How to win

GG concedes the match — Type "gg" in team chat to start a concession countdown; confirmed concessions are irreversible.
Tiebreaker Order — Ties broken by head-to-head record, then game score differential, then time rating.
Destroy the Ancient — Destroy the enemy Ancient to win; no time limit, play until it falls or a team concedes.
BO2: 2 points for sweep, 1 point each for draw; BO3: First to 2 game wins advances; BO5: First to 3 game wins
GG concedes the match — A team may call "GG" to concede the match.

The game

Each team consists of 5 active players and 1 coach; Standard positions: Carry (Pos 1), Mid (Pos 2), Offlane (Pos 3), So…
Registered in DPC, no active Valve ban; regional roster locks apply in-season.

Cultural norms — not in the rulebook. These are widely understood traditions and expectations among experienced Dota 2 players. Not enforced by referees; enforced by the game’s community. Rules marked ⚡ Contested are genuinely debated even among veterans.

🚨 Cardinal Rule— Serious violation — may trigger retaliation or social exclusion

Do not abandon a game, even when losing badly
— Leaving a match before the ancient falls is a serious social contract violation regardless of how lopsided the score is. Beyond Valve's automated Low Priority penalty system, the community applies strong normative pressure against abandonment. Feeding and then leaving compounds the offense significantly.[1]
Do not intentionally feed (die repeatedly on purpose)
— Deliberately running into enemies to hand them kills—whether from frustration, tilting, or to sabotage teammates—is among the most condemned behaviors in Dota 2 culture. The unwritten expectation is to play earnestly until the ancient falls regardless of game state. Valve's grief detection is separate from, and secondary to, the community norm.[1]
Fountain hooking was taboo (historical)⚡ ContestedProfessional play
A technique exploiting Pudge's hook combined with displacement abilities to pull enemies directly into the fountain for instant, unavoidable kills. Though technically within the ruleset, the community broadly condemned it as exploiting an engine oversight rather than legitimate play. It gained widespread notoriety in high-stakes professional matches at The International 3 (2013) and Valve subsequently patched it out.

1. Introduction

Dota 2 is a multiplayer online battle arena (MOBA) game developed by Valve Corporation. Two teams of five players each select heroes from a pool of over 120 and compete to destroy the opposing team's Ancient, a core structure in their base.

Competitive Dota 2 is anchored by The International (TI), one of the most prestigious esports tournaments in the world, featuring prize pools that have exceeded $40 million. The professional circuit includes regional leagues (DPC), Major tournaments, and The International.

This ruleset covers the standard competitive format used in Valve-sanctioned events and tier-1 professional tournaments.

⚠️ Strong Expectation— Most experienced players will take notice and be upset

Never type 'GG' in all-chat while the game is still in progress
— Typing 'GG' in all-chat before the ancient falls—especially when winning—is considered disrespectful taunting. The custom is to use GG only when the game is definitively over as a mutual acknowledgment, not as a premature victory declaration. Using it mid-game signals poor sportsmanship and invites condemnation.(Distinct from typing GG in team chat to signal teammates to call it; the taboo applies specifically to all-chat taunting while the outcome is still contested or not yet conceded.)[1]
Pause the game immediately when any player disconnects
— When a player—teammate or opponent—loses connection, the expectation is to pause at once and allow time to reconnect. Refusing to pause, or quickly unpausing while an opponent is disconnected, is a serious breach of etiquette. The norm holds even in pub games and is near-absolute in organized competition.(Tournament administrators typically codify this formally; the norm extends downward into all ranked play.)[1]
Supports must not take farm (last hits) from the carry in lane
— Support players are expected to deny enemy creeps and protect the carry without taking last hits on allied creeps. Stealing farm as a support—depriving the carry of gold and experience during the laning phase—is one of the most commonly cited etiquette violations in Dota 2 and is treated as a fundamental failure of role responsibility.[1]
Only pause for legitimate reasons; do not abuse the pause system
— Each team receives a limited number of pauses intended for genuine emergencies—crashes, disconnects, or urgent real-world issues. Using pauses frivolously, pausing at tactically disruptive moments (mid-teamfight), or spam-pausing to tilt opponents is considered a serious abuse of a trust-based system.(Tournament rules codify acceptable pause usage formally; the norm against abuse extends into pub culture where referees are absent.)[1]

Version History(4)

2026 Competitive SeasonCurrentJan 1, 2026

Auto-detected content change during sync (commit 06ffb34)

2011 The International First Tournament (Gamescom)Aug 1, 2011

Foundational competitive milestone in Dota 2's history. To ensure that enough Defense of the Ancients players would take up Dota 2 and to promote the game to a new audience, Valve invited sixteen accomplished Defense of the Ancients esports teams to compete at a Dota 2-specific tournament at Gamescom in August 2011, which later became an annually held event known as The International. The 2011 inaugural TI predates Dota 2's 2013 public Steam release by two years (the game was still in private beta), making TI one of esports' rare flagship tournaments to launch alongside an unreleased game. The International has since become the highest-prize-pool annual esports tournament in the world (community-funded via Battle Pass / Compendium contributions).

2013 Dota 2 Steam ReleaseJul 9, 2013

Foundational game-release milestone. Following nearly two years of beta testing, Dota 2 was released on Steam for Windows on 9 July 2013, and for OS X and Linux on 18 July 2013. The 2013 release made Dota 2 freely available globally on Steam, transitioning the game from beta-invite-only access to open public access. Every modern Dota 2 competitive convention (Pro Circuit, regional leagues, Major tournaments, The International championship cycle) has built on the post-2013-launch competitive ecosystem. The 2-year beta phase preceding launch (2011-2013) included the inaugural The International tournament at Gamescom 2011, making Dota 2 unique among major esports as a game whose flagship competitive event predates its public release by two years.

2016 Dota 2 Patch 7.00 "The New Journey"Dec 12, 2016

Most consequential modern gameplay-rule rework in Dota 2's history. In December 2016, Dota 2 was updated to gameplay version 7.00, also known as "The New Journey" update. The 7.00 patch introduced Talents (level-bound heroes choices replacing traditional skill-tree progression), reworked the map with new outposts and shrines, added Monkey King as the first new hero developed for Dota 2 (rather than imported from DotA Allstars), and overhauled item and ability balance. The 7.x sequence has been the active gameplay-rule framework ever since, with subsequent patches (7.20, 7.30, 7.34, 7.36) building on the 7.00 foundation. Every modern professional Dota 2 match operates under post-7.00 rules.
