In the state of Virginia, betting and gambling activities are regulated by state laws. As of my last update, here are some forms of betting and gambling that are legal in Virginia:

1. **Lottery:** The Virginia Lottery offers a variety of games including scratch-offs, draw games, and multi-state games like Powerball and Mega Millions.

2. **Sports Betting:** Virginia legalized sports betting in 2020. Sports betting can be conducted both online and through physical sportsbooks at certain locations. The Virginia Lottery Board regulates sports betting in the state.

3. **Casino Gaming:** Virginia has not yet legalized casino gaming, but there has been legislative discussion on the topic. As of now, there are no casinos in the state.

4. **Horse Racing:** While pari-mutuel betting on horse racing is not currently legal in Virginia, the state does allow for historical horse racing machines at certain locations.

5. **Charitable Gaming:** Some forms of charitable gaming, such as raffles and bingo, are allowed under certain conditions.

6. **Social Gambling:** Social gambling, where no house or operator profits from the gambling activity, is generally allowed as long as all participants have an equal chance of winning and the activity is not conducted for profit.

It’s important to note that betting on anything illegal in Virginia is not permitted. This includes activities that are not explicitly legal, such as online poker or unregulated fantasy sports contests.

The legal landscape of gambling can change, so for the most current information, you should check the latest Virginia state laws or consult with legal counsel. Additionally, always ensure that any betting or gambling activities you engage in are conducted through licensed and legal channels within the state.
