It's been a wonderful tournament at the Alexandra Palace - and it certainly got the final it deserved.
Luke Littler's fairytale run ended at the final hurdle but the 16-year-old's exploits have brought a plethora of new fans - and perhaps future players - to the sport.
There were will be many days ahead for the teenager but Luke Humphries' story is just as inspirational.
From a man once so plagued by anxiety that he could barely play on the big stage to becoming PDC world champion and world number one.
Thanks for joining us these past few darting days - we hope you've enjoyed our coverage and, come on, get that dusty dartboard out the shed and start throwing a few arrows, eh? Never know where you could end up.

Littler 4-7 Humphries

Luke Humphries has been so resilient and survived so many tough positions in this tournament.
He has proved his merit on every level, throwing and talent but also mental composure and attitude in general.
Post update
Littler 4-7 Humphries
Luke Humphries has also lifted the Ballon D'Art tonight - the trophy for most 180s in the tournament.
It's poignant for him as his father-in-law has recently been diagnosed with prostate cancer - and tournament sponsors Paddy Power have been donating £1,000 to Prostate Cancer UK for every 180 hit at the Alexandra Palace.
There's been more than 900 so the bookmakers will be handing over not much shy of a million pounds.
'I just want to go and win it'
Littler 4-7 Humphries
Luke Littler on Sky Sports: "It's been unbelievable. The one negative was I lost too many legs on my throw so Luke could break me.
"Fair play to Luke, he deserves it.
On moving into the top 32 after his stellar week:
"I would rather be in the top 32 than play the development tour. I am happy, top 32 and runner-up on my debut, it's unbelievable.
"I got to the final and might not get to another for the next five or 10 years. I can say I'm runner-up but I just want to go and win it."
