He returned to Countdown for Series 72, starting his run with an impressive 14 maxer against Charlene Rose. Seven more victories, including two by more than 100 points to confirm him as the clear number 1 seed for the finals. In his quarter-final, Cappleman failed to score a century for the first time, but returned for his semi-final with an impressive 12 max against Kevin Steede, to set up a final with Tracey Mills. Despite falling behind early on, Cappleman took the lead after the first numbers game and never looked back, eventually winning 107 – 89.
Cappleman returned to the studios in January 2016 as one of sixteen entrants in Championship of Champions XIV. Playing in the first preliminary match of the tournament, he defeated Series 69 semi-finalist Glen Webb. With both players spotting all three of the game's available nine-letter words, this game proved to yield a joint score of 248 - the highest thus far achieved in the "new" 15-round format. In the quarter-final, Cappleman faced Series 68 champion Giles Hutchings but lost on the crucial conundrum ULTIMOLEG.
In July 2016, Cappleman appeared on Series 12 of Only Connect as part of the "Verbivores" team alongside fellow Countdowners and Phyl Styles and Series 65 champion Graeme Cole. They went on to win the series in April 2017.
