The most people in a mobile phone game relay was 2,030 and was achieved by Nokia (Malaysia) in Kuala Lumpur, Malaysia, on 11 June 2011.
The game played during the relay was 'Angry Birds'. The game was played continuously, with each individual participant clearing or failing one level of the game, for a total of 10 hours. The reason that Nokia Malaysia decided to stage the record attempt was to strengthen the association between the highly popular game 'Angry Birds' and Nokia's new smart phones. On the day of the record attempt Nokia created an 'Angry Birds Playground' with themed activities for the public to engage in throughout the day. People of all ages (the youngest being 2 years old) participated in the record attempt.
