Guess the voting numbers must be down, so they'll try and get money this way

UK broadcaster Channel 5 has teamed up with online and app developer JadeWorld to launch a playalong game for its rebooted reality series Big Brother.

Big Brother's Matchphrase lets viewers win prizes by answering questions about Big Brother in real time. Games include naming which housemate has said a particular phrase, will cost £0.69 to enter and offer minimum cash prizes of £1,000.

The game was developed in association with Big Brother creator Endemol. JadeWorld has previously created a service called Whoozaround, which is a real-time location app.
