Gory Games is a spin-off quiz show based on the ever-popular Horrible Histories series on CBBC, the British kids TV channel.

A new app for iOS and Android tablets and smartphones now lets children take on the studio contestants, test their knowledge of gruesome facts and win virtual prizes whilst watching the show live, or on-demand with BBC iPlayer. During certain Gory Games episodes a play along logo is displayed to alert children that they can play along. The app, freely available from from Google Play or the Apple App Store, 'listens' out for the TV programme and then synchronises with it, allowing kids to answer questions alongside the studio contestants in order to win 'Year Spheres'.

The app design and user experience was produced by SyncScreen and is powered by the proprietary SyncScreen Framework API. It's the first such app to be produced in-house by SyncScreen's creative team. A play-along app for CBBC series Ludus using the SyncScreen API was designed by Cube Interactive and launched in January 2014. However it involved synchronising more traditional app mini-games to the studio game show.

Both apps make use of Civolution’s SyncNow Automatic Content Recognition (ACR) technology, which uses audio-watermarking to enable real-time identification and thus a synchronised interactive experience for users.

"We wanted to create the optimal play along experience for Gory Games, using all our editorial know-how and design insight to produce a fun, immersive and sympathetic two-screen TV experience for children " said Marc Goodchild, SyncScreen's Creative Director. “Crucially, from a creative and production process perspective, our SyncScreen Framework made the synchronisation functions easy to implement. Civolution's SyncNow watermarking solution was the underlying enabling tech for frame-accurate cue detection, and we used it to maximum effect".
