Frequently asked questions

What is the average slot payback in Missouri?

Missouri slots pay back about 90.3% on average (Aug 2025, per the Missouri Gaming Commission) — a house edge of about 9.7%. Over the long run that is roughly $10 lost for every $100 you cycle through a machine.

Are slots looser in Missouri than other states?

Missouri ranks #13 of the 18 states that publish payback data — among the tightest. Remember the figures come from different reporting periods, so compare them as ballparks, not to the decimal.

Does this mean my machine in Missouri pays back 90.3%?

No. Regulators report averages across all machines in an area, not per game or per machine. Any single session swings far more than the long-run average — that is volatility, and it is usually against you.
