The Colorado Lottery began on January 24, 1983, initially selling only scratch tickets. Its first drawing took place on April 23, 1983.
Colorado Lottery games include Cash 5 (with a 5-of-32 matrix), Pick 3, Colorado Lotto, Mega Millions, and Powerball; it also sells scratch tickets. Colorado has offered fewer jackpot games than most US lotteries even though it began in the early 1980s; Powerball was not available in Colorado until 2001. Colorado joined Mega Millions on May 16, 2010, the same day as South Dakota.
Colorado Lottery revenues are directed, by a state Constitutional amendment Constitution of the State of Colorado#ARTICLE XXVII. Great Outdoors Colorado Program approved by voters in 1992, to outdoor recreation, parks, trails, rivers, wildlife and open space. The Great Outdoors Colorado (GOCO) Trust Fund  distributes 50 percent of Lottery proceeds through competitive grants to local governments and land trusts, while 40 percent is distributed to the Conservation Trust Fund, and 10 percent goes to the Colorado Parks and Wildlife division. [cpw.state.co.us/]. After the GOCO cap is met, proceeds fall into the BEST fund (Building Excellent Schools Today).

Cash 5 began in 1996. It draws 5 of 32 numbers. The jackpot is $20,000.
Pick 3 began in April 2013. It draws 3 of 10 numbers (0-9) and is played by betting amounts of $0.50 to $5.00 on various bet types including Exact Order, Any Order, Front Pair, Back Pair, etc. The jackpot is $2,500.
On January 24, 1989, Colorado Lotto began. Initially it was drawn Saturdays. On July 18, 1990, Wednesday drawings were added. Six of 42 numbers are chosen. The jackpots begin at $1 million; games cost $1. The largest Lotto jackpot in the history of the Colorado Lottery was $27 million, won by Kim Walker of Boulder in 1992.
Since April 2001, Colorado has been a member of MUSL. Powerball's jackpots begin at $40 million; it is drawn Wednesday and Saturday nights.
The largest Powerball jackpot in the history of the Colorado Lottery was won in August 2014. Claude G, a tow truck operator from the small Western slope town of Rifle, won the $90 million prize.
On October 13, 2009 the Mega Millions consortium and MUSL reached an agreement in principle to cross-sell Mega Millions and Powerball in US lottery jurisdictions. Most lotteries with either game began selling tickets for both on January 31, 2010. The Colorado Lottery Commission approved Mega Millions at its meeting in February. Mega Millions tickets have been sold in Colorado since May 16, 2010. The Colorado Lottery has not yet had a Mega Millions jackpot winner.
MatchPlay (ended June 29, 2012)
MatchPlay was drawn on Tuesdays and Fridays. Games were $2 each; each play consisted of three sets of six numbers. The first set could either be chosen by the player, or as a computer-generated "quick pick"; the other two always were quick picks. Six of 38 numbers were drawn. Prizes were won in two ways: "line play" (matching enough numbers in any of the six-number sets), or "combination play" (if enough of the 18 numbers across the three sets were matched. Some $2 plays won in both categories.
An example of a game similar to MatchPlay is Pennsylvania's Match 6.
