Mega Millions jackpots and the odds of winning big will grow starting April 5, as the national lottery rolls out pricier tickets in Colorado and other participating states. Lottery players will soon pay $5 rather than $2 for a ticket — just the second price increase in the 22-year-old game’s history and the first since current rules were adopted in 2017, according to a news release from Colorado Lottery. Jackpots will start at $50 million, up from $20 million, and the odds of buying a winning ticket will increase from about one in 302 million to one in 290 million. “We are excited to bring even more chances to win to Coloradans in April,” Colorado Lottery senior director Tom Seaver said in the release.
