Each achievement has conditions that must be met before they are earned. Some are very simple, and some are significantly trickier. You may have to Big Crunch or start a challenge before attempting some of the harder ones.

You will receive a x1.5 multiplier to all dimensions for each completed row of normal achievements. In addition, some achievements have their own rewards.

It can be gotten early by minimizing IP, then buying only enough of each dimension to exceed the previous, then sacrificing.

Buy 0 IDs, IP multiplier must be at 10 IP price (in the infinity tab). The Eternity Milestone for 7 eternities only completes the ICs when they're unlocked. This saves about one tick per eternity.

  2. This achievement is internally called "Minute of infinity", because the achievement was originally for 1e60 infinity power. It was far too easy, and 260/60 is 4.3333.
  3. This is internally referred to as "This achievement doesn't exist II". The displayed name is a Finnish translation.

Secret Achievements Edit

Secret achievements are secret. There are currently 24 of them in the game. The name is visible before unlocking them, but there are no other hints. Once obtained, they have a picture of Nicolas/Nicholas Cage and an actual description.

They do not have a reward, not applying to the achievement multiplier. These achievements are for you to intentionally complete, and are supposed to be secret. There are spoilers for the achievements below this page (it depends on you if you want to spoil it).

SPOILER WARNING: SECRET ACHIEVEMENT LIST Edit

ID Name Description Obtaining (if different) Strategy Explanation
11 The first one's always free. Click on this achievement.
12 Just in case. Save 100 times without refreshing. ...manually. To save 100 times quickly, click the save button and then hold enter. When paranoid about losing progress, you might save really frequently.
13 It pays to have respect. Pay respects. Press F. Pressing F will make a message saying "Paying respects" at the top right of the screen.

In Call of Duty: Advanced Warfare, there's a quick-time event requiring you to press F to pay respects.

14 So do I. Say something naughty. Import "IEATASS" (no quotes) as a savefile; spaces/capitalization allowed.[1] In the Antimatter Dimensions Discord server, one of the Nadeko bot response trades is "I eat ass" leading to "So do I!"
15 Do a barrel roll! Do a barrel roll. Import "DOABARRELROLL" (no quotes) as a savefile; spaces/capitalization allowed.[1] Importing "Do a barrel roll" will make the game screen do one clockwise revolution. This is repeatable.

At one point in Star Fox 64, Peppy tells you to "do a barrel roll!". Searching "do a barrel roll" into Google will make it do a 360 degree clockwise turn.

16 Do you enjoy pain? Use standard, cancer, or bracket notation for 10 minutes with more than 1 eternity without refreshing. You only need 1 eternity before the counter will begin. Those three notations are the most difficult to use, with standard having large numbers, cancer having a possible confusing number with emojis, and brackets are confusing altogether.
17 30 Lives. Input the Konami Code. Press up, up, down, down, left, right, left, right, b, a on your keyboard in a single session in that order with no other key presses in between. In Contra, entering this code (the one here, then START) grants 30 additional lives.
18 Do you feel lucky? Well do ya punk? You have a 1/100,000 chance of getting this achievement every second. Only checks while online
21 Go study in real life instead. Purchase the secret time study. The study is an invisible study to the right of study 11. It costs 0 TT and has no pre-requisites.
22 Cancer = Spread. Buy one million Galaxies in total while using cancer notation.
23 Stop right there criminal scum! Open the console. Press F12, ctrl+shift+c, ctrl+shift+i, or ctrl+shift+j. In most browsers, those key combinations open the developer console.
24 Real news. Click on the news ticker that tells you to click on it. The news ticker you need to click is "Click this to unlock a secret achievement." which may come at random. You can speed up the process by clicking the "hide/show the news' in the Options repeatedly until you get the news ticker. This achievement was created to reward people who actually read the news.
25 Shhh... It's a secret. Discover a secret theme. The words you can import as a save file are (no quotes): "Cancer", "Christmas", "Finland", "Confused".
26 You're a failure. Fail eternity challenges 10 times without refreshing. What are you doing with your life... See You're a mistake
27 It's not called Matter Dimensions is it? Get Infinite matter. This is most easily done in Infinity Challenge 6. Matter will begin to build up upon buying a second dimension. Even if you complete the challenge, matter will continue rising. This takes possibly a few minutes to 10-20 minutes, depending on when you started IC6.
28 Nice. Don't act like you don't know what you did. Enter 69 in any of the autobuyer textboxes. "Nice." is commonly posted on anything with 69 in it, regardless of context.

Saying "Nice" after 69 likely originates from an episode of South Park called "Miss Teacher Bangs a Boy" in which the cops respond to claims that a female teacher is having sex with a male toddler with "Nice."

31 You should download some more RAM. Set your update rate to 200ms. The setting can be found in options. When you don't have much RAM, games tend to lag more. This lag effect is reduced by setting a lower frame rate.
32 Less than or equal to 0.001. Get a fastest infinity or eternity time of less than or equal to 0.001 seconds. The infinity time requirement can be easily done in Eternity Challenge 12.
33 A sound financial decision. Click on the donate link. The link is found at the bottom, between "How to play" and "Changelog".
34 You do know how these work, right? Respec with an empty study tree. Dilation upgrades, and the secret study, don't count as studies.
35 Should we tell them about buy max... Buy single tickspeed 1,000,000 times. Autobuyers work.

This is a "total" requirement - it can be spread across as many eternities and sessions as needed.

This achievement takes about 14 hours with a maxed tickspeed autobuyer and no manual work. "Buy max" is the option used to buy all affordable tickspeed upgrades in one click.
36 While you were away... Nothing happened. Have nothing happen while you were away. Get the popup that says "While you were away...

Nothing happened."

The popup only appears when offline for over 1000 seconds (16:40). To disable TD production (after eternity), enter EC1. This achievement may also be achieved by just importing, although it may not work.
37 You followed the instructions. Follow instructions. Import "tree" (no quotes) as a study tree. The button says "Import tree"; importing "tree" is doing what it tells you to do.
38 Professional bodybuilder. Get all your dimension bulk buyers to 1e100. To quickly upgrade, click the bulk upgrade button once and hold enter.
  1. 1.0 1.1 The game converts your imported save file into allcaps and removes all whitespace, then puts it through a sha512_256 (a common hash - info about it can be found elsewhere) hash, meaning that there are other things that can also be imported. However, the ones provided in the cell are the ones intended to be imported by the developers.

There was one removed secret achievement:

Dip the Antimatter - Dip the antimatter. Gotten by lowering the window size. Reference to Cookie Clicker's Cookie dunker achievement. Removed because it doesn't work on Kongregate. Previously in the spot of 36.
