Jonny Clayton, Jermaine Wattimena, Chris Dobey and Kim Huybrechts were the first players to book their places in Phase Three of PDC Home Tour II on Tuesday.
The quartet qualified from Phase Two Group one as they continued their bid to claim victory in the tournament in October.
Clayton, Wattimena and Dobey all won five of their six matches on the day, while Huybrechts won three games to claim his Phase Three place.
Clayton, Sunday's runner-up in the German Darts Championship, was in particularly impressive form as he averaged 110 and 106 amongst four ton-plus averages on the day.
Alan Tabern finished in fifth place with two wins, and will now have to wait to find out if he progresses as the best fifth-placed player following the five groups in Phase Two.
Stephen Bunting and Daniel Larsson are eliminated from the tournament following Group One, with the St Helens ace winning just one match and the Swedish thrower ending without a victory on Tuesday.
Wednesday's Group Two will be headlined by Poland's Krzysztof Ratajski, German duo Gabriel Clemens and Martin Schindler and Hong Kong's Kai Fan Leung, as well as Mickey Mansell, Ted Evetts and World Youth Championship finalist Bradley Brooks.
The PDC Home Tour II will be broadcast through PDCTV and bookmakers' websites worldwide, with play commencing from 0930 UK time on each day.
