As of my knowledge cutoff date in early 2023, sports betting in Wisconsin is a complex issue due to the state’s laws and the presence of tribal casinos. Here’s a general overview:

**Retail Sports Betting:**

Retail sports betting is available in Wisconsin, but it is limited to certain tribal casinos. These casinos have agreements with the state and the respective tribes that allow them to offer sports betting on their premises. Not all tribal casinos may have sportsbooks, so it would depend on the individual casino and their decision to operate one.

**Online Sports Betting:**

Online sports betting is more complicated. While there have been discussions and efforts to legalize it, as of early 2023, there is no legal framework in place for online sports betting in Wisconsin. Some tribes have expressed interest in offering online sports betting, but this would require further negotiations with the state and changes to state law.

**Legal Considerations:**

It’s important to note that the legal landscape for sports betting can change rapidly due to new legislation, court decisions, or agreements between the state and tribal nations. Always ensure that you are up to date with the latest laws and regulations before participating in sports betting.

**Age Requirement:**

For those who are legally able to bet, the minimum age for sports betting in Wisconsin, as in most states, is 21 years old.

Given these points, if you are interested in sports betting in Wisconsin, you should:

1. Verify the current legal status of sports betting in the state.

2. Check with local tribal casinos to see if they offer sports betting.

3. Be aware that online sports betting may not be legal or available.

Remember to always gamble responsibly and within the bounds of the law.
