Challenges

**Challenges** is a Dark Matter+ feature that requires 8,000,000 Dark Matter to unlock. When the upgrade is bought, it doesn't consume your Dark Matter [as it says "Req", short for "Requires", which can mean either not affecting or setting it to 0 like Dimensions].

**Unlock Challenges**
Req: 8,000,000 dark matter
*The button itself.*

Upon entering a challenge, various restrictions are placed upon you, like not being able to buy Antimatter upgrades. In all challenges, DMU1 and DMU2 are disabled. These make it harder to progress. Each challenge also has a goal, in universe size. Once you get to that goal, you can complete the challenge. Once the challenge is complete, the reward for the challenge is applied, making it easier to progress, both in normal play and in challenges.

Challenges can be extended with 40,000,000 Dark Matter, giving access to 3 more challenges.

## Challenge 1

### Effects

*"Both antimatter upgrades are disabled"*

Both AMU1 and AMU2 cannot be bought, making it significantly harder to get to D5.

### Reward

*"Dark matter buyable 2 is x100"*

This multiplies the effect of DMB2 by 100.

## Challenge 2

### Effects

*"Upgrade 2's cost scaling is a lot worse, upgrade 5 is useless"*

U2's cost scaling is changed from changing by a complicated formula,

1.2

U

U

{\displaystyle 4+1.2^{(U2-10+2\*U5)(log(3)\*10)-2}}

 , to a much more simple

U

2

1.3

0.13

{\displaystyle U2^{1.3}+0.13}

, both in log, where

U
2

{\displaystyle U2}

 is the number of times U2 is bought and

U
5

{\displaystyle U5}

 is the number of times U5 is bought. Thus, U5 is indeed useless in this challenge.

### Reward

*"Upgrade 5's base is increased by 0.5"*

U5's base is increased by 0.5, making it stronger.

## Challenge 3

### Effects

*"Dimensions are useless"*

You can't buy dimensions.

### Reward

*"Dimension scaling is weakened"*

Divides Dimension scaling past 5 dimensions by 1.05

## Challenge 4

### Effects

*"Antimatter is much stronger"*

Antimatter effect is changed from

(

m
94

100

)

2

{\displaystyle \Bigr(\frac{m + 94}{100}\Bigr)^{2}}

 to

(
m
−
5

)

1.25

{\displaystyle (m-5)^{1.25}}

, where

m

{\displaystyle m}

 is the universe size in log.

### Goal

5.4e20 m

This was actually intentionally lowered as to make it not turn into a timewall.

### Reward

*"Divide second antimatter boost by 1.2"*

The second AM boost present at 1e1,000 meters is divided by 1.2. It's like the AMU2 for the second boost, only weaker.

## Challenge 5

### Effects

*"Only upgrades 1 and 3 exist"*

You can only buy upgrades 1, 3 , dimensions, antimatter upgrade 1.

### Reward

*"None"*

Does nothing.

## Challenge 6

### Effects

*"Dark matter boost is divided by 10"*

The Dark Matter boost is divided by 10. This actually makes Dark Matter root your expansion most of the time.

### Reward

*"None"*

Does nothing.

## Challenge 7

### Effects

*"**EVERY PREVIOUS CHALLENGE AT ONCE** and challenge completions boost universe size gain"*

Every effect of every previous challenge applies here, but C2's effect is useless with no U2 to speak of.

### Reward

*"Your dark matter gain is multiplied by objects + challenge completions"*

Since this is only unlocked after achieving a certain Subjective Milestone, the mentioning of objects is indeed intentional. The gain that you get for resetting for Dark Matter or your passive gain is multiplied by Objects + challenge completions.
