The firm hopes to have it on the market in time for Christmas. The big money game show, hosted by Davina McCall, originally aired as a six-day run in May of this year, and averaged over 2.2 million daily viewers.
Eight multiple-choice questions stand between the contestants and the chance to take home £1m in cash.
Contestants have to split their money over answers – or risk it all on one – to survive with the biggest amount they can at the end of the game. Put their money on the wrong answer and the trapdoor opens, sending it falling through the floor.
In addition to watching live, viewers could play along with the show online, with 3.5 million games completed simultaneously in just one week.
This Autumn, the show returns with nine further weekday and weekend episodes scheduled for October and November.
"The Facebook and Twitter activity surrounding the first series has been phenomenal," said Claire McCool, joint founder and marketing director of Drumond Park.
"The concept has, of course, appealed especially to the technology-savvy 16-34 age-group, with a very slight skew towards women. Which means our game, which echoes all the key aspects of the on-screen and online gameplay, will appeal in a big way to both couples and young families looking for something trendy and different to play over Christmas and the New Year."
"We have had a satisfying and successful relationship with Drumond Park in the recent past, with sales through the Deal or No Deal franchise still going strong more than five years since the board game was first developed” says Seema Khan, head of consumer products at Endemol UK.
"What we particularly like about our relationship with Claire and her design and development colleagues is that they are experts at creatively translating the excitement and strategic essences of a particular TV show into a popular game which can provide endless entertainment for the family at home. We are sure that the Million Pound Drop game will be a huge success and look forward to seeing the finished version, which will be going into the shops towards the middle of November."
