World Size and Seed Collection Thread

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

Hello, everyone! I have wondered if there was a limit to the size of a world. Thus, I began a phase of playing Thrive to find different World Seeds.

For me, I want to have worlds that are diverse and have every biome/patch type in the game. This way, I can theoretically have more interesting organisms.

I also want to find the largest and smallest possible world sizes and their corresponding seeds. Large worlds can host more organisms, and theoretically have more interesting organisms, as aforementioned in the previous paragraph. Smaller worlds are important for quicker gameplay and less taxing on computer systems. Considering my current computer is almost 10 years old at this point, this is very pertinent.

I also noticed that there is no current Thrive Game World Seed Collection post on the Forum, where people can post and share interesting world seeds. So, I wish to add something to community.

First off, let me put the best parts of my search: the largest and smallest world seeds I have found so far. Keep in mind that are probably larger and smaller worlds than what I will post. Also, the current game version as I am posting is 0.6.7.1. Additionally, since I am still new, I can only add one picture.

The 46-patch World Seed: 6165598193527994777.

The 13-patch World Seed: 7681595076449933380.

Next, I would like to share the first seed I got using the Auto-Evo tool. I have also added the statistics that I am using to determine whether or not something is diverse. I aware of diversity indexes, like Sampson’s Index of Diversity (SID), but I have not yet analyzed all of the seeds I collected.

Statistics:
Seed Number: 98063184769791023
Number of Patches: 28, Number of Patch Types: 11
Frequency of each Patch Type: Cv=4/28,Cl=4/28,TP=2/28,Es=1/28,IS=1/28,EP=3/28,MP=3/28,BP=2/28,AP=1/28,SF=4/28,VV=3/28
Number of Land Patches: 8, Number of Sea Patches: 20
Number of Surface Sea Patches: 3, Number of Surface Land Patches: 7

Average Number of Patches per Land Patch Group: 2
Maximum Number of Patches in a Land Patch Group: 3
Minimum Number of Patches in a Land Patch Group: 1
Mode/Median Number of Patches per Land Patch Group: 2

I look forward to seeing what other World Seeds everyone else finds!

Note: Make sure to add the game version number in case World Generation changes again in another update!

Note: The World Seeds still work in 0.7.1.0.

Note: These Worlds Seeds do not work below 0.8.1.0.

I found a 47-patch World today (Jan 2, 2025)! Version 0.8.0.0.
47-patch World Seed: 6938878236475470788.

I found a 46-patch world with six Underwater Vents! This is the most Underwater Vents I have found for a world this large! (January 5th, 2025) (Version 0.8.0.0)

46-patch-with-six-vents World Seed: 1524739792460623285.

I also found another 47-patch world! This one has more Tidal, Coastal, and Estuary patches, in case people want another large world that has more diversity. (January 5th, 2025) (Verson 0.8.0.0)

47-patch-with-more-Tidal-Coastal-and-Estuary World Seed: 4119097735072505814.

I finally found a world with over 50-patches! A 52-patch world! And it has six Underwater Vents! (January 10th, 2025) (Version 0.8.0.0)
52-patch-with-six-vents World Seed: 6719440032949089259.

0.8.1.0 World Seeds

The first 14-patch world seed I found for 0.8.1.0 had one patch group with Mesopelagic and no Ice Shelves.
0.8.1.0-14-patch-Mesopelagic-No-Ice-Shelves World Seed: 2424298567572378553

I was able to find a 13-patch world seed for 0.8.1.0. that has an Ice Shelf, Mesopelagic, and a Volcanic Vent eruption on the first turn!
0.8.1.0-13-patch-Ice-Shelf-Mesopelagic-Vent-Eruption World Seed: 740553269396837828

I found more seeds!

I was able to find 12 and 11 patch world seeds!

0.8.1.1-12-patch world seed: 2286272470713257455 (4/25/2025, 9:18 P.M).

0.8.1.1-11-patch world seed: 3546547847789981185 (4/25/2025, 9:26 P.M.)

And a 41-patch world seed!

0.8.1.1-41-patch world seed: 470527404734541274 (4/25/2025, 10:16 P.M.)

0.8.2.1 World Seeds

I found several World Seeds with Banana Biomes! Banana biomes are very rare; about 1 to 2% chance to spawn.

Note: 0.8.2.0/0.8.2.1 seeds have Banana Biomes in all three world sizes. Since the features change with each World Size, I have only included the Medium-sized World Patch Number in the descriptions.

0.8.3.0 World Seeds

Note: For 0.8.3.0, there are now world customization options which also affect: 1) the number of ice patches, via Temperature; 2) the number of land (continental) and sea patch groups, via Ocean Size; 3) the frequency and magnitude of vent eruptions and meteor impacts, via Geological Activity; and 4) the frequency and magnitude of global glaciation, via Climate Instability.

For simplicity purposes, I will be using the medium world size and the Intermediates FG seed as examples: 7681595076449933380. All world maps were found on 8/21/2025.

Mediums-sized Worlds

Has Temperate Temperature, Medium Ocean Size, Average Geological Activity, and Average Climate.

Has Warm Temperature, Large Ocean Size, Active Geological Activity, and Unstable Climate.

Has Cold Temperature, Small Ocean Size, Dormant Geological Activity, and Stable Climate.

That’s a lot of vents right there…

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

Crazy thing is that this might not even be world with the most vents! I am still trying to find worlds that have 50 patches and above.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

What is the smallest world you found?

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

This is the smallest world I have found so far.

@AnthropocenianAge

The 13-patch World Seed: 7681595076449933380.

Theoretically, in the current game, it is possible to have all known patches within a 12-patch world. I am still trying to find a twelve patch world.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

I guess somebody could code a tool in the future to make seed checking faster…

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

I wish there was a tool just to find world seeds. I do wonder if that is something the developers are planning add eventually.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Probably not anytime soon…

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Btw, you could edit your first three posts in this thread into one, so that you don’t have a triplepost on your record, which is a grave crime in this forum.

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

I keep forgetting that I can keep editing my posts; plus, I am not sure how many times I can edit a post.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

@AnthropocenianAge

I am not sure how many times I can edit a post.

Enough to merge 3 posts into one.

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

Thanks for the help!

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

The note of the seeds still working in 0.7.1 could too be merged into the 1st post.

[hhyyrylainen]

I don’t think there’s a limit…

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Yeah, exactly

I can guess that patchmaps will have less size variations once planet generation is tied into patchmap generation.

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

I wonder how different worlds will be after 0.8.2.0(+)? I hope for interesting worlds.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Not sure much changed in the actual patch generation. More events are now around I suppose.

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

Worlds with Banana Biomes are rare, right?

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

I think so, it’s an easter egg after all.

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

I am trying to remember, is it around 10% chance for a World to have a Banana Biome?
