Some even predicted John could be the next Chaser.
"This guy John is amazing. £11,000 on his cash builder," one said.
Another added: "Could John be a new Chaser?"
"11 out of 11. What a machine, John, well played."
A fifth said: "How long until they bring John in as the seventh chaser?"
The Chase has been on air for 12 years and it has become one of ITV's most loved shows.
Walsh, who has been hosting the popular game show since 2009, recently revealed that if he beat pro quizzers Anne Hegerty, Shaun Wallace, Jenny Ryan, Paul Sinha, Darragh Ennis and Labbett, he would air it for the world to see.
"If I beat the Chaser, we'll make a series, let's do that," he said.
"Oh I'll definitely beat them, if I can beat them, we'll make the series, alright?"
