Which of the following is regulated by the Ohio Lottery Commission?

The Ohio Lottery Commission is responsible for overseeing and regulating various forms of gambling within the state, primarily focusing on lottery games. These games include traditional scratch-off tickets, draw games like Powerball and Mega Millions, and various other lottery-related activities. The Commission is tasked with ensuring that these lottery games operate fairly, transparently, and in accordance with state laws, thus providing an avenue for the state to generate revenue while also offering residents a chance to participate legally in lottery activities.

In contrast, horse racing, government-run casino games, and private poker tournaments fall under the jurisdiction of different regulatory bodies or do not fall under any state regulation at all. For example, horse racing is typically regulated by a specific board or commission dedicated to racing, while casino gaming is often overseen by a gaming commission. Private poker tournaments can also operate outside of state regulations if they meet certain criteria, such as being a non-profit event. Therefore, the focus of the Ohio Lottery Commission is specifically on lottery games, making this the correct choice.
