The game free ride is a modified version of Let It Ride.
Free ride is found almost exclusively at online casinos.
I have yet to see free ride at a casino in Las Vegas. Most casino table games have a history. They have either been around for a long time or they are a modification of another game that has been around for a long time. Let It Ride is different. Let It Ride was introduced to Nevada casinos in 1993 and quickly became a hit with many table game players.
