Scientific Games will continue to serve as the primary instant games provider to the Colorado Lottery under a new six-year contract.

The new contract came into force on July 1st and covers instant game planning, research and analysis, marketing services and sales support, and includes the option to extend by two additional years.

"The Colorado Lottery has proudly re-invested more than $3 billion to Colorado's great outdoors, and Scientific Games has been instrumental in helping us achieve our proceeds goals," Colorado Lottery director Laura Solano said.

"They've been a great partner for more than 30 years, and continue to demonstrate a commitment to the integrity and quality of our Scratch games."

The contract renewal continues a relationship that dates back to 1983, and was most recently extended in September 2014. 

Over the course of the previous contract, which was in force during Scientific Games' 2011 to 2016 financial years, instant games sales grew by 19 per cent. Crossword extended play games proved particularly popular, generating $819.4m in retail sales, while branded instants such as Walking Dead and Atari titles generated an additional $183.2m.

"We have collaborated with the Colorado Lottery to develop a very strong portfolio of instant games, and we are honored to have the opportunity to continue our great work together for another six years," Scientific Games senior vice president of instant products John Schulz commented.

"We remain focused on the research and analysis that help us create games Coloradans love, and on the lottery's mission to grow returns to the state for programs that protect its most valuable resources."
