Trick x Logic: Season 1

 is a investigative game developed by Chunsoft and published by Sony Computer Entertainment on July 22, 2010 in Japan for the Sony PSP. The game featured additional cases, each one with a solution DLC that was released a few days after the case DLC. With the shut down of the PSP frontend online shop they can no longer be obtained on the original console. The PS Vita release of the PSP version allows to download all of the content, but to be able to get everything on the original hardware a Sony PS3 is needed (see below for details). The cases were later released as Trick x Logic: Season 2.

How to obtain
The DLCs can still be obtained on the PS Vita release from the Playstation Store or, on the PSP, by purchasing the PSP version on a Playstation 3 system and then transferring them on the handheld console.
