Yuvraj asked people to share their best moments of life with him using the 'Life Ka Balla' (#LifeKaBalla) contest and offered goodies to the winners.
"Share your life's best moments with me using #LifeKaBalla and be the lucky ones to win some goodies," twitted Yuvraj.
The Indian middle-order batsman is one of the most followed celebrities on twitter with almost 1.6 million fans and responses have been pouring after he launched the contest earlier today.
It became an instant hit across all sections of people and among all age groups.
Responses included winning the best student award, climbing the Himalayas to buying the dream house to getting married and having a child.
Yuvraj has recently returned to international cricket after successfully fighting against a rare germ cell cancer.
