Struggling with repetitive shifts in That's Not My Neighbor? You want to torture your friends with a Doppelganger that looks just like them, or you keep dying to the unfair "Killer Clown" card game in Nightmare Mode. Without Custom Mode, the game ends too soon. And without a strategy for Card Mode, that creepy clown will end your Rank S run in seconds. These features are locked behind the Remaster version, and many players don't even know they exist or how to win them. This guide unlocks both. We will show you step-by-step how to create your own neighbors in Custom Mode (Remaster required) and reveal the 95% win-rate strategy to beat the Killer Clown.

First things first: Custom Mode is a premium feature. While the browser versions are fantastic for quick arcade runs, this specific creative tool is exclusive to the Remastered Version on Steam or Itch.io.
If you are searching for the "Create" button on the web version and can't find it, that is why. The developer, Nacho Sama, originally intended to add this to the 1.2.0.0 update of the original version, but due to technical difficulties, it was scrapped and moved exclusively to the Remaster.
Do I need to beat the game? Contrary to popular belief, you usually don't need to grind through the entire Campaign to access this. In the Remaster, Custom Mode is confirmed to be playable and generally unlocks after you have familiarized yourself with the core mechanics (like completing the Tutorial or your first run).
Once unlocked, a new badge labeled "Custom Mode" (formerly known as "Create Mode" during development teasers) will appear on your Main Menu.
This is where you transition from a helpless Doorman to an all-powerful Game Master. The Custom Mode allows you to populate the building with up to 24 residents. Since the apartment complex follows the standard structure of 3 floors with 4 apartments each (12 total apartments), you can create a full house of occupants and their Doppelgangers.
The game provides base assets from the canon characters. When you start creating a neighbor, the game initially randomizes the assets, giving you a chaotic starting point that you can then tweak freely.
Template Type | Description | Creative Tip |
Standard Resident | Uses base bodies like Roman or Gloria. | Perfect for creating "Subtle Doppelgangers" that look 99% human but have one tiny flaw. |
Monstrous Base | Uses Nightmare Mode assets. | Great for "Troll Maps" where everyone looks like a monster, but you have to check their papers. |
You have full control over the facial features. The goal is to make them distinct enough to be memorable, or similar enough to confuse your friends.
A Doppelganger isn't just a scary face; it's a bureaucratic nightmare. You can edit the text on their Entry Request and ID Card.
Once you have designed your cast, you populate the building.
The community for That's Not My Neighbor is thriving, and sharing your creations is half the fun.
While the Wiki doesn't detail the exact file path, standard practice for the Remaster involves exporting your custom configuration (usually a .json file or a code string) directly from the Custom Menu.
To play a map made by a famous YouTuber or a friend:
Now, let's talk about the feature that ends more Nightmare runs than anything else: Card Mode.
This is not a standalone menu option. It is a secret game mode triggered by the Nightmare Clown (a cameo from Nacho Sama's other game, Unlikely) at the end of a Nightmare Mode run.
It takes place in a dream sequence. You wake up at a small table opposite the Clown.
Many guides get this wrong. It is NOT a simple "High Card Wins" game like War. The rules are more strategic, similar to Uno or Crazy Eights, but with a deadly twist:
The key to winning isn't just having high cards; it's managing your hand size to avoid the "5-Card Death Limit."
Card Rank | Value | Strategic Use |
King (K) | 13 | The ultimate blocker. It forces the opponent to play a matching suit or an Ace. |
Ace (A) | 1 | The "King Slayer." Save this specifically to counter the Clown's King. |
Mid (5-10) | 5-10 | Safe fillers. Use these to bridge the gap between low and high numbers. |
Since the Clown is AI, he follows logic. He will try to play his lowest valid card to save his high cards.
You can look for these two versions on our platform Ozgames.io.
Custom Mode is your canvas for chaos, allowing you to breathe new life into the game with endless creativity. Meanwhile, Card Mode is the ultimate test of your nerves. By understanding the specific rules, especially the "Ace beats King" and "5-Card Limit", you can turn a game of luck into a game of skill.
Whether you are designing a map where every neighbor is a "Peach" clone or staring down the Nightmare Clown in a death match, mastery is within your reach.

Custom Mode is exclusive to the Remastered Version (Steam/Itch.io). It is usually available immediately or after completing the tutorial.
No. Card Mode is a mini-game that occurs within Nightmare Mode, involving the Nightmare Clown.
You must be the first to empty your hand. You can play a card if it is higher/equal value OR same suit. Don't forget: Ace beats King.
The browser versions are typically the Demo or Arcade builds. The Custom Mode feature was confirmed only for the Remaster version.
If the Clown wins 2 out of 3 rounds, he breaks the glass and kills you, ending your run instantly.
