The "Roller Coaster Tycoon" games can be purchased and downloaded on Steam. Other websites, such as Game House, offer free trials of some versions. All four game versions can be found online.
The official "Roller Coaster Tycoon" website directs gamers to Steam to purchase "Deluxe," "Roller Coaster Tycoon 2," "Platinum" and "Mobile." This allows players to get instant access to the games without a disc. Steam and Game House also make it possible to play the game on a wider range of operating systems. Using Steam, for example, allows gamers to play "Roller Coaster Tycoon" on their televisions or mobile devices as well as their computers.
