Rat Game – All Achievements Guide, Sudoku Puzzle & Cheese Vault

By Editorial / October 31, 2026 / Achievements / 2 minutes of reading

In this guide, I show how to unlock all achievements in Rat Game, including the hidden achievements and special tasks. I cover the Sudoku puzzle, Dark Magic achievement, and how to open the Cheese Vault. I have organized everything into simple steps to make each achievement easier to unlock.

Self-Explanatory Achievements

Most of the achievements in this game are pretty straightforward and do not require any special explanation. These include:

  • Big Iron on His Hips
  • Escape Artist
  • No Need for an Exterminator
  • Smarter Than a Robot
  • Rats Unite
  • Cold-Blooded
  • Boredom

The Sudoku puzzle is located inside the rat cage. Once you complete it, every player in the current lobby receives the achievement.

This achievement is impossible to get alone, as the Chef automatically wins when you get caught.

Dark Magic

To unlock this achievement, I need to complete two things:

  1. Complete the task of putting the haunted tape into the TV.
  2. Use a lighter to light the small candles on the table in front of the TV. You can do this by pressing Q.

Only the player who lights the candles receives the achievement.

After completing this, the location can also be used as a seemingly permanent revive point for the rats.

Is It Real (Cheese Vault)

To open the Cheese Vault, I need to interact with a light blue book on the bookshelf inside the office. This book is not available on either of the two bookshelves in the entrance area.

Once I interact with the correct book, the leftmost bookcase in the entrance area moves, revealing the entrance to the Cheese Vault.
