Test Your Audio: Plug into external speakers so the "B-12!" can be heard in the back row.
Check your local laws. While the software is just a tool, using it for "real money" games often requires specific gaming licenses depending on your state or country.
If you choose a downloadable software or mobile app, you usually only need the internet for the initial download. After that, you can play offline in a park, community center, or basement.
Most free downloads are ad-supported or offer a "lite" version of a paid app. For a standard home game, the free versions are almost always sufficient.
