Two years ago we examined a data sample of 8 million brood war replays from repmastered. If you're seeing this for the first time, I highly recommend reading the older post first.

The data sample has grown to 70 million replays, so it seemed like a good time to revisit. There are two parts to this. The first part is similar to what we looked at last time, i.e. how win rates for specific match-ups develop during the game, just with more data and split by map. This is now possible due to the much bigger data sample.

The second part is new, wherein we'll take a look at how balanced spawn locations are. We'll look at this both for mirror match-ups and for non-mirror matchups.

Did you ever wonder what the best spawn is as Terran in TvZ on Fighting Spirit? Did you ever feel like your timings are much more crisp when you spawn at 12 o'clock with Zerg on Dominator? Is there a difference between vertical and horizontal entrances at the natural expansion for Protoss in PvZ? Could it even be that some specific spawn locations are so much better, that an otherwise disadvantaged matchup becomes advantageous? Let's find out.

Data
+ Show Spoiler +
The dataset comprises roughly 70 million 1v1 games played since the start of 2018, but by far the biggest part came in during the last 2 years. This is perfect, since we should care much more about recent games on new ladder maps, than what happened long in the past.

tbh the "70 million" is a lie at this very moment, because I used only a data set of ~21million replays (up to february 2025), but it should be updated to the full data set in the next few days. 70 million are available at repmastered so this is what we're going with for the thread title


The information from the dataset doesn't provide complete information from a replay but rather some extracted data. Build order or income details are not available.

The dataset did include:

  1. Player races
  2. Game winner
  3. Game duration
  4. Spawn locations
  5. Player MMR



To refine the dataset, a few filters were applied:

Game duration > 2 minutes
Exclude draws
Exclude games with afk players
Exclude games on fastest maps and similar
Exclude games on maps with fewer than 100.000 games

See below for a map frequency histogram. The rectangle-name-map is FS1.3 and FS1.4, since it's the only map with a korean name.

Player population
Here we see how the ladder MMR is distributed between the players of different races. The vertical lines represent the mean of the distributions.

In the raw counts + Show Spoiler +
[image loading]
, we see that overall there are slightly more protoss players than zerg or terran players, but the difference is not that big (~15%). The average MMR is very slightly higher for zerg.

We can also look at this after normalizing each of the distributions: + Show Spoiler +
[image loading]
. Basically this is what it would look like, if there were exactly as many players of each of the races. There's not too much insight here, since the distributions almost perfectly overlap. If anything, we could say that the skill variance between players of a given race is pretty similar for all races.



Part 1, Win rates vs. game time

These distributions were created in the same way as described here. I feel like the write-up and the discussion in the comments in the old thread on what we see in the plots was sufficient, so I'll leave it at this.

PvT, overall

You can find a lot more data on a per-map basis here. Not sure what's the best way to share this, but google drive makes it easiest for me to update.

When looking at these win rates vs time on a per-map basis, to me there's quite a bit of variation. While most maps tend to follow the very same trend as we see on the average for all maps, the deviations are actually quite significant. Especially when we compare two maps to each other, we can tell that specific builds or timings differ in their relative strength depending on the map. For example consider Eclipse and Neo Dark Origin, both 2-player-maps:


+ Show Spoiler +
[image loading]


[image loading]


To me, the most striking difference is the mid-game strength of Terran. While we see that Terran dominates the match-up as usual at ~9-16 minutes, this is much more pronounced on Eclipse, in agreement with the consensus that Eclipse is a particularly hard map for Zergs to get into a late-game 4gas situation.

Now if we go into specifics and smaller details, we can consider that the rush distance on Eclipse is a bit longer compared to most other 2-player-maps, so things like 2-Rax sunken busts are a bit weaker.

We can see this at the peak around 5-6-7 minutes, where the win rate shoots up for Terran. Note the peak is both lower and later in the case of Eclipse: the sunken bust hits later and is less potent. On the other hand, when we look at what happens around 7-8 minutes, we see a dip caused by Mutalisk timings. We can instantly tell that, whatever the reason, Mutalisks hit much harder on Neo Dark Origin, compared to Eclipse.

I think generally this is the most important takeaway and how this data can be used. You can consult these plots to see whether a particular build is comparably stronger or weaker on a specific map.




Part 2, Win rates by spawn location

Now, to the new and more interesting part. In the following, we'll be looking at win rates for a specific spawn, on a given map, on a given matchup.

So each of the plots will have exactly that information: map, matchup, and how the spawn locations differ between each other.

Consider the example of ZvZ on Dominator: + Show Spoiler +
[image loading]


We can see that the 12 o'clock is by far the best spawn location. The red-green-color gradient at the bottom is telling us whether a spawn is at advantage or at disadvantage. For the case of mirror match-ups, this is the easiest, since the expected win rate everywhere should be 50%. So a deviation below that will turn into red, and anything above becomes green. At the very center, close to 50%, the color scheme becomes white, which means that, the more color you see on this plots, the more overall imbalance there is. If you see a plot with very little color, this means that all spawn locations are very similar to each other.

Next, let's consider another example, TvP on Polypoid. + Show Spoiler +
[image loading]


The only difference here is that we no longer use the 50% as benchmark for a "balanced" spawn. Instead, the benchmark is the overall win rate (for this matchup) for this map. For example, Terran has an overall win rate of 51.1% in TvP on this map, as given in the central text box. Thus to evaluate the spawn, we consider the difference to this 51.1% to figure out what the best/worst spawns are.

Another difference in this particular example is that an MMR bracket was selected, as shown in the info box. I'm using the same definition for this as last time. + Show Spoiler +
A match-mmr is determined by taking the average MMR of the two players (initial MMR values before the match was played). Several brackets of games are defined and compared. Additionally, a requirement is imposed on the max difference of player MMR, to ensure only games of a meaningful skill difference are taken into account.

I generally wanted to see how this imbalance for spawn locations behaves as we examine players of different strength. Currently, there are three brackets:

- all players
- match MMR > 1900
- match MMR > 2100

If deemed relevant I can adjust these, but it seemed sufficient so far.



At last, note that while previously it was sufficient to e.g. look at a graph for PvT to understand both the perspective of the Terran and the perspective of the Protoss, for this map-and-matchup-and-spawn-specific plots we must consider these independently. So we end up with 9 perspectives which need to be considered: zvz, tvt, pvp, pvz, pvt, tvz, tvp, zvp, zvt.


Now we can dive into the actual results - let me start by saying that I was very surprised by what I saw.

For a given map, more often than not, the spawn location seems to actually be the most deciding factor. I expected the differences to be maybe at the order of a few percent, but the actual differences are often above 5% and sometimes even at 10%. Isn't that crazy? Two years ago, we also examined at how matchup win rates depend on cross-spawn vs close-spawn on 4-players map, and there is a significant and measurable effect. However, pretty often it is completely dwarfed when compared to the influence of the specific spawn.

If you think about how many of the recent balance discussions here on ZvP centered on matchup differences of like 48-52%, but its actually more like

"yeah so for PvZ, as Protoss on Fighting Spirit, you just need to spawn top right and you are miles ahead"

and this usually persists throughout the MMR brackets or becomes even more severe. Just look at this:
+ Show Spoiler +

What the heck? So when I first saw some of these, my first thought was that something might be wrong with the data or my methods, so I started checking things to confirm everything works as expected and I didn't mess up. I've arrived at a few cases where it should be easy to tell was is supposed to happen, and it does happen every single time. Thus I'm inclined to believe what we see in the data is overall correct. Let me show you these cases.

case 1, FS1.3 -> FS1.4

Luckily, there are a few maps in the pool, where just tiny changes were applied to specific spawns. For example, when we went from FS1.3 to FS1.4, the one relevant change was the layout of the minerals on the left-side spawns. It has become known that right-side spawn was mining faster, so we switched to "L"-shaped mineral layouts on the left side. This difference in mining rates is most relevant for Zerg, since they mine with the least amount of drones.

FS1.3, ZvZ
+ Show Spoiler +
[image loading]

[image loading]

[image loading]


FS1.4, ZvZ
+ Show Spoiler +
[image loading]

[image loading]

[image loading]


As expected, in each of the brackets we see the advantage of right-side spawn shrinks, when we compare FS1.4. to FS1.3. The same is true for other Zerg matchups when looking at 1.3 -> 1.4., where the left side spawns become a bit better. There are some fluctuations, but the trend goes in the right direction.

case 2, FS top right spawn Protoss

I actually didn't know about this, so I was very glad when eon mentioned that top right spawn is known to be advantageous for protoss. These advantages in mining should be most relevant in the mirror matchups, and this is what we see.

PvP on FS1.3+ Show Spoiler +
[image loading]

PvZ on FS 1.3 + Show Spoiler +
[image loading]


Protoss spawns top right on FS = big peepee.

It looks like the change to 1.4 partially improved this in PvP, where now top left is also a good spawn. + Show Spoiler +
[image loading]
Not quite sure how to interpret this, maybe someone else can comment. Also there's stuff like, for example, in PvT on FS1.3.: where bottom right is the best spawn: + Show Spoiler +
[image loading]
and when we go to FS1.4., its much more balanced overall + Show Spoiler +
[image loading]
, except that bottom left remains worst spawn by far.

So there is plenty of very match-up specific stuff that I don't quite understand, but also more variables at play. In the mirror match-up, everything seems as expected.

case 3, 12 o'clock spawn Zerg on Dominator

This spawn is known for very quick mining for Zergs, also confirmed by the data at hand.




What now?

First, here's the rest of the data on spawn-specific stats. It's grouped by

matchup -> map

and then there are 3 plots each, one per MMR bracket. Feel free to re-upload them somewhere else to be able to repost or reference them here.

There are hundreds of plots overall, have fun browsing them. I'd recommend you look for the match-ups you play yourself and maps that you like in particular, and try to see whether you find anything interesting or noteworthy.

There might be better ways to structure this and present it, I'm looking for input there as well. Also if you have any specific sanity tests or cross-checks that could be applied to make sure everything works as intended, please comment. I should add that the results did not pass all my vibe checks. For example, on FS, the bottom left spawn is supposed to be particularly bad in TvZ, which we do not see in the data. Now, whether this is because something is wrong with the methods; or, because every Terran knows that this spawn is supposed to be worse for them, and they looked up how to best place turrets; or, this spot never was bad at all; I don't know.

Regarding what all of this means for the game, I'm not sure either. Most often, there seem to be several variables involved at the same time, with overlapping effects.

- Specific spawns seem optimal for one race, but might be not optimal at all for a different race
- Some maps have wildly imbalanced spawns, while others are pretty balanced
- Quite often, the variance between specific spots is higher than the difference in the win rates for the matchup as a whole

I didn't want to theorize too much on what the underlying causes could be, e.g. is it more of a left-side-spawn vs right-side-spawn bias, or is it about top side vs bottom side, or is it specific to horizontal vs vertical entrance only relevant in PvZ + Show Spoiler +
but it seems like vertical entrance natural expansion is MUCH better for protoss in pvz, compared to horizontal entrance. its a mostly consistent thing
, etc. etc. etc., but I invite everyone to share their findings and what they think about the data.

Anyway, thanks again to repmastered for the data, and everyone consider donating a dollar for the free services we get. The stuff you see here is based on 21 million replays and should be updated to 70 million (including the current ladder maps) in the next few days.

PS: it was noted that the 70 million games on repmastered refer to all replays there, which include team games, fastest, etc. If we consider only ladder games, we end up with ~25 million games.

The average game length for a zerg is around 12 minutes. And the peak winrate for t v z and p v z is around 12 minutes. Way above 50 %. How should we interpret that? WE ARE THE MOST MISUNDERSTOOD RACE!

So we can see that cross spawn is overall balanced, close spawn is not quite. Why not just make more 3 player maps?

It would be a slightly longer distance than close, but shorter distance than cross.

Any terran player that could explain why Polypoid bottom right is such a good spawn for you ? I think top right and bottom right what they have in common is the same mineral lines. Sim City is different. Is it by being at the right side any beneficial with defense and mobility of your army any different to the left side ?

I tried a different browser (Firefox at first, then Chrome) and none of the images work. But they work on mobile (iOS). Must be on my end then, especially when I seem to be the only one. I'll check it out on my phone then

but it seems like vertical entrance natural expansion is MUCH better for protoss in pvz, compared to horizontal entrance. its a mostly consistent thing

Hydra bust is slightly less powerful when done vertically compared to horizontally. At least that's the idea why they designed all the entrances in Radeon like that.

Bottom right on poly has ling tight wall in nat available with marines spawning inside.

There has to be more to it to justify such a high WR on this spawn.

to me it seems like usually there are several overlapping factors

there seems to be an overall left-vs-right spawn bias on 4-players maps, where its better to spawn on the right side

I think top right and bottom left what they have in common is the same mineral lines


one would think that, but the same mineral layout is not sufficient to guarantee the same mining rate. Its actually much more about pathfinding regions, which is basically a bunch of random bullshit.

Do you mean that Litmus for example has different income rate ?

Terran is doing fantastic on Litmus with such mineral setup but i think the biggest factor is the third gaz. And the lack of terrain for protoss to attack terran. And well a 2 player map where protoss cant do their favorite strat of stealing gaz from the get go i imagine play a huge role aswell. But im unsure about the last.

But polypoid for example usually terran goes for the mineral Only. Maybe since is a very easy expo to defend could be also an issue for terran that is unable to punish it. and then terran can quickly take a 4.

Yes, it can be. Even though the mineral formations are perfectly identical. It does not guarantee that workers will behave the same.

The reason are pathfinding regions, the yellow rectangles: + Show Spoiler +
[image loading]


These pathfinding regions determine which path a worker will take after it mined a patch of minerals.

You might remember how on older maps, workers used to do very weird stuff and have strange pathing. Today, they don't, because map makers spend a lot of time to make things look fluent. What map makers do is not to just place the minerals and be finished. Pathfinding regions are calculated by the game depending on the layout of walkable and unwalkable tiles by a very stupid and hard to control mechanism.

If you ever noticed "random" unwalkable tiles somewhere on the map, those were placed deliberately by the map maker to adjust the pathfinding region. On the Litmus pic above, on the right side, below the gas is a small yellow rectangle. This is an unwalkable tile that was deliberately put there by the map maker to adjust the pathfinding region around this spawn location.

But since this process of fixing pathfinding regions is both tedious and random, map makers usually stop when they were able to get rid of everything that looks bugged. This however does not guarantee that mining rates will be similar.

Maybe do the win rate vs game duration of the top right and top left populations and see if there's a higher/lower peak of top right at some minutes and have a clue of where the extra wins come from?

That is so interesting. In fact this extremely strong WR on advantageous spawn could be getting also bonuses from spawns randomizers. For example how often is poylpoid bottom right getting vs top left or bottom left compared to top right ? For example on FS i remember more often than not when i was on top right i will see the overlord coming to my base easily 4 from 10 games LOL. I could be tweakin on this tho. But i think Spawn randomizer is a big factor. Hell back when i started BW i remember me and friends could predict opponent spawn cuz The lost temple version only had white color to be on only one spawn. xD

seems like right side of the map benefits from better mining, while at the same time we have 2-zealot gaps at top right and bottom left compared to 3-zealot gaps in bottom right and top left.
As such, top right benefits the most, top left suffers the most.

Back in the early days of remastered ladder, FS positions were locked to top left vs. top right, maybe that is affecting your statistical perception of the phenomenon? Or is this something that continues to this day?

I would be really surprised if (outside of anomalies like these) there is some bias for spawn locations on modern maps. Feels like progamers would sniff those out due to the sheer volume of games they play. Still, would be a great statistic to look at to determine any deviations from the expected norm, if possible @Kraekkling.

the spawn randomizer works fine, the relevant stats are already included on the spawn-specific plots.

in the spawn-squares, look for the N = XXX number, which tells us how often players spawned there

Sorry that I missed this, but I guess the relevant question here is spawn pairs? If 50% of games are TL vs TR and the other 50% are BL vs BR, then the spawn squares would be balanced but exclude the majority of spawn interactions, just to provide an extreme example.

Interesting, first I am hearing of it and I was very active back then so I feel like I would have noticed, but I was also a full-on scrub so maybe not Hopefully Kraekkling will be able to provide us with pair-wise analysis for the spawn locations. Could be interesting to break it down by year too, if possible, to test your hypothesis.

PS: Do want to say thanks to Kraekkling for the work done on both this post and the previous one (which I remember very well!). I don't want to seem like I'm always complaining or needy without showing appreciation as well.

I believe besides the fact 3p maps are incredibly difficult to make (fitting an equilateral triangle inside a square - like NEMEC mentioned in the past), ZvZ can also become luck-based, which may not be good for tournament play.

they can bring back Apocalypse into the map pool. statistically it is the most balanced map together with Radeon. Apocalypse also produced a lot of very high quality entertaining matches.

I wasnt around when Monopoly was used in the ASL mp. But i looked at the picture of it and is surprising that protoss actually dominates zerg and terran in such map. I mean not by a huge extent. I honestly could believe such stats are actually balanced. But it is a map that never comeback.

IDK about difficult but i would say the best maps made in SC remastered are proly.Sylphid / Ascension / Apocalypse / Dominator / all of them 3 players map.It seems map makers figured out the formule to get bangers out of 3 players while the 4 players formule is right now stuck in those boring clones we are getting. With the exception of Tempest that imo should have made few changes and be put again into the MP.

I'll just quote NEMEC (he was responding to you on that thread actually, RJBTV. You were posting on that thread too, EonZerg):

3 player maps are actually harder to make than 4 player maps. Drawing an equilateral triangle inside a square makes the map feel much smaller. (It becomes even more challenging when considering air units.)

Additionally, in Zerg vs. Zerg matches, Overlord searching luck can decide the game's outcome, leading to games that rely too much on luck.

I personally think LatiAs is excellent at designing 3-player maps
(Sylphid, Apocalypse, Dominator).

When I have balance concerns while designing a map,
I often seek his advice as he has a great understanding of map balance.


I remember Freakling the great foreign mapmaker also said somewhere that 3p maps are very challenging, and it's not something all mapmakers are confident with. Testbug is one of the rare foreign mappers to be very proficient with 3p maps.

All the maps you listed are all made by LatiAs, Eonzerg, so it looks like out of all ASL-approved mapmakers, he's your best bet for a new and nice 3p map.
