After losing in the first round of the opening two ranking events of the year, Allen won the minor-ranking Ruhr Open in Mülheim, Germany, by beating Ding Junhui 4–1 in the final.&lt;ref name="2013/14"&gt;&lt;/ref&gt; He also won the next European Tour event, the Kay Suzanne Memorial Cup by battling past former world champions Neil Robertson and Graeme Dott in the quarter-finals and semis respectively. He beat Judd Trump 4–1 in the final to become the first player to win back-to-back events since they were introduced in 2010. In the last 16 of the UK Championship, Allen and Judd Trump both struggled for consistency during their match, with Allen giving Trump a hug when the pair missed a succession of easy balls. Allen went on to win 6–4 to reach his first major quarter-final of the season, where he lost 6–2 to Ricky Walden. Allen came close to recording a hat-trick of World Open titles as he won through to the semi-finals, but was beaten 6–4 by Shaun Murphy. His two titles earlier in the season meant Allen was the number one seed for the PTC Finals where he lost in the quarter-finals 4–2 against Gerard Greene. Allen was 9–7 behind against Neil Robertson after the second session of his last 16 match at the World Championship and lost all four frames in the next session to be defeated 13–7. Afterwards, Allen tipped Robertson for the title saying he had faced perfect snooker from the Australian.
