DSD saw more than 1,000 agents take part in stage one of the programme, and stage two has modules on the DSD team, city break activities, inspirational tours and SeaWorld Parks & Entertainment.
An interactive card game challenges agents to match pictures before progressing on to questions on each of the topics.
A leaderboard pits agents against one another. Prizes available include a Mulberry purse, a Fitbit, an iPad and a radio-controlled inflatable Minion.
Annabel Cove, head of trade sales and marketing, said: “DSD Doubles has had such fantastic feedback from agents and we’re excited to reveal this next stage in the programme.
“A wildcard draw – which is new for this year – encourages agents to keep going, regardless of their position on the leaderboard, meaning more prizes for everyone taking part.
“We’ve kept the emphasis on fun and added some healthy competition to ultimately expand their booking potential by adding on some of our fantastic tours, attractions and experiences for their customers.”
