Ad-supported mobile games firm Cellufun has signed another distribution deal, with US mobile content firm Playphone.

The deal involves Playphone distributing Cellufun's games to its users, but also signing up to advertise within Cellufun's own community.

Cellufun hopes the deal will boost its userbase beyond its current figure of 5.5 million unique users a month, following its deal with AOL Mobile in April.

Playphone will be distributing Cellufun's games on its website, and through a customised WAP site run by the latter company.

As a result of the deal, Cellufun is claiming to be the world's largest "mobile gaming portal providing free entertainment content and casual, connected and multiplayer games for existing and next-generation Web-enabled mobile phones".
