Channel 7 reality show The Mole to take on The Block Sky High and MasterChef Shura Taft is the host of the revamped reality show The Mole. Channel 7 is out to sabotage The Block Sky High and MasterChef Australia by screening The Mole three nights per week. The revamped reality show, hosted by Shura Taft, premieres on Tuesday July 2 at 7.30pm. The Mole will continue on Wednesday and Thursday at 7.30pm. Previous editions of The Mole only screened one night per week. The move is a huge gamble for Seven which has resurrected The Mole after an eight year hiatus. The Mole has never been a monster ratings success for the network. Running it three nights a week at 7.30pm puts it up against the strongest competition yet. The Block Sky High has been averaging around 1.2 million viewers per night. MasterChef Australia is more vulnerable, regularly averaging between 700,000 and 800,000 viewers per night. "This is the cleverest trick Seven could play," media analyst Steve Allen says. The Mole offers something quite different to the competition (on Nine and Ten). It is a great alternative. The Mole revolves around 12 contestants who face off against each other in a series of challenges. The twist is that one of the contestants - The Mole - is out to sabotage his or her rivals. One by one, each contestant is eliminated from the show based on their ability to identify the Mole in a regular quiz. The last player standing will win a potential $250,000. The contestants include law graduate Seble, lifeguard Jayden, community youth leader Hillal, building sales representative Shaun, design consultant Ally, AFL development officer Sam, and human resources manager Kerrie. Art gallery assistant Nick, sponsorship co-ordinator Erin, communications graduate Aisha, medical secretary Linda, and engineer Alex round out the list.
