O'Sullivan has signed up with UK online casino King Solomon's, which, for the first time in snooker, will see branding permitted on the arms - the most visible part of the player during televised games.
Previously branding has been restricted to waistcoat breast pockets and lapels.
The sponsorship package will include O'Sullivan playing poker live online, allowing consumers to play against him.
The package also secures King Solomon's strong brand exposure at the Benson & Hedges Masters currently being held at Wembley.
The sponsorship package was arranged by Dynamo Marketing as part of an ongoing campaign for King Solomon's.
