Challenges

Challenges are unlocked upon reaching Infinity. A challenge requires reaching Infinity Antimatter with special conditions, which change the gameplay. They will provide a unique Autobuyer upon completion. On mobile, you don't have to complete challenges to get the dimension and tickspeed autobuyers and instead need a certain amount of antimatter to unlock them. However, you need to complete challenges to be able to upgrade the interval.

Buying Antimatter Dimensions or Tickspeed upgrades halts production of all Antimatter Dimensions. Production gradually returns to normal over 3 minutes.
When you buy anything, production for Dimensions (not their multipliers) will be reset to 0%, increasing back to 100% linearly over the course of 3 minutes (+0.555...%/s).Second Dimension Autobuyer

The 1st Antimatter Dimension is heavily weakened, but gets an uncapped exponentially increasing multiplier. This multiplier resets after Dimension Boosts and Antimatter Galaxies.
First Dimension's production is 1% of its original, but is multiplied by 1.0038065 per second. This exponential time multiplier makes a certain Achievement possible with only 1 Infinity.
(It will take around 20 minutes for production to return to normal levels.)

Buying an Antimatter Dimension automatically erases all lower tier Antimatter Dimensions, like a sacrifice without the boost.
Straightforward Challenge, buy Dimensions as soon as you can. Offline progression is less effective.Fourth Dimension Autobuyer

Tickspeed starts at 7%.
(Web) The Tickspeed purchase multiplier starts at ×1.080 instead of ×1.125.

Upgrading each Antimatter Dimension costs the Antimatter Dimension 2 tiers below it instead of antimatter. Antimatter Dimension prices are modified.
Dimension 3 will cost Dimension 1s, 4 will cost 2, etc. Base prices:10/100/100/500/2,500/20,000/200,000/4,000,000
Price increases:1,000/5,000/10,000/12,000/18,000/26,000/32,000/42,000

The multiplier from buying 10 Antimatter Dimensions is reduced to ×1. This increases by ×0.2 per Dimension Boost, to a maximum of ×2, and is unaffected by any upgrades.

Dimension Boosts provide no multiplier and Antimatter Galaxies cannot be bought. Dimensional Sacrifice resets antimatter and all Antimatter Dimensions, but also gives a significantly stronger multiplier.
The two provide no multiplier, but you still unlock Dimensions. For the improved formula, see Dimensional Sacrifice. This lets a superexponential loop occur with the help of Tickspeed.
During this challenge, only 5 Dimension Boosts can be bought.
Eighth Dimension Autobuyer

Whenever you buy Tickspeed upgrades or 10 of an Antimatter Dimension, 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)

There are only 6 Antimatter Dimensions. Dimension Boost and Antimatter Galaxy costs are modified.
Dimensional Sacrifice is effectively disabled as there is no Eighth Dimension available. For the modified costs, see Dimension Shift and Boost and Antimatter Galaxy.
Dimension Boost Autobuyer

There is normal matter which rises once you have at least 1 2nd Antimatter Dimension. 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 + \frac{b}{200} + \frac{g}{100})^{10}x rate per second, where b is Dimension Boosts and g is Galaxies.

Each Antimatter Dimension produces the Dimension 2 tiers below it instead of 1. Both 1st and 2nd Dimensions produce antimatter. The 2nd, 4th, and 6th Dimensions are made stronger to compensate.
Dimensions 1 and 2 produce antimatter, D3 produces D1, D4 -> D2 etc. Second Dimension's effectiveness is raised to the 1.7 and amount's effect on its production is raised to the 1.5.
Fourth Dimension's power is ^1.4 and amount's effect on production is ^1.3.
Sacrifice only resets the first 6 Dimensions since the Seventh Dimension cannot be naturally produced.
