I want to be the best on the server
A seasonal Arena, an anything-goes tournament and guild wars.




Your team hunts. You command.
Idle Pokémon MMORPG, free, in your browser and on your phone.
20k+ trainersPick yours and the page lights up what fits you. The other two stay open, because nobody here plays just one way.

A seasonal Arena, an anything-goes tournament and guild wars.

A tournament money can't touch, free auto-hunting and the pass's free track.

Bestiary, decks, shiny and a guild to call your own.
Sigma has a real competitive side: a seasonal Arena, a tournament where anything goes, guild wars and rankings for every kind of trainer.

You build an attack team and a defense team. Your defense fights for you even while you're offline, and every win is worth season points. Climb the leagues, then hold your spot.
You can watch the replay of every fight, see where you lost and come back with a tuned team.
SIGMA TOURNAMENT · ANYTHING GOESEverything you've built counts here: shiny, Pokémon from the market, the team set up exactly the way you wanted. It's the tournament for anyone who wants to prove they have the strongest team on the server.
GUILD WARIn a scheduled window, the two guilds face off duel by duel, six against six. Whoever falls on defense is out, and the points count toward the guild's season.
RANKINGSPokédex, level, power, bestiary and collection. Plus the Dungeon speed clears and the two per-Pokémon rankings. There's room at the top for every kind of trainer.
This tournament is built entirely around balance. Nobody shows up with a bought team, nobody brings a shiny, and levels are equalized. There's no competitive edge you can buy: what decides it is the team you built and the way you play.
And it stands apart from the Arena: its own ranking, its own prize, and nothing carries over from one to the other.
Every knockout and every duplicate Pokémon turns into progress that stays with your account forever. They're different systems, and they add up.

The Bestiary counts how many times you've knocked out each species. Every knockout milestone becomes research points, and the points raise your account's research level.

Each deck asks for specific species, like First Steps or Kanto Starters. You fill the slots with the Pokémon left over in your box.

Two separate areas, with their own maps and the strongest Pokémon of each region.
Kanto's strongest Pokémon, on a map all their own.

At the top of Mount Silver, Johto's strongest Pokémon.

Pokémon, items or the account itself, for money outside the game. The deal is between you, and we don't get involved or guarantee it.
You can have two accounts and move Pokémon, items and gold between them. A third, no.
Every game rule runs on the server: damage, capture, loot and prices. All your browser does is draw.
Nothing to download, nothing to pay to get in. And in Pokémon Master, not even someone willing to spend can buy an edge.
The full rules are in the Terms of Use (the official text is in Portuguese). Whenever they change, a new version shows up in the game for you to read, and you have to accept it to keep playing. Nothing changes behind your back.
The team reads tickets and answers on Discord. A lot of what exists in Sigma today started with a message from a player, sometimes a complaint, sometimes an idea.
PLAYER · TICKET-0000You could have a Pokémon Master tournament for F2P players.
SIGMA TEAMWhat a cool idea. We'll put it in the game!
PLAYER · TICKET-0001I listed my Dragonite on the market and it showed up with the wrong level.
SIGMA TEAMThank you so much! It really was wrong. We sent you the Bug Hunter skin, the one players get for reporting bugs in the game!
PLAYER · TICKET-0002The game freezes when I play on my second monitor.
SIGMA TEAMHi! Another player reported this problem, and we've already fixed it. It'll be live after the next maintenance, which is tomorrow! Thanks a lot for letting us know.
PLAYER · TICKET-0003The guild boss mission never counts.
SIGMA TEAMFixed! The mission counts now. We sent you the Bug Hunter skin!
Sigma becomes a real app (PWA), with an icon on your home screen and its own window, no browser bar around it. Your browser does the installing, in two taps, with no file to download and no strange permission to accept.
Always the same account. What you hunted on your phone is waiting when you open your PC.
It's the browser, not the game, that decides when to offer the install. Sometimes it only shows the prompt after a few seconds on the page. If it doesn't show up, use the browser menu.
No Play Store, no App Store. Nothing is downloaded as a loose file, so there's no "unknown source" warning.
In Chrome or Edge, tap the three-dot menu and choose Install app or Add to Home screen. Sometimes the browser offers it on its own, in a bar at the bottom.
In Safari, tap Share, the square with the arrow pointing up, then Add to Home Screen.
Same idea: the install icon at the end of the address bar in Chrome or Edge, and the game opens in its own window. Firefox doesn't install sites as apps.
Create your account, pick your starter and begin your journey. More than 20,000 trainers have already taken the first step.
