The Biggest In-Game Events in Dota 2

As of 2021, Dota 2 has generated more than double the prize money of any other game in eSports. Rightfully, it is the jewel in the crown of eSports betting at online casino sites. When looking back on the history of Dota 2, you might remember the following as some of the biggest events in the game’s history.


Even a fantasy-themed game can care about the festive season. In 2012 and 2013 and 2017 through 2019, Frostivus provided Dota 2 players with a special festive event in which to compete. Of all the years, 2017 is widely regarded as the most memorable. And this is due to players been tasked with a random selection of 10 mini-games out of 30. Those who performed the best were rewarded with perks that were based on their performance.

The Underhollow

In the 2018 iteration of The International, fans were staggered by the introduction of The Underhollow as a battle royale event. As for the format, Valve masterminded a system in which eight teams comprised of three players were forced to fight enemies while attempting to evade one another. Amusingly, the ultimate prize was for the team that was able to sniff out Roshefort, which is the rarest cheese in the world and sought after by Roshan the Immortal.


Even with the use of Dota 2 stats and tips Dota 2 stats and tips a mere mortal cannot hope to ascend to compete with the very best players in the world. Some of those players competed in Diretide, which was introduced as a special Halloween event in 2012. After returning in 2013, Diretide wasn’t hosted again until 2020. The first two iterations challenged the players to collect candy, while the 2020 version had taffy instead. Amusingly, Roshan attacks the players to try and steal their candy.


The International is often the launching ground for Dota 2’s special events, with Siltbreaker also benefiting from this prime introduction. Played out in two acts, Siltbreaker comprised four teams of players in a mini-game that challenged them to advance through special zones with enemies that had to be dispatched. Each zone varies in terms of difficulty and the rewards can get better depending on if the players receive one, two, or three stars.

New Bloom Festival

The New Bloom Festival launched in 2014 and presents the players with a game mode in which they battle the Year Best and mete out as much damage as they can. By inflicting high amounts of damage, the players can boost the standard of their rewards. Some of the in-game items that can appear during the mode are Flinching Firecrackers that can deal 300 damage and Desolator 2s that can reduce the enemy’s armor by 13 hit points for 15 seconds.

Wrath of the Mo'rokai

Owners of The International 2019 Battle Pass were given access to Wrath of the Mo'rokai, which is a game mode that provides the players with a Mo'rokai creature that they can empower with the aim of destroying the ancient of the other team. By feeding Mo'rokai with Essences, the teams can unlock new and more powerful abilities to fight with. Mo'rokai can obtain more health, greater speed, evasive abilities, and more within the Spirit skill tree.

Dark Moon

Dark Moon lasted from January 26 to February 6, 2017. This provided players with a short window in which to defend Selemene's temple from wave upon wave of intruders. Fundamentally, the team consists of five players who must repel hordes during 15 rounds, with the difficulty increasing. The temple is the focus of the mission and is positioned to the north of the map. By saving the eight towers, there can be additional rewards.

Aghanim's Labyrinth

The iconic Aghanim's Labyrinth emerged during The International 2020 Battle Pass and demanded that teams of four battle through a labyrinth of monsters to fight Aghanim as the big boss. Valve adopted the classic roguelike subgenre when devising this dungeon crawl. There are 17 rooms along with bonus rounds and special perks that can be unlocked by progressing through the labyrinth.

The International – eSports Betting

The International Dota 2 Championships is the prime event in the calendar, having been launched in August 2011. Since then, The International has become an annual summer event that is typically hosted in August, though has shifted to October in 2022 to account for the global pandemic, which caused the cancellation of the August 2021 event - that was to be hosted in the Avicii Arena, Stockholm. With eSports betting revenue projected to hit $14 billion in 2020, according to Sports Pro Media, The International 2022 is likely to act as a catalyst.

Those who haven’t been able to qualify for the tournament are off on vacation enjoying the summer. On the other hand, until the championship starts, users can bet on other eSports events or else try their luck at online casino sites where summer vacation themed slots are available to win some extra cash that was missed in the Dota 2 Championships.
