The sponsorship specialist teamed up with Global Games earlier this week to produce a bespoke fan event at The Trafford Centre.
Fans were asked by promotional staff from agency Kreate to declare their allegiance to either City or United and show their support by scoring a goal for their team.
City fans took the early lead but Reds supporters ended up on top with an accumulative score of City 41 United 66.
Former player at both clubs Denis Law was on hand to greet fans and take part in the game.
In addition, Betfair has been offering rival fans in Manchester an opportunity to create a chant to be immortalised on a giant billboard in the city centre.
The winners were United fan Rohan David who wrote ‘MUFC - making history not buying it', and City fan Sam Steel who hit back with ‘The past was yours but the future's ours'.
The twin poster will be overhauled again following the game on Saturday to reveal the winning team's colours and give one of those fans the final word in the derby.
