An Oxfordshire company specialising in games on the Internet has launched an online version of new TV show The Vault.

Hi2, based in the Harwell Innovation Centre, has set up the site to mirror the format of the ITV1 show hosted by Davina McCall, although the online jackpot is £1,000 compared to £100,000.

Contestants attempt to progress through three quick-fire question rounds online. If they do this successfully, they can open a vault and win the cash.
