As players progress through Chapter 4 of Deltarune, they eventually discover a peculiar TV building in Castle Town. Within this building lies a locked area simply labeled “Mike’s Room.” Unlike many parts of the game that are unlocked through narrative progression, Mike’s Room presents a unique barrier—a keypad that demands a code. For those wondering how to unlock this door and what secrets it hides, this guide explains everything you need to know.
Where to Find Mike’s Room
Mike’s Room is located in the newly accessible TV building in Castle Town, which becomes available after completing Chapter 4. When you reload your save after beating the chapter, you’ll spawn in the Dark World with a path that takes you back to Castle Town. At this point, the door to Mike’s Room is interactable and asks for a four-digit code.
You can also attempt to enter this door earlier in your playthrough, but you’ll need to know the correct code in advance.
Mike’s Room Code: What It Is and How It Works
The code to unlock Mike’s Room is 6453.
This number corresponds to the letters M-I-K-E on a traditional mobile keypad:
- 6 = M
- 4 = I
- 5 = K
- 3 = E
Inputting 6453 will open the door for most players. However, there are reports that alternative codes such as 5962 or 2345 have worked for others. This variation suggests that the code might be instance-specific or influenced by your game state, though 6453 is the most consistently verified across player experiences.
The game does not provide direct instructions for this code, leading to widespread theories in the community. Some believe it’s hinted at through environmental clues or linked to prior phone-based puzzles like the parental lock system. While there’s no confirmed in-game breadcrumb trail yet, the community consensus is that the “MIKE” letter-to-number translation is an intentional design.
What Inside Mike’s Room?
Gaining entry is only the beginning—Mike’s Room itself holds both environmental puzzles and the path to a potential secret boss.
Here’s what to expect:
- Statue Puzzle with Cats: You’ll encounter a corridor blocked by cat statues. Some of these can be petted to disappear, but others are too tall to reach.
- Save the Maus: At the far end, you’ll find a trapped Maus. Freeing it allows you to interact with the tall statues.
- Rewards: You can find a collectible item called “TVDinner” behind the second tall cat statue, and decorative hats you can wear.
- Microphone Statue Mechanic: The final obstacle involves a large microphone statue. You can activate it in one of two ways:
- Enable your computer’s microphone and speak into it.
- Choose one of the on-screen input options to simulate volume.
What Comes After: Secret Boss Connection
While details remain intentionally vague, strong evidence suggests that Mike is connected to Chapter 4’s secret boss encounter. Players who solve the puzzle and interact with the microphone trigger a hidden fight that is considered one of the most challenging and unique in the game so far. The fight’s mechanics even change depending on how you handle the microphone interaction, such as input method and volume.
Final Thoughts
Mike’s Room stands out in Deltarune Chapter 4 as a cleverly hidden secret blending community collaboration, retro keypad logic, and inventive puzzle mechanics. Whether you’re in it for the lore, the puzzle-solving, or the thrill of uncovering secrets, discovering and entering 6453 is a satisfying moment. As the game continues to evolve, players are likely to uncover even more layers to Mike’s character and his role in the unfolding story.
