There's actually three casinos in Niagara falls. There is the Seneca Niagara Casino on the US side, and on the Canadian side, there is the Fallsview Casino and Casino Niagara. Which one do you want or maybe all three? Casino Niagara is the oldest, followed by Seneca Niagara, and the Fallsview is the newest. Both Canadian casinos share chips, but the Fallsview came out with their own when they opened even though you can use chips from Casino Niagara there and vise versa.
