Intercontinental Hotels Group (IHG) ran a global competition to offer a free nights stay at any of their hotels in the winner's desired location. 

​

We were briefed to create a competition mechanic that allowed entrants to select where in the world they would like to go by selecting the location using a pin on a map. We then linked to IHG's hotel look up API to display the closest IHG hotels to the placed pin. Entrant's could then enter their registration details to give themselves a chance of winning. 

​

The client requested to this to work over desktop, tablet and mobile, however we had to overcome the issue that there would be no internet access at some of IHG's key events where they were promoting the campaign (and had iPad kiosks at their events), so we had to build an app that allowed registration information to be stored on the iPad's local storage. 

​

We then developed a batch process for the iPad that when run, would download all entry information to the main database, to ensure all entries were correctly logged.
