In the realm of Tentacles Thrive, you will be discovering new tentacle species, stealing Lilith's heart, mating to create new species, managing and reviving the Humana race, or conquering the world through strategic battles. It is an SLG game with a love sim element and real-time battles.

Join us if you enjoy our craft!

Here are some unique features:

  • 136+ species (currently 50+ species, including enemies)
  • Unique story events and hand crafted mating scenes for all Tentacles species!
  • Real-time strategic battle with simple card game like element
  • Every monster, ally or enemy, possesses an unique effect to add in chaos on the battlefield
  • Have a chance to enslave the enemies after a successful conquer, which can be used in the future battles (undeveloped)


Living in a world filled with large and powerful monsters, the Humana Kingdom has been confined on a small island for as long as anyone can remember. One day a royal family member, Lilith, discovered that the materials she had been collecting to create fabulous clothing, were derived from creatures called Tentacle Monsters. This discovery, though seemingly benign, would became the event that shook the very foundations of the world and forever change the dynamic between Tentacles, the Humana Kingdom and all the other nations of TT.

Backgrounds of Lilith, Tentacles, and Humana Kingdom

Lilith - most of Lilith's family was killed in an invasion by monsters. Being born into a wealthy family, she was later adopted by the royals. She is most famous for creating beautiful clothing with a secretive fabric (dead skin from tentacle monsters). Little did she know that eventually the tentacles would mistake her as one of their own, and ultimately treat her as their queen.

Tentacles - rare creatures that live in some of the worlds darkest places. They are incredibly adaptable, shifting willingly from being solitary creatures to eusociality after their first meeting with Lilith, thus treating her as their queen. This co-evolution will bring great benefits to both the Humana Kingdom and Tentacles, but only if certain conditions are continued to be met.

Humana Kingdom - possesses basic understanding of agriculture and melee weapons, but lack the time to further develop important technologies due to constant threats from other monster nations. They rely on their geographical advantage to defend themselves. Indeed if they did not have it they would have been completely destroyed long ago. Thus, are they in a war of attrition.

This looks good, but it's so sad that it's flash

how do you make a tentacle injured? I can't progress the instinct unless I can nurse something, which you cant do if they aren't injured.

I know hunting says they have a chance to be injured but it hasn't worked, even after sending out tentacles with low camouflage and senses to hunt many times.

(1 edit)

Hmm, hunting with the same monster many times should get it done. Monsters will get injured once their stamina is used up. 
If it doesn't work, it could be a bug. Let me know in that case.

Hi everyone
Where is the Tentacles Thrive v4 06 Savegame Folder?

Now anyone where i can find the the savegame folder?
The location on the pc.
I have a few problems : when I try to save the game Tentacles Thrive v4 06 " the game doesn't save them " :(

Try our fan made wiki and see if it helps: https://unofficial-tentacles-thrive.fandom.com/wiki/Q%26A


is there a cheat for unlimited turns


what is that ?


Why do downloads always fail?

(1 edit) (+1)

probably your computer cant handle them or you have something interfering with them, some apps can do that. and theres aways the possibility you have a virus. or maybe your computer is just too old and you need a new 1.

Hi! First, you made a great game, thank you for that!

I get some bug, after attack and win Highburn, i got title on screen "Commoner (Coming soon)", and nothing more can do. Version - public 4.06.

here screenshot, and save (before attack), if you need one:



p.s. sorry, english is not my native language

(2 edits)

Many thanks vapp1asur! It is a confirmed bug. It was fixed in the newer version.

Oh, i understand, thank you!

for some reason i get this bug no matter what territory i take (version 4_06) :O






when will 4.06 be out. And where did Master go he disapired?

Its out :P

When will you release the next update atleast gove us a hint about upcoming update

I usually release them every month. 

Is the game supposed to open on a Flash Projector window?

Also, I can't save the game; it says that the game is saved, but no save file is created and when I reopen the game the Load button does nothing.

Great game, btw. Really enjoyed it.

Managed to fix the saving issue; I put the game in a folder on my Desktop, and now the save function works. No idea why it didn't before, though.

I tested the smartphone version.
This game is excellent.
However on Android we are limited.
We can't create tentacle clothes, we don't have access to all instincts, we don't have access to secret endings.
If anyone knows the latest version on android, I am interested because my computer is in repair at the moment.

What "smartphone version" are you talking about? There is no such thing here, you might have played someone else's android port.

I went to the wiki and saw that the feeding system is "in the future"?

So I can only feed my Dubious' sexual hunger not his actual hunger?

Hehe, well you can use items, including food through Bonding now.


Nigga you telling me that my characters pussy is now food?

I really enjoyed this game. And can you add a feature that we change dress of Lilith and select another dress or make her naked in the game because she is always wearing the same dress which I found a little boaring and also can u add some more scenes and also an option to disable audio within the game and also make the saved data compatable with the upcoming version. Overall I loved the game and also improve some graphics and bugs. After sometime i will surely donate money for your work 

Thank you for the kind words mate. Saves work for downloaded versions. Web version wise, the save is there but as I have answered before, it takes a bit of work to get it to work.

how to get it work, can I do that in my pc

List of bugs/performance issues encountered in last patch:

-Repeating some scenes through bonding will cause game to get stuck by popping a "clickable dialog lilith" but not allowing the scene to actually happen

-Repeating some scenes through bonding will cause game to get stuck for about 10 seconds, then will continue normaly. Every monster without a storyline after third bonding will have this problem as well

-Skin disapears from inventory after game restart if placed in the item to craft and save the game

-Oysters can be used but this will not consume the oyster

-Not sure if intended but some species show happy mood yet if you bond with them they will get tired

-Sometimes when you free just 2 monsters in a turf bottom panel buttons disapear, can be fixed by opening the species booklet. Doesn't happen with 1, 3 or 4

Comments, ideas, recomendations, doubts

-100% sure women dont have a prostate (sexual dimorphism) so it fees weird to read some of the scenes. Yes they are 70% of what makes the game immersive, therefore more enjoyable

-Maybe add a skip button for secret memories replay?

-Maybe add a note to which items are useless in the current patch

-Myrmidon's last choice feels inverted between hi and low rewards

-Maybe include scenes unocked through in the queens nest, might help to keep attention raised and using the nest more apealing whe it is used just to grind for a monster unlock

-Fluid animations, competent writing, enjoyable mechanics, overall great work. Congratullations, keep the awesome work!!!

Wow, thank you so much IIebocat! Best tester ever~

And thank you for trying the game ^O^

 Just doing what I can to help the project. Since it is complicated for me to contribute directly with cash because #thirdworldcountry I'll do my best to contribute in other ways. Besides, I am having a lot of fun with the game :)

(1 edit)

Awww, you are too kind!

I have a Mac, so I cannot use the download version of the game (as far as I can tell; I downloaded both files, but I couldn't manage to play them).  I have only been playing online.

Since the game updated from v3 to v4, my saved file no longer works; it seems that online files only work with the version they were made with, meaning that (if I'm correct) my current online file will stop working when the game is updated from v4 to v5.


My question is this:

Is there a way for Macs to run this game from the downloaded files, and/or is there a known release date for the v5? 

I don't ask this to pressure MasterNono (the progress has been amazing) but to find out when the "deadline" is for my online file, if that "deadline" is known.

I appreciate you trying the game. Unfortunately I don't have the equipment nor time to address all potential problems for all platforms, so my focus is gonna be on Windows only.

As for web version, we can actually reuse the save, but it is a bit complicated. This is an location on Windows:

itch save location (Firefox):
C:\Users\[user account name]\AppData\Roaming\Macromedia\Flash Player\#SharedObjects\[RANDOM
LETTERS]\commondatastorage.googleapis.com\itchio\upload2\game\[RANDOM LETTERS]

We have to copy and paste the save into new version's folder in order to reuse it. I think this is too complicated for most players so I don't broadly advertise it. But it is possible.

I really enjoy this game and look forward to future updates.  The two problems I'm having right now is saving, and figuring out how to encounter other tentacles.  I mean, I can explore different regions, but I can only seem to encounter 1 tentacle per certain regions, and then none in other regions.  I really want to get a Cirrus, but am having problems encountering one.  I also don't understand how the breeding with multiple tentacles to get a new one works.  There is no option for that when I play, and I do not know how to get those options.  I think there needs to be more of a tutorial about how to do this, or some more detail written into the fan wiki in order for users who are having problems to understand.

If it wasn't for those two things, I would have no problems playing this game all day long.  I just don't have the patience to figure out what I don't understand and can't do.  Keep up the good work though!  I still want to see what future updates are.

Thank you for playing the game^^

There are question marks on each feature once you click in, which offer tips on how they work.

I will think about how to further simplify things...


Great game, but I seem to be having trouble saving progress. I can get to the save screen fine, I click the save button and (after a popup depending on what format I'm using) it confirms that I've saved my game. Then, if I go back to the main menu and press load, the button does nothing.

I've tried a range of fixes, but the problem persists across chrome (incog and normal mode), .exe file (administrator and normal), and .swf (administrator and normal.) Anyone else having this issue?

What version of game are you playing? 

(1 edit)

The latest download, 4.05 . If I recall, the previous versions didn't give me any trouble with the saves, it's something about the newest patch. The issue also persists through reinstalls.

Did some more digging: the download have the same problem on another computer, but on the desktop regular chrome works.


this is so great, adore your work please continue.

great art and cg too yaay, i just hope it will be available for macs after the flash is gone cuz it's nearly futile to download as it doesn't open or unzip...

(1 edit)

Please can you make eyes in skill menu bigger/more noticeable, because I have Xiaomi Redmi 7 A, and eye and zone where it activates by a finger tap is too little, so it's not only hard to noice this In the beginning, but it's hard to access to. At least it's my experience, maybe it's only on my shitty phone. 

I have to say the game only supports mainly windows...

Oh, then it must've been a portable version created by fans. My apologies. Just notice this, when game will be officially ported.

where can i find the save file?

Local save location:

First narrow down the scope by going to this directory. **(See how to unhid AppData folder if you have it hidden: https://cybertext.wordpress.com/2012/05/29/cant-see-the-appdata-folder/)
C:\Users\[Your User Name]\AppData\Roaming\Macromedia\Flash Player\#SharedObjects\[Random Number]\localhost

Though you don't have to find the save file. Visit our fan made wiki on How do I reuse my save file?


How do you transfer save files in exe from 4.04 to 4.05

nvm i missed a step, the wiki page is a life saver

Why there is no birth animation?

This is one of the best games Tentacles Thrive around here and one of my favorites.

chido xD

why is there no sound in new mating scenes 

Our VA Milky was sick last month, so there was no recording. The voice work are implemented in the new version(v4.06).

Hope she gets better <3

(1 edit)

Thank you for your kind word~ She has gotten better.

That's good to know. Glad she's okay.

Anyone figure out how to save using the download flash file? 


Is it possible to download a save-file to my computer directly from the online version of the game? 

I have a mac, so I cannot open the download version of the game (.swf files are Windows-only), and online saves do not always work, which is why I ask.

Thank you very much for any reply!

when will v4.05 be out i cant wait longer



I'm waiting for  steam           Tentacles Thrive 


what happened to the queens nest, twas the best way to mix species and get new ones... was also pretty amusing to watch... PLEASE RE-ADD IT

(1 edit)

Queen's Nest is designed to be Slime Eye's benefit. You have to get one to Lv14 to unlock it.

oki, thank you

keep up the amazing work

omg thank you so much i have been trying so hard trying to re-unlock it

If anyone wants to play this game on android check it out on pornoapk.com they have converted it for android

How to play this on android??

The game is not yet available for android version

(1 edit)

Yaya. Some people play it with Puffin, but I have not officially tested it.

Download from pornoapk.com

But u can't save if u use the apk unless uve found a way then Id love to hear it :D

I can't figure out how to feed my tentacles. Like half of them are hungry, but I don't know how to feed them.

Bonding > Use items

In which version the new enemy territory will open

The game is great so far but i can't seem to find a way to fight. Is the battle gameplay just a concept or already in the game ?

Thank you for trying it out~ To battle, you need to unlock Invade skillset first through Instinct (top right corner) > then click the eye icon > enemy territory > invade.

Thanks for the tip! Keep up the good work!

I can not understand why food does nothing, hearts do nothing, scales, ore, gold, train, release, crafting does nothing as well as  most of special items, map areas and instinct.

The idea, graphics and atmosphere of the game are really great, but it is like 30% complete and how many years will it take to release at least basic functions?

And sorry if this question is dumb but what tier is better, 1 or 5?

They will do things, right now since not all features are implemented, I have to disable some of their purposes. Tier is mainly to indicate stronger battle effects.

We are around at 65%. I aim to complete the game this year.

Could you make an android version?


Possible, but can't confirm.


" Tentacles Thrive, "

My Rating of is: 

  Nice Graphics
  Active Play
  Nice Scenes
  The Graphics are nice


Hehe thanks. Only pros XD

how long will it take for v4.05

I would say another 2~3 weeks.

My critique: i love the concept. But what takes me out of the game is when the text description does not match the looped animation. Possible to put pictures in lieu of animation to match the text? Followed by the best moments And climax being an animated loop. 

Thank you for playing the game and your suggestion. We try to optimize our limited resources to create the best atmosphere; on the other hand, considering the genre, we have too many species to cover for even something that sounds simple.

I'd kind of like a patch that just changes the Princess into a Prince... or well starts us off as a dude. I mean something simple... a new sprite of a handsome dude getting pounded plus some quick avatars/pics of him. That's my thing.

The text is there mainly to help increase my skill in reading.

having issues launching it on macOS

¿Cómo le hago para desbloquear las otras regiones o entrar en batalla?
