Unsurprisingly, I'm not a big Club Penguin fan, but the Disney-owned online community RPG for 6-14 year olds is massively popular with over 150 million users.

Puffle Launch, its mobile companion game for iOS and Android - it's a physics trajectory game - is also popular with an active fanbase of around 150,000 players daily across mobile and web.

That's a number Disney is looking to increase dramatically with the release of a Lite version for iOS and Android, which provides six of the paid game's 36 levels for free,

What's more significant, however, is the stickiness of its cross platform interaction as you use the same account across web and mobile.

In the two months since Puffle Launch was released, over 100 million virtual coins earned in the mobile game have been transfered into the main Club Penguin world.
