Turner CN Enterprises is joining forces with Winning Moves' Top Trumps brand to launch a special Ben 10 iPhone application.
Ben 10 Top Trumps already exists as a physical games pack and has sold over 600,000 units in the UK.
The iPhone app - which is priced at £1.79 - was developed by Acrossair and includes a pack of 30 character cards enabling users to play either against their phone or a Bluetooth multiplayer version.
In addition to Apple's app store, it can also be found in a dedicated Ben 10 room on iTunes.
"With a stable of strong licence partner brands that Top Trumps could have chosen from to launch their first iPhone app, we're delighted that they chose to collaborate with Ben 10," said Joe Braman, commercial director EMEA, Turner CN Enterprises, DVD, Mobile & Digital. "Sales of the physical pack continue to go through the roof and it's the perfect format for mobile, making this an exciting next step in our existing partnership."
