Summary
Pokemonisn’t a franchise that’s particularly based on difficulty. Although several critics and long-time fans note a drastic change in difficulty between the release ofPokemon Black & White 2andPokemon X & Y,this change hasn’t been acknowledged in the games themselves.
Partially due to the change in difficulty in the core series games, but even before then, experienced players have been crafting ways to take the formula of any standardPokemongame andmake it exponentially more challenging. This phenomenon has become huge online, with players showcasing new, interesting sets of rules to make the base games harder, as well as creating strategies to overcome these self-imposed challenges. Here are the best challenges to make anyPokemongame a bit harder.

Updated June 17, 2025 by Ben Painter: The newer entries in the Pokemon franchise are easier compared to the older generations. Enemy teams aren’t as strong, better Pokemon can be found easily and mechanics such as all Pokemon receiving EXP just make the game a breeze. There are several challenges that gamers can do to make the games more difficult. The most popular is a “nuzlocke.”
But there are countless other twists that players can add to the Pokemon experience, which will add a whole new dimension. This may also be an option for players who are anxiously awaiting the release of the latest entry in the franchise,Pokemon Legends: Z-A. This update adds five new entries on how gamers can challenge themselves in Pokemon.

1Nuzlocke
Pokemon With Imposed Rules
Nuzlocke rulesets are often used as thebase set of guidelines for any challenge inPokemon. This includes rules like nicknames, catching the first encounter on every new route or area, set battle style, and dead Pokemon.
Over the years, Nuzlocke challenges have evolved to adopt even more rules, such as level caps anditem restrictions, which is known as a ‘Hardcore Nuzlocke’. The term Nuzlocke stems from the Pokemon Nuzleaf and theLostcharacter John Locke, which were merged in an online comic series. There are a lot of other rules that can be applied to this challenge, but the basic rules described here are considered the standard.

2One Color Only
Use Pokemon That Are Mainly One Color
Pokemon can split up into a lot of different categories: what they’re based on, their type, what moves they learn, etc. One of thesecould be a Pokemon’s color. Each ‘mon is assigned a color that fits them the best, and it can be viewed from the Pokedex in certain games.
The color assigned isn’t always accurate, as Charizard is categorized as a red Pokemon even though it is orange. Using Pokemon that are only one color poses a challenge as it will limit the amount of Pokemon the trainer can use, and this can also be made even harder with the application of Nuzloke rules.

3One Animal Only
Use Only Pokemon Based On Certain Animals
A Pokemon’s origins come from various things: objects, plants, and myths. Mainly, they are designed to be based on animals, so this is the theme for this challenge. Gamers could only use one Pokemon based on a certain animal; the dog is a good example of this, as there are a lot of dog-like Pokemon, such as Arcanine, Lucarion, and Lycanroc.
But there are countless ways this can be done. Rabbit Pokemon, mouse Pokemon, or cat Pokemon would work really well. This could even be changed to Pokemon based on plants, Pokemon based on objects, or Pokemon based on food. There are a few ways this style of playthrough could be achieved in any of the many Pokemon games across all nine generations.

4Version Exclusives Only
Use Pokemon That Exclusive To The Version That Is Being Played
To the dismay of some fans, each Pokemon game has two versions, and there areversion-exclusive Pokemon that can only be obtained in either version. This makes completing the Pokedex a pain, as gamers will need both copies to catch every creature.
However, this challenge aims to only use those Pokemon that will only appear in one version. UsingPokemon Rubyas an example, there are only four non-Legendary Pokemon that are solely available in Hoenn. Using so few Pokemon throughout a playthrough is set to be a real challenge, and this can even be boosted with Nuzlocke rules.

5Ditto Only
Use Only The Transforming Ditto
Ditto is a very interesting Pokemon as the only move it can learn is Transform, which does what it says on the tin and transforms into the enemy Pokemon. It also learns the moves that the Pokemon knows but limits this to 5 PP, and the change is not permanent as, after the battle, it becomes a Ditto once again.
This challenge takes this unique Pokemon and makes it the main character. A Ditto-only run will pose a serious challenge, as gamers will have to use all of their Pokemon knowledge to work out ways to use Ditto and its one move. Gamers can use just one Ditto or a team of six to make it a little less difficult.

6Smeargle Only
Use Only This Unique Pokemon In The Playthrough
In a similar vein to the Ditto-only challenge, this version uses Smeargle, another unique Pokemon in the franchise. The Painter Pokemonis the only ‘monthat can learn the move Sketch, which is what this challenge is all about.
Sketch lets the user permanently learn the last move used by the opponent, which means that Smeargle can essentially learn every move in the game (except for a few). Gamers will have to strategically plan their run with a team of six Smeargle and look for Pokemon that will have useful moves that will aid in progressing through the story and the end goal of defeating the Elite Four & Champion.

7Complete Series Playthrough
Go Through Every Pokemon Game From Start To Finish
The difficulty in this challenge stems from the grind it takes to play through the complete franchise of 37 individual mainline games. This can be broken down into just one game of each version (i.e. justPokemon Diamondout ofDiamond,Pearl&Platinum).
Completing every Pokemon game will take a lot of hours, and it will be insanely tedious as some versions of the games are the same, with minor tweaks to characters and Pokemon found. Playing with different Pokemon in each game will cause an issue as gamers will have to plan which Pokemon they are going to use for each different playthrough. However, this is made easier with new Pokemon introduced in each generation.

8No Super Effective Moves
Gamers Are Not Allowed To Use Moves Which Will Deal 2x Damage
The best strategy for battles in Pokemonis to use movesto which the enemy Pokemon are weak. For example, Water-type Pokemon are weak to Grass and Electric moves like Razor Leaf and Thunderbolt, respectively.
But, in this challenge, these are banned. Gamers will have to pull out every trick in the book to get a real edge on their opponent, who will use a super-effective move if they can. Steel types will cause a big issue in this run as they have just four different types, which will cause regular damage. A tip for this one will be to use Normal-type moves as much as possible, as they can’t deal super-effective damage to any type anyway.

9No STAB Moves
Using Moves That Match The Type Of A Pokemon Are Banned
STAB stands for Same Type Attack Bonus. When a Pokemon uses a move that is of the same type as itself, it gains a 50% increase in its power. However, in this challenge, it is banned. Generally, Pokemon learn moves of their typing as they level up, so this causes some issues.
Players will need to find some clever TM’s and use Pokemon, which have varied movesets such as Hitmonchan (who can learn the elemental punches, and Starmie (who can make use of Thunderbolt and Ice Beam(. There are a lot of Pokemon who can learn a lot of varied moves, so this challenge is not too hard. But having no 50% boost to attack will need to be worked around for the harder battles in the franchise.
10Egglocke
Using Only Pokemon Which Have Hatched From An Egg
A common way to do an Egglocke is to get some friends tosend you some eggsand place them inside the PC box. Play the game as normal but trade in any caught Pokemon for the eggs inside the PC. Some Pokemon may be powerhouses, but some unkind chums may gift some awful Pokemon. Nuzlocke rules of only one Pokemon per area are commonly applied to an Egglocke to limit the amount of egg Pokemon the player can acquire.
Another way to do this challenge is to only use Pokemon hatched from in-game eggs which are given out in games. However, this challenge may be tricky to get started.
