The Joplin Globe reported that two of the proposals are for casinos in Cherokee County, while the other two are for casinos in Crawford County.
Sally Lunsford, spokeswoman for the Kansas Lottery, said the Lottery Gaming Facility Review Board will have 60 days to recommend the winning bid. The Kansas Racing & Gaming Commission would then have the recommended proposal and the groups which submitted it undergo a background check and have 10 days to approve or reject the recommendation.
Kansas already has three state-owned casinos.
