Indiana Law
It is pretty unambiguous in saying that a computer would qualify as an illegal gambling device if it were being used for that purpose. It seems like the code wanted to name every possible game that could be played electronically rather than just making a blanket statement about it, who knows why that would be.
Indiana is one of the harshest states for operators of any kind of illegal gambling. Operators can face up to a Sixth Degree Felony which comes with up to 2.5 years in prison as well as a fine of up to $10,000, or both.
We also know that the gambling laws have been enforced in Indiana with respect to live play, as can be seen in this story where a bar owner got nailed for running a poker game with a minuscule $20 buy-in.
The law also goes on:
to discuss gambling on the internet specifically, so there is no question of the intent to make it illegal for players and operators alike, though it could be a Class B Misdemeanor in the case of players.
Despite occasional arrests for live gambling operations such as the poker game mentioned above, we can find no evidence of any online casino player being arrested for doing that, so we tend to believe players have very little to worry about in this regard.
For that reason...
almost all online casinos that operate within the United States also extend their services to residents of Indiana, and here are some that are available to you below:
