Map Data

We’re always looking for ways to make better decisions using data. We previously posted map balance data, and it’s time for an update! Below you’ll find some current statistics for the Active Duty map pool.

Some maps, like Dust2, have not changed much since our previous post. Others, like Cobblestone and Overpass, have changed dramatically. Check out the results below, and let us know what you think!


The round results below show the likelihood of the T (orange) or CT (blue) side winning a round, using data collected over the past month from the highest skill groups in competitive matchmaking.

Overall round outcomes are a broad first-pass, but we can already see some interesting trends – Dust2, Cache and Cobblestone tend to produce similar results.


Overall round outcomes don’t tell us much about what happens in an individual round. To find out how the T and CT side got their wins, we can break down rounds based on whether or not a bomb was planted.

And now some differences emerge. Dust2 and Cache still look fairly similar, the bomb is planted in nearly half of all rounds, though CTs tend to defuse more often in Cache. In Cobblestone, the bomb is planted far less frequently (in this respect, Cobblestone is more similar to Nuke), but is protected by the T-side very effectively.

We’ll continue to share data as we make further adjustments to maps in CS:GO. Take a look, and let us know what you think!

Integrity and Fair Play

Recently, allegations of match fixing in the Cevo Season 5 match between iBUYPOWER and came to our attention. The details are in this DailyDot article:

We can confirm, by investigating the historical activity of relevant accounts, that a substantial number of high valued items won from that match by Duc “cud” Pham were transferred ( via Derek “dboorn” Boorn ) to iBUYPOWER players and NetCodeGuides founder, Casey Foster.

All together, the information we have collected and received makes us uncomfortable continuing any involvement with these individuals. Therefore we will be directing our CS:GO event partners to not allow any of the following individuals’ participation in any capacity in Valve-sponsored events:

Duc “cud” Pham
Derek “dboorn” Boorn
Casey Foster
Sam “Dazed” Marine
Braxton “swag” Pierce
Keven “AZK” Larivière
Joshua “Steel” Nissan

Professional players, their managers, and teams’ organization staff, should under no circumstances gamble on CS:GO matches, associate with high volume CS:GO gamblers, or deliver information to others that might influence their CS:GO bets.

In 2014 we witnessed the explosive growth of CS:GO as a competitive eSport, and 2015 has already started strong. But as CS:GO grows, it’s important to consider the substantial impact an individual professional Counter-Strike player has on the health and stability of their sport. Performing before an audience of millions of fans, they are ambassadors for their game – the strength of professional Counter-Strike comes from the integrity of its players and teams.
