Pokémon Showdown is an online Pokémon battle simulator where players can battle other people, create teams, try different formats, and practice competitive Pokémon without going through the usual training process in the main games.
The official site describes it as a Pokémon battle simulator with both randomly generated teams and custom team building.
It is especially useful for players who want to learn competitive battling. You can test strategies, practice switching, try different Pokémon, and play many battles without first raising a full team in a main-series game.
This guide explains what Pokémon Showdown is, how it works, how to start playing, how teams and formats work, and how beginners can improve.
What Is Pokémon Showdown?
Pokémon Showdown is a web-based battle simulator designed around competitive Pokémon battles.
Instead of catching Pokémon, training them, and traveling through a game world, you can go straight to battles.
You choose a format, select or create a team, and battle another player.
The simulator also includes features such as a teambuilder, battle replays, usage statistics, and a damage calculator.
This makes Pokémon Showdown different from the main Pokémon games.
The focus is not exploration or completing a story. The main focus is battling.
How Does Pokémon Showdown Work?
The basic process is simple:
- Open Pokémon Showdown.
- Choose a battle format.
- Use a random team or build your own.
- Click Battle!
- Find an opponent.
- Choose your moves and switches.
- Try to defeat the opposing team.
The official FAQ explains that clicking the Battle! button searches for a ladder match, while players can also challenge specific users.
You do not need to spend hours leveling a Pokémon before trying a competitive battle.
That is one reason the simulator is useful for learning.
Is Pokémon Showdown Free?
Yes. Pokémon Showdown can be played online through its official website.
The homepage provides access to the battle simulator and also offers downloadable versions for Windows and macOS.
For someone who simply wants to try competitive Pokémon, the browser version is an easy place to begin.
How to Play Pokémon Showdown
New players can start with Random Battle.
In a Random Battle, the game gives you Pokémon and sets rather than requiring you to create your own competitive team.
This removes one of the hardest beginner problems: team building.
Once you understand basic battling, you can move into formats where you create your own team.
Step 1: Open Pokémon Showdown
Go to the official Pokémon Showdown website and enter the simulator.
You can play directly in your browser.
Step 2: Choose a Format
Select the format you want to play.
Different formats have different rules, Pokémon restrictions, and strategies.
Step 3: Choose a Team
Some formats provide randomized teams.
Other formats require you to select a team from the Teambuilder.
Step 4: Start a Battle
Click Battle! and wait for the matchmaking system to find an opponent.
Step 5: Make Your Moves
During battle, you can attack, switch Pokémon, use certain battle options, or forfeit when appropriate.
Your opponent is another player, so you need to predict what they may do.
Pokémon Showdown Random Battles
Random Battle is one of the easiest ways for a new player to start.
You do not have to create a team before playing.
Instead, the simulator provides randomized Pokémon and competitive sets.
This lets you focus on battle decisions.
Random formats are also useful for learning because they let players use Pokémon they may not normally choose. Smogon describes random formats as a way for newer players to learn the simulator and competitive Pokémon.
Random Battle is not completely random in the sense that anything can happen with no rules.
The sets and Pokémon are generated according to the format’s rules and available data.
Pokémon Showdown Teambuilder
The Teambuilder is one of the most important features for competitive players.
It lets you create a team before entering a battle.
You can select:
- Pokémon
- Moves
- Abilities
- Items
- EVs
- IVs
- Nature
- Level
- Other format-specific options
A good team is more than six powerful Pokémon.
The Pokémon need to work together.
For example, one Pokémon may provide defensive support while another focuses on damage. A third Pokémon may help control speed or remove hazards.
Good team building starts with a clear plan.
What Are Pokémon Showdown Formats?
A format is a specific ruleset for battles.
Pokémon Showdown supports formats connected with official Nintendo rules, Nintendo matchmaking formats, Smogon formats, and Other Metagames.
This means there is no single way to play Pokémon Showdown.
Different formats can feel like completely different games.
OU
OU, or OverUsed, is one of Smogon’s major competitive tiers.
Its rules determine which Pokémon can be used and which Pokémon are restricted.
The exact rules can change over time as competitive play develops.
Ubers
Ubers is a more powerful competitive environment.
It allows Pokémon that are too powerful for standard OU play.
UU
UU means UnderUsed.
It provides a different metagame from OU with its own usage and restriction structure.
RU
RU means RarelyUsed.
It creates another competitive environment with Pokémon that fit its tier rules.
NU
NU means NeverUsed.
It provides a lower-tier competitive environment with its own Pokémon pool and strategies.
PU
PU is another usage-based tier below NU.
The important point is that these tiers are not simply rankings of how “good” every Pokémon is.
They are systems used to define different competitive environments.
Smogon’s tier system is based heavily on Pokémon usage and competitive rules, and tier placement can change as the metagame changes.
Pokémon Showdown Monotype
Monotype is a format built around one shared type.
For example, a team may focus on Water, Fire, Ghost, or another Pokémon type.
The Pokémon on the team must share a type according to the format’s rules.
This creates a different type of team-building challenge.
A strong Monotype team needs to handle weaknesses while taking advantage of the strengths of its chosen type.
Pokémon Showdown National Dex
National Dex is another popular format.
It is designed to include Pokémon and mechanics that may not be available together in the current main generation.
For example, the format can include older Pokémon and mechanics that have been cut from a particular game’s Pokédex.
The exact rules depend on the generation and format.
Smogon’s current National Dex documentation describes it as a format designed to work with every Pokémon while bringing older mechanics into the modern competitive environment.
Pokémon Showdown VGC
Pokémon Showdown also includes formats based on official Nintendo competitive rules.
VGC focuses on double battles rather than traditional six-versus-six singles.
This means positioning, speed control, protecting teammates, and selecting targets become especially important.
The rules for official formats can change, so players should check the current format rules before building a team.
Pokémon Showdown Ladder
The ladder is where players compete in rated battles.
Winning and losing battles affects your rating.
Pokémon Showdown uses several rating systems, including Elo, GXE, and Glicko-1. The official ladder guide identifies Elo as the main ladder rating.
What Is Elo?
Elo is a rating system used to represent your performance on a ladder.
Your rating normally increases after a win and decreases after a loss.
Pokémon Showdown’s documented Elo system starts players at 1000.
What Is GXE?
GXE stands for Glicko X-Act Estimate.
It represents an estimate related to your expected win chance against an average ladder player.
It is different from simply counting your wins.
What Is Glicko?
Glicko-1 provides a rating together with a measure of rating uncertainty.
This can be useful when comparing players who have different amounts of battle history.
How to Battle Friends on Pokémon Showdown
You can challenge a specific player instead of using normal matchmaking.
Find the player’s username and select the challenge option.
The official FAQ confirms that players can challenge a specific user and choose the format and team they want to use.
This is useful when practicing with friends.
It is also useful for testing a new team before taking it onto a competitive ladder.
Pokémon Showdown Replays
Replays let you review battles.
This is valuable because a loss can teach you more than simply looking at your final score.
When reviewing a battle, ask:
- Did I choose the right lead?
- Did I switch too early?
- Did I miss a speed difference?
- Did I predict too much?
- Did I give the opponent a free turn?
- Was my team prepared for that threat?
- Was there a safer move?
Watching your own replays can help you identify repeated mistakes.
Pokémon Showdown Damage Calculator
Damage calculation is an important part of competitive team building.
The Pokémon Showdown website provides access to a damage calculator.
A damage calculator can help answer questions such as:
- Can this move knock out the opponent?
- Can my Pokémon survive an attack?
- How much damage will a particular item or ability add?
- Is a certain EV spread useful?
- Do I need more Attack, Special Attack, Defense, or Speed?
Do not rely on damage calculations alone.
Battle decisions also depend on prediction, positioning, speed, abilities, items, hazards, and the opponent’s possible moves.
Pokémon Showdown Usage Stats
Usage statistics can help players understand what appears frequently in a particular competitive environment.
This can help when building a team.
If certain Pokémon or strategies are common, your team may need a plan for dealing with them.
However, usage does not automatically mean that one Pokémon is always the right choice.
The metagame changes.
How to Get Better at Pokémon Showdown
New players often try to win by attacking as quickly as possible.
Competitive Pokémon is more complicated than that.
Learn Type Matchups
Know which types are strong and weak against each other.
This gives you a basic foundation for making safe decisions.
Learn Switching
Switching is a major part of competitive battling.
The official competitive introduction explains that switching happens frequently because human opponents actively respond to your strategy.
A good switch can turn a bad position into a strong one.
Understand Speed
Knowing which Pokémon moves first can completely change a battle.
Speed stats, boosts, Choice Scarf, priority moves, paralysis, and other effects can matter.
Avoid Predicting Too Much
Prediction can win battles.
But predicting every turn can also create unnecessary risk.
Sometimes the safest move is simply the strongest reliable move.
Build Around a Clear Strategy
Do not select six Pokémon randomly.
Think about what your team wants to accomplish.
You may build around:
- Offensive pressure
- Defensive play
- Speed control
- Entry hazards
- Weather
- Setup sweeping
- Status effects
- Balance
Pokémon Showdown Rules
Pokémon Showdown has rules for both gameplay and community behavior.
The official rules require users to respect other people and prohibit cheating, impersonation, sexually explicit content, piracy, and other prohibited behavior.
Chatrooms may also have their own rules.
Reading the rules is important before becoming active in the community.
Is Pokémon Showdown Safe?
Pokémon Showdown is an online multiplayer environment, so normal internet safety matters.
Do not share passwords or private information with strangers.
Be careful with links and messages from other users.
The official FAQ also provides reporting and appeal procedures for users who encounter rule violations.
