Nuzlocke Rules Explained: Complete Guide for Beginners
10 min read · Updated May 2025
The Nuzlocke challenge transforms any Pokémon game into a tense, emotionally charged experience. Two core rules create this shift — but the community has developed dozens of amendments that let you tune the difficulty precisely. This guide explains everything from the base rules to optional clauses, so you can set up your first run correctly.
The Origin of Nuzlocke
The Nuzlocke challenge was created in 2010 by a webcomic artist who documented a brutally difficult FireRed playthrough under self-imposed rules. The name comes from the comic's protagonist. The challenge went viral, spawned thousands of community runs, and is now one of the most popular ways to replay Pokémon games.
The original rules were simple — just permadeath and first-encounter. Everything else in this guide is optional, added by the community over 15 years of iteration.
The 3 Core Rules
Rule 1: Permadeath
If a Pokémon faints, it is considered dead. It must be released (or permanently boxed, depending on your preference). No revives, no second chances.
Why it works: This is the defining rule. It turns every wild battle and trainer fight into a risk calculation. Losing a team member you've trained for 10 hours is genuinely painful.
Rule 2: First Encounter Only
On each route or area, you may only catch the first wild Pokémon you encounter. If it faints or flees before you can catch it, you get nothing from that route.
Why it works: Forces variety. You can't grind a specific Pokémon — you get what you get. This creates attachment to unexpected Pokémon and makes every catch meaningful.
Rule 3: Nicknames (Strongly Recommended)
Give every Pokémon a nickname. This is technically optional but universally recommended by the community.
Why it works: Nicknames create emotional investment. Losing 'Percy the Geodude' hits differently than losing 'Geodude #4'.
Popular Amendments & Clauses
These rules are not part of the original Nuzlocke but are used by the majority of the community. We've marked which ones are recommended for a first run.
Dupes Clause
RecommendedIf the first encounter on a route would be a species you've already caught or seen, you may skip it and encounter the next different species. Prevents your team from becoming all Zubats and Tentacools.
Species Clause
RecommendedYou may only catch one of each species throughout the whole run. Even if you encounter a second Rattata, you cannot catch it.
Shiny Clause
RecommendedIf you encounter a shiny Pokémon, you may catch it regardless of whether it's your first encounter on that route. Almost universally adopted.
Set Mode
RecommendedSet the battle mode to 'Set' instead of 'Switch'. This means the AI does not give you a warning before sending out the next Pokémon — removing a free switch between kills.
No Items in Battle
OptionalYou cannot use Potions, Revives, or other battle items during a fight. Makes every battle more dangerous and forces PP management.
Level Cap
OptionalYour Pokémon cannot exceed the level of the next gym leader's ace Pokémon. Prevents over-levelling your way past challenges.
Setting Up Your First Nuzlocke
- 1
Pick your game
Start with Emerald, FireRed, or Sun/Moon. These have the best early-game pacing and route variety for a first run.
- 2
Set battle mode to Set
In Options → Battle Style → Set. This removes free switching between kills. Essential for a proper difficulty experience.
- 3
Enable Dupes Clause and Shiny Clause mentally
These aren't in-game settings — you enforce them yourself. Decide before you start what your personal ruleset is.
- 4
Nickname everything immediately
Don't wait. Nickname your first Pokémon before the first random encounter. It builds attachment before the losses start.

FAQ
Do you have to release fainted Pokémon?
Releasing is traditional, but "permadeath" can mean permanently boxed and never used again. Both are valid — the community uses both.
What happens if your whole team faints?
That's a Nuzlocke loss — also called a "wipe." Most players either restart the game entirely or start a new run from scratch. Some continue with box reserves.
Can you use the PC box?
Yes, but Pokémon in the box are still "alive." You can rotate team members freely between battles — just not mid-battle.
Is there an official Nuzlocke mode in any game?
No. The Nuzlocke is a community challenge enforced by the player. Some ROM hacks (like Nuzlocke Plus) build it into the game itself.
