Mike’s Room code in DELTARUNE

Mike’s Room code is 6453, which corresponds to the buttons on older cellphones that have the letters M-I-K-E on them to spell out Mike. This code works for most players, but some have reported that codes 5962 and 2345 also work. This may mean that the code will differ for most players, depending on when they access Mike’s Room. There are different theories on how to gather the clues and figure out Mike’s Room code, but 6435 is the most commonly accepted answer. We’ll explain how this works up ahead.

How to get Mike’s Room code in DELTARUNE

After finishing DELTARUNE Chapter 4, you need to load up the save slot that you finished the game with. You’ll spawn in the Dark World with a path available to you that leads you directly to Castle Town. Once in Castle Town, you’ll notice that the only place you can access is the TV building with Mike’s Room. You’ll find the code written next to the door at this point. However, you can also access the door at any time you want by inputting the code we provided (6435).

What’s inside Mike’s Room?

Once inside Mike’s Room, you need to solve a puzzle involving cat statues and a microphone statue. The cat statues blocking your path will disappear once you pet them. But some of them are too tall to reach. Head to the end of the corridor and save the Maus, which then lets you reach higher places and grab them. You’ll find a TVDinner behind the second tall cat statue. You can also pick up any of the hats to put on your character.

This lets you pet the tall cat statues and access the Microphone statue. If you’re confused about the Microphone statue, you can only get it to work by enabling your microphone or by selecting any of the adjustment options available on screen. Then walk up to the door and press the relevant button or speak into your microphone. This will unlock the door, and you can proceed towards the hidden boss fight.

We won’t spoil it, but the gimmick for this boss fight is directly tied to the volume input method you choose here. Best of luck!
