Season 8 Matchmaking statistics revealed a fairly clear pattern in CS2: on most maps, players more often go toward the A site. Out of the eight current maps, five favor the A site in terms of bomb plants, while B leads only on Overpass, Anubis, and Ancient.
Map structure
At first glance, this is just dry bombsite statistics, but in reality it highlights quite well how players perceive map structure in matchmaking. In some cases, the A site looks more straightforward, comfortable, and “default” for attacking play, while in others B offers a better balance between ease of entry, space control, and post-plant play.

On five maps, the A site remains the main point of attack
The biggest skew toward A right now can be seen on Mirage — 58.5% of all bomb plants happen there, while only 41.5% go to B. A very similar picture appears on Dust2, where A is also clearly ahead: 57.5% versus 42.5%.
Next come Cache with 55.1% on A, Nuke with 54.7% on A, and Inferno, where the edge is less sharp but still noticeable — 52.0% versus 48.0%. So even where the balance is almost even, A still more often becomes the final point of attack.
The B site dominates only on three maps
The only exceptions in this picture are Overpass, Anubis, and Ancient. On Overpass, the share of B-site plants is 53.6%, on Anubis it is 53.9%, and the strongest skew toward B is recorded on Ancient — as high as 59.1%.
Ancient is especially telling here. It is the only map in the infographic where B is not just slightly ahead of A, but genuinely looks like the main direction for finishing rounds. That gap shows very clearly how much the gameplay logic of this map differs from maps like Mirage or Dust2.
Why A more often wins out on most maps
On many classic maps, the A site is usually easier to “read” for the average matchmaking player. Often it is a more obvious route, requires less complex coordination on the entry, or simply offers a more comfortable space for finishing the attack after basic mid control or control of key zones.
On Mirage and Dust2, for example, the A site has historically been perceived as a very natural entry point into the round. Not because B is necessarily weaker, but because the path to A looks clearer, more familiar, and simpler for most players in terms of timings and utility usage.
Why B leads on Ancient, Anubis, and Overpass
On Ancient and Anubis, B often gives the feeling of a more direct reward for correctly established control. The team gets a more comfortable area for entry, and the site itself often looks structurally more favorable for finishing the attack than the more complex or longer A scenario.
On Overpass, B has also long been seen as the site where, after good preparation, a round can be closed quickly. There is a clear logic of pressure through water, short, or monster, and for many players this scenario looks simpler than fully breaking A through bank, bathrooms, and long defensive retakes.
Full bombsite distribution by map
According to Season 8 Matchmaking data, the picture looks like this:
Mirage — A 58.5% / B 41.5%
Dust2 — A 57.5% / B 42.5%
Cache — A 55.1% / B 44.9%
Nuke — A 54.7% / B 45.3%
Inferno — A 52.0% / B 48.0%
Overpass — A 46.4% / B 53.6%
Anubis — A 46.1% / B 53.9%
Ancient — A 40.9% / B 59.1%
This stat says a lot not only about the maps, but also about player psychology
These numbers are interesting because they reflect not only site balance, but also the behavior of mass matchmaking. Players usually choose the scenarios that seem either safer, more intuitive, or easier to coordinate even without perfect communication.
That is exactly why A consistently leads on part of the map pool: it does not necessarily mean the site is stronger in a vacuum. Often it simply means that it is better embedded into the habits of the average player.

Several factors
Season 8 Matchmaking data shows a simple but telling trend: in CS2, the bomb is planted more often on A on five of the eight maps, and only Overpass, Anubis, and Ancient break that rule in favor of B.
Most likely, the difference here is determined by a combination of several factors at once: map geometry, ease of entry, post-plant comfort, and how natural a given site feels for mass matchmaking. And that is exactly why this statistic is interesting not only as a number, but as a snapshot of how most rounds in CS2 are actually played.
