RollerCoaster Tycoon 3D was released on October 16th 2012. It was developed by n-Space for the Nintendo 3DS. While using many assets and engine content from Rollercoaster Tycoon 3, this game reverted to an isometric view and, due to the limitations of the Nintendo 3DS, removed features such as additional scenery and pools.
RollerCoaster Tycoon 4 Mobile was released on April 10th 2014. The game was initially available for iPhone, iPad and iPod touch devices. The game was later released for Android devices (OS 4.0.3 and higher) on October 18th 2014. The game was developed by On5 Games without Chris Sawyer's input (other than licensing). The game returns to the isometric view used in the first two games. The game is built on the freemium model with social media integration. This installment was universally panned amongst fans and critics alike. It was criticized due to Chris Sawyer's absence in the making of the game and the heavy use of microtransactions and wait times.
Released in August 2015, RollerCoaster Tycoon 3: Mobile Edition is an iOS version of RollerCoaster Tycoon 3 developed and published by Frontier and is a faithful port of the original game (tutorial mode, original 18 scenarios for career, and a sandbox).
On December 22nd 2016 a modified port of both RollerCoaster Tycoon and RollerCoaster Tycoon 2 was released for iOS and Android, featuring a single price point for the majority of content from both of the original games. It also features three in-app purchases for Expansion Pack content, based on the two expansion packs from RollerCoaster Tycoon 2 and an editor pack that allows users to create custom scenarios.
