Challenges are unlocked upon reaching Infinity. A challenge requires reaching infinity with special conditions. They will provide an autobuyer upon completion.


Public ID Description Details Reward Internal ID
1 Reach infinity for the first time. Automatically awarded on Infinity. First Dimension Autobuyer 1
2 Buying anything halts your production, gradually coming back over 3 minutes. Increases all dim power linearly until it gets to 100% at 3 minutes Second Dimension Autobuyer 2
3 First dimension is heavily weakened but gets an exponentially increasing bonus that resets on reset. 1st dims are 100x weaker, but increase by 1.00038^10 times per second. Third Dimension Autobuyer 3
4 Buying a dimension automatically erases all lower tier dimensions, like a sacrifice without the boost. Fourth Dimension Autobuyer 8
5 Tickspeed starts at 7%. See Ticks Fifth Dimension Autobuyer 6
6 Each dimension costs the dimension 2 before it, with modified prices Base prices: 10/100/100/500/2500/2e4/2e5/4e6

Price increases: 1000/5000/10000/12000/18000/26000/32000/42000

Sixth Dimension Autobuyer 10
7 Multiplier per 10 dimensions is random from 0.30 and 10 ((10/0.3)^r)*0.3 (r is random num 0~1), x1.1 from inf upgrade Seventh Dimension Autobuyer 9
8 Dimension Boost and galaxies are useless, sacrifice resets everything but is immensely more powerful See Dimensional Sacrifice Eighth Dimension Autobuyer 11
9 Whenever you buy 10 of a dimension or tickspeed, everything else of equal cost will increase to its next cost step. (when you buy enough of a dimension to get its power step; cost comparisons use single buy cost) Tickspeed Autobuyer 5
10 There are only 6 dimensions, with dimension boost and antimatter galaxy costs modified. See Dimension Shift and Boost and Antimatter Galaxy Dimension Boost Autobuyer 4
11 There's normal matter which rises. If it exceeds your antimatter, it will dimension boost without giving the bonus. Acts as if you pressed the "lose a reset" button. Matter increases at a (1.03 + player.resets/200 + player.galaxies/100)^10x rate per second. Galaxy Autobuyer 12
12 Each dimension produces the dimension 2 below it; first dimensions produce reduced antimatter. 2nd dimensions have ^1.7 power and ^1.5 "amount" affect on production

4th dimensions have ^1.4 power and ^1.3 "amount" affect on production

Big Crunch Autobuyer 7

Infinity Challenges

There are also Infinity Challenges, which unlock much later. They have an end point past Infinity, and provide powerful rewards.

Number Unlock Req. End Point Description Reward Details
1 1e2000 1e850 All previous challenges (except tickspeed challenge and automatic big crunch challenge) at once 1.3x on all Infinity Dimensions for each Infinity Challenge completed multiplicative reward
2 1e5000 1e10500 Automatically sacrifice every 8 ticks once you have 8th Dimension. Sacrifice autobuyer and more powerful sacrifice See Autobuyers and Dimensional Sacrifice
3 1e12000 1e5000 Tickspeed interval decrease is always at 0%, but every tickspeed purchase you get a static multiplier on all dimensions (increases with galaxies). Static multiplier on each tickspeed purchase (both) 1.05+galaxies/200 per tickspeed purchase
4 1e14000 1e13000 Only latest bought dimension production is normal, all other dimensions produce less. All normal dimension multipliers become multiplier^1.05 Penalty is ^0.25 to dim power.
5 1e18000 1e11111 When buying dimensions 1-4, everything with costs smaller or equal increases. When buying dimensions 5-8, everything with costs bigger or equal increases. When buying tickspeed, everything with the same cost increases. Galaxies are 10% more powerful and reduce the requirements for them and dimensional boosts by 1 Cost comparisons use the exponent value and ignore the mantissa.
6 1e20000 2e22222 There's an exponentially rising matter that divides the multiplier on all of your dimensions. Tickspeed affects Infinity Dimensions with reduced effect Matter rises the same way as c11, tickspeed boost is /(tickspeed/1000)^0.0005
7 1e23000 1e10000 You can't get antimatter Galaxies, but dimensional boost multiplier 2.5x -> 10x Dimensional boost multiplier 2.5x -> 4x
8 1e28000 1e27000 Your production is at 100% after purchasing anything, after that it rapidly drops down. You get a multiplier to dimensions 2-7 based on 1st and 8th dimension multipliers. Receive a 0.000000046416^10 penalty per second. This penalty is computed before production in an individual tick. The reward is (1st dim mult * 8th dim mult)^0.02.

Eternity Challenges

Like Infinity Challenges, there's Eternity Challenges which the goal is to reach amount of IPs then Eternity instead but requires different each and cost Time Theorems. For the first five times you complete each challenge, the requirement and goal rises up and the reward will be more powerful.

There is a bug that let you start 6th time, but however when you completed it, nothing would be rewarded and challenge completed amount will be the same.

n in the reward and requirement is the amount of times completed, up to 5.

You will receive the reward for clearing upon first clear.

6 40+5n replicanti galaxies 85 1e850 1e250 You can't gain galaxies normally, but the cost of upgrading your max replicanti galaxies is massively reduced. Further reduction dimension cost multiplier increase, Currently: ()x 3-0.2n
