To celebrate our sponsorship of English test cricket, we've introduced the npower test cricket game.

As any decent batsman will tell you- you need concentration, timing and excellent shot selection to play a big innings. And you've got 12 overs and 10 wickets to build an unassailable total. At the end of the game, enter your score to see if you rate as one of the all time greats!

When you've tired of decimating our bowling attack, why not calculate how much money you could be saving on your gas, electricity, telephone or insurance!
