Lottery fixers charged with fraud in US

A former lottery computer administrator and a friend have been charged with racketeering and theft by fraud for allegedly rigging a 2007 lottery game which netted them more than $US780,000 ($A1.1 million) in the US.

The pair were charged on Thursday in Wisconsin by the state's attorney-general's office.

It's alleged Eddie Tipton, from Texas, modified computer data so he could pick a winning number for the December 29, 2007 Megabucks draw.

At the time Tipton's job was to write software to randomly select numbers for lottery computers in 37 US states.

His friend Robert Rhodes, also from Texas, confessed to the scheme and said Tipton recruited him to help win jackpots by getting him to use a series of numbers to play, one of which won the jackpot that Rhodes collected and later split with Tipton.
