rated 1 to 5 stars and no more than 3 Legends.

On a phone-sized screen

On desktop Chromium the home page loaded in about 3 seconds. The page has an ad slot, but no ad appeared while we played.

We also started a second match at phone size (390 by 844 in an emulator, so treat this as a rough check). Nothing scrolled sideways. A pop-up asking us to create a free account covered the home screen before we could press Play, and we closed it. After that you choose one of six decks, the opponent's deck and the difficulty, then play rock-paper-scissors for the kick-off. We stopped there. The numbers on the cards in hand are small at that size.

What else the game's pages list

According to the FAQ, you can open a private room and share a 4-letter code to play a friend, with chat and optional voice, or join a random public match. It lists 6 themed starter decks, a deck builder and 278 cards, 168 of them real 2025/26 players, plus Gold Messi and Ronaldo cards assembled through "Golden Fusion". The meta description promises "No download, no sign-up". The studio calls itself "a small independent game studio in Tunisia" and the game "a fan game" that is "not affiliated with any player, club or league".

For licensed football we cover EA FC 27 and Football Manager 27, plus its PC requirements. For more games that run in a tab, see our best new browser games for November, browser games to play with friends, .io games by genre, GeoGuessr alternatives and the browser games hub.
