The game received 'mixed or average reviews' on all platforms according to the review aggregation website Metacritic. The game allows the placing and deletion of attractions and buildings such as flat rides, food and drink stalls, bathrooms, games, and also contains various minigames to play both in the park and in the game's 'Party Play' mode, along with editing and allowing the players to ride their own roller coasters inside each of the Thrillville theme parks. Like the original game, Thrillville: Off The Rails is a strategy and simulation game about being the park manager of all of the Thrillville theme parks. After some sleuthing, the player discovers that the spy is actually Vernon Garrison Jr, the son of Globo-Joy's president. It soon becomes apparent that a spy somehow worked into Thrillville's employment and is stealing the park's ideas for Globo-Joy. However, he warns the player that they might try to get revenge. The player's Uncle Mortimer (Brian Greene) congratulates the player for making Thrillville one of the best theme parks in the world and for ridding Globo-Joy from the competition.
