This guide covers first eternity, milestones, animals (zoo), laboratory, and eternity challanges.
Revolution Idle: Eternity Guide
First Eternity: Each Eternity provides passive Eternity Bonuses which are permanent and can be viewed in the Eternity Milestones tab. Eternity Points will be used to buy Laboratory and Animal Points when they become available a little later.
The bad news with your first Eternity is that everything else gets reset and you will need to go through it all again for your next Eternity. However, with the Eternity Bonus and all your achievements it will be faster (although it will still feel slow). You can now see Eternity Milestones and how many Eternities are needed for each perk or additional feature. For now you need…
Eternity Milestones #1-2: Self explanatory
Eternity Milestone #3: Unlocks Eternity Zoo
Animals: Each animal provides a bonus and is bought with Animal Points (AP). Animal Points can be purchased with Eternity Points, current run Score, or current run IP. There is also an Animal Milestones sub-tab.
Note: When Infinity or Eternity resets, so does your current Score and IP, meaning you need to buy AP when they are available before reset. To get higher Score/IP you will need to break Eternity with Milestone #10.
Animal Milestone #1: unlocks slowdown.
Slowdown: Basically reduces lap speed in exchange for an Ascension. Can only be used when all colors are solid. When you first get it, you need to be careful not to slow down too much. If you use the slowdown too much and prestige or a promotion resets colors, the slowdown remains in effect, which can be a real drag. You can “speedup” again, but it’s better just to not overuse it. Having said that, it is very much worth using when you get into the longer IP runs.
With a couple animals, Eternities should be going much faster now. You won’t be able to do too much more with animals for now, so the next goal is to keep unlocking Eternity Milestones, but keep buying AP when you can.
Eternity Milestone #4: Buying colors (revolutions) now costs nothing. Nice!
Eternity Milestone #5: Unlocks Auto IP Adjuster
Auto IP Adjuster: When IP is claimed (either manually or by using Auto Infinity value), the adjuster multiplies your Auto Infinity value by the Auto IP Adjuster value increasing the Auto Infinity value so you don’t have to. You then only really need to buy upgrades and generators.
Example: Automate Infinity value 1e110 x Auto IP Adjuster 1e10 = 1e120 New Auto Infinity Value
(The number after the “e” is how many places are after the first number, so 1000 = 1e3)
Eternity Milestone #6: Unlocks Eternity Challenges
Each challenge provides an immediate bonus when completed. In addition, there are also Challenge Milestones for completing a combined total number of any challenges. Each challenge also has 5 levels of difficulty. Each difficulty provides completion bonus and adds to the Challenge Milestone count. Unlike Infinity Challenges, once completed there is no reason to run a challenge again (you only get the bonus once). Completion time does not matter.
You do not need to complete challenges when they first become available. In many instances it would take far longer than you would want. If a challenge is going to take longer than 30 mins, in most cases there are better things to do with that amount of time.
Animal Milestone #2: Unlocks Auto Slowdown. Nice you don’t need to do it manually anymore, but with auto active, it can definitely slow you down too much. I do not understand the math of it, but for now, if you set it to 1000, it should be about right for gains vs. speed loss.
Eternity Milestones #’s 7-9: Unlocks Auto Eternity (set it to 1), Auto buy Infinity upgrades, stars/stardust, generators (turn them all On with Generators to Max buy setting).
Eternity Milestone #10: Breaks Eternity
When you can break Eternity, you can get a few more Animal Points with Score and IP, but not a whole lot yet. Once you buy the AP that you can with broken Eternity, I recommend just auto Eternate at 1 Min EP for now.
When you have 11-13 AP, buy or respec to animals 1:1-2, 2:1-4 (If you have enough AP to buy 2:5 even better) for focus on lap speed and go into the Eternity Challenges and complete Challenge #1, difficulties 1-3 for the first Challenge Milestone.

These will be slow in the beginning but after the 1st Infinity will be very doable. Before your next eternate, get you Infinity challenges as low as they will go since Challenge Milestone #1 allows you to keep the best times.
Eternity Laboratory and Zoo
At this point buy or respec animals so that you have at least 7 total for the next Animal Milestone.
Animal Milestone #3: Unlocks Laboratory
Spend EP to generate Lab points which fill the beaker. Each time the beaker fills you get 1 Research Point (RP) to upgrade 1 of 6 bonuses. Currently there are only 4 that are worth the investment:
#1 IP Gain, #4 EP Gain, #5 Gen power Exponent, #6 Common Exponent.
Right now, you don’t have enough power to get very far into Broken Eternity which means your EP gains are probably maxed at maybe 3 or 4 per run (as you noticed, you need a lot more than that). You need to kickstart the Lab to get more EP. I highly recommend your first 6 RP be spent on #4 EP Gain, and then into #1 IP Gain so that #1 is about x2 more (a 2:1 ratio up to 16 pts in EP after that all in IP). This ratio can change with less in EP.
Note: The above is what I used. Some people say that all in IP is always better, so find what works for you.
I also highly recommend turning off Auto Eternity since it can fluctuate a lot (I’ve had anywhere from 30-118 EP with the same settings). When progress comes to a halt, just claim EP.
If you do want to use Auto Eternity, make sure it’s a low enough value that you know you can hit and not get stuck grinding and about a 10-15 second timer so that it can go beyond that point as well. Still a good idea to re-evaluate it after buying lab upgrades.
Before long you should be able to buy 10 total animals I went with 1:1-5, and 2:1-5 but that’s up to you.

Animal Milestone #4: Promotions reset nothing. Nice!
Go into your automations and set all your promotions to +1 and 0 sec and watch it go nuts.
Challenge Checkpoint: Now would be a good time to finish Challenge #1 for the next Challenge Milestone. Respec your lab to a 1:4 ratio into upgrades #5 and #6. The ratio does change so check it. For me the 1:4 ratio worked all the way into Dilation but there can be a lot of variables so find what is best for you.
Note: To quickly find the best ratio for the lab, Set a target amount in Auto Eternity that would take approximately 1-3 mins. When it reaches the goal, switch the ratio to what you want to check and compare EP/s. This works better after you have Animal Milestone #5.
Challenge Milestone #2: Prestige resets nothing. Excellent!
Now you can set your Prestige mutiplier however low you want (I use x2, but that’s up to you).
You should also be able to do Challenge #2 x2 and Challenge #3 x1
Challenge Milestone #3: Unlocks Supernova. Go Supernova when possible for more boosts.
Note: This is the last time I call out challenges, do them when you want just remember they are not worth spending long periods of time on. It’s more important to keep the other things progressing and the Challenges will finish in seconds or minutes when you’re able to.
Now that Prestige and Promotions reset nothing, you can also change Auto Slowdown setting. After some testing, 10 seems to be the best for me. Others disagree so feel free to experiment.
For now keep working on the Lab and Animals. Occasionally switch between the IP/EP lab setup (for gaining EP), and Gen power/Common Exponent setup at a ratio of 1:4 (for score to buy AP and Supernova). Again, verify that that is a good ratio for you.
Turn ON auto Eternity for IP/EP setup to probably between 3-10 secs (you can leave value at 1).
Turn OFF auto Eternity when doing Score/supernova runs.
*Note: You can respec your animals to focus more on IP/EP or Score/SN. I found this to be too tedious and just left them as described and didn’t respec at all.
Animals to get: Right now the goal is 20 Animals for the next milestone. I recommend them to be the whole block 1:1-5 through 4:1-5 You can get them in any order but IP and EP boosters should be priority. These 20 will be your base to keep the Milestone Active, all others build from these.
In the Diagram:
- Yellow is the base animals (keep these)
- Red is to boost IP/EP gains
- Green is to boost Score/Supernova
- After you have all of those, fill in the rest as you choose (I just buy the cheapest).

Next Animals goal: 5:2 (Frog) then 6:2-9 (Giraffe down through Pegasus) to boost IP.
You should be able to get a Supernova about every 10-20 Lab Research points. Remember to turn off auto Eternity and switch lab focus to 1:4 ratio between #5 Generator: #6 Common or what works best for you, and also check to see if any Challenges can be quickly finished. Buy Score AP before switching back to IP/EP setup.
After you have Animals 6:2-9, I recommend the cheapest which would be 1-4:6 and 1-4:7. These are for boosting Score/Supernova.
Checkpoint: You should now have Supernova 20 or 21, Laboratory about lvl 410, and 28 or 29 challenges completed.
At this point your Score/Supernova Lab setup should be getting about the same results for EP gains as the IP/EP setup and you should now be able to do longer runs with better results. If not it will before long so look for it. When It does, either set a target value for EP or claim it when you want. You want a balance between gaining EP and keeping the lab growing. Keep upgrading the lab, buying Animals, getting Supernovas and occasionally checking in on Challenges.
From this point forward, Lab points should always be in #5 and #6. The only thing that changes is the ratio. For now 1:4 seemed to be the best for me. I highly encourage you to find what works best for you since there are many variables.
Animal Milestone #6: +10 free levels to all RP upgrades (a very nice boost).
Challenge Milestone #6: More free Research upgrades.
Finishing Animals will go much faster now.
Note: For Eternity Challenge #9 put all lab points into #6, since generators are useless.
Challenge Milestone #7: More free Research upgrades. Challenge Milestones complete!
Animal Milestone #7: Unlocks Dilation. Animal Milestones Complete!
