As you head into chapter five of The Centennial Case: A Shijima Story, The Prison of Devices, the gameplay changes up a little from what you're used to. You start with Yoshino bound to a chair and you have to find a way to get her out.

Instead of the standard Incident Phase, Reasoning Phase, and Solution Phase, you'll find yourself switching between Investigation and Reasoning modes as you attempt to escape and save Josui in the process. Here's what you need to know.

Warning – there are spoilers ahead!

Towards the end of this chapter, there will be occasions where you are asked questions. If we have not listed the answers here, it is because they do not matter and have no impact, so feel free to pick whichever you like.

How To Escape The Prison Cell
