Derby Duel is a live 1v1 football quiz. Not a guessing game: a real opponent is sitting on the other side, the questions arrive for both of you at the same moment, and the winner climbs a leaderboard that never resets.

HOW A MATCH WORKS
Tap play. Matchmaking pairs you with another player in seconds. The same clock, the same questions, both players at once - you watch your rival's score move on your own screen.

PICK YOUR GAME
Pick one from the game pad or play a random one; both players always play the same board: Common Ground, Hidden Star, Over Under, Pair Hunt, Career Twin, XOX, Hit The Target, How Many, Bingo, Shared Badge, Snap, Blurred, True or False, Odd One Out, Whack-a-Star, 3 2 1. Some boards want reflexes, some want squad knowledge, some want a cool head. You can choose which ones show up.

A CAREER, NOT A HIGH SCORE
Your ELO is never reset - it is the measure of your career. Three leaderboards at once: the world, your country and today. A tournament is always open and the next bracket starts in minutes, so this is a ladder to climb, not a one-off quiz. Add a friend with their six-digit code, call them to a friendly and ask for a rematch. While you play, others can watch from the stands.

PLAY FIRST, SIGN UP LATER
You can start playing straight away as a guest. No form, no questions. To keep your career on any device, saving your account asks for a username and a password. An e-mail address is optional and only matters if you forget it. Sign in with Google is there too. We never ask for a phone number.

FAIR PLAY
Gems are the in-game currency and are sold as in-app purchases. They buy cosmetics, coin and tournament tickets. All three can also be earned by playing. They never buy rank, ELO, matchmaking, difficulty or answers - a paying player does not get easier questions.

ADS NEVER INTERRUPT A MATCH
There are no ads inside a match. A slim ad strip sits at the top of some screens and the result screen can show one ad. When you go back to the home screen, a full-screen ad may appear every other match. Rewarded ads open only when you tap "watch" to double a reward. Ads are non-personalised.

IMAGES ARE OFF BY DEFAULT
Player, club and league pictures do not load until you turn them on in Community. Until then the game draws its own avatars and name plates. The choice is yours: a light install or real photographs.

WHAT TO KNOW
Derby Duel is played online - every match is a live server session, so it needs a connection. A match takes a minute or two, which makes it a good queue-time game.

WHO PLAYS IT
Anyone who wins the argument on matchday, knows the squads by heart and follows the transfer window day by day. If you like football trivia, here is an opponent who is always awake; if you have been tapping through guess-the-player games wishing someone real were on the other side, this is that game. Football quiz and soccer trivia, multiplayer sports quiz, guess the footballer, squad and transfer questions, live football knowledge duels - all in one app and one match.
