Time is running out to play the new Chargy Bargy Grand Slam game to try and win some great prizes.
In the new Six Nations version of the game you can choose your nation from any of the six taking part in the championship.
Then you Charge and Barge for glory and for prizes.
Every week of the tournament, O2 are giving away Nintendo Wiis, Blu-ray DVD players and LCD TVs to one of the toughest O2 customers who tops the leaderboard.
What’s more, four lucky winners picked at random from all O2 customers who’ve entered the competition, will snatch VIP tickets to the Emirates Airline London Sevens at Twickenham for themselves and three friends.
