The teenage sensation admitted his quarter-final victory at the World Darts Championship wasn't as seemless as it may have seemed because he had been unable to practice and felt a little rusty at the oche after a few days away from play.
He told Sky Sports: "I am very happy to get through. Obviously I have not been practising for nearly two and a half, three days.
"I tried to change my throw here, there and everywhere. Most importantly, I got the job done.
"Just not practising, just being lazy in the house. Obviously, we've not brought our dartboard down.
"So yeah, I can't really practice, but I would have loved to. Now we play day after day so hopefully tomorrow's a bit better.
"We stayed in the house last year and it worked. Obviously, last year, house, no board, won it.
"House this year, no board- see what happens!"
Luke - who faces Ryan Searle in Friday's (02.01.26) semi-final - was booed on his walkout after previously insisting he isn't bothered about fan criticism, but he's admitted he's keen to have their support at London's Alexandra Palace.
He said: "Obviously, it is a new year, first day of the year. A few boos here and there.
"But as soon as I got on stage, the crowd was absolutely unbelievable. Leading up to it, family and friends were just like, whatever happens, happens.
"As soon as I got on stage, I clapped everyone just so they knew, I want them on my side again. They were on my side tonight and I got the job done. So hopefully, it is the same again tomorrow.
"I am growing as a player mentally. I know how to deal with it and I think the Rob Cross game definitely tested me. But yeah, I got through it. In future games, I know how to deal with it and get past it."
