**Daily challenges** are a special type of challenge which are comprised of a random set of predefined rules. It will appear in the list of challenges in the Portal screen once the player has reached zone 100 (or zone 30 for U2).

Daily challenges do not have a specific end point; they end when the player chooses for them to end. Each day spawns a new challenge with a set of randomly generated rules and a reward modifier based on the overall difficulty of the modifiers. Being in a Daily Challenge will grant a passive multiplier to most non-helium resources (including Nullifium, Dark Essence and Fluffy/Scruffy Exp) gained throughout the run by the reward modifier, while finishing it will multiply all Helium earned based on the reward modifier. This makes all daily challenges Helium challenges.

## Overview

When Daily Challenges are unlocked, a new button will appear in the list of challenge called Daily. Clicking it will select the challenge of the specific day. The player is also allowed to view and run the challenge of the previous 6 days by clicking the respective days, assuming they haven't been completed already.

Once started, **the player can spend as long as they want on the challenge itself**. You do not have to finish the challenge before the time at which the next week's Daily Challenge is rolled. If you start a challenge on Monday and finish it next Monday, all challenges from the previous week will still be accessible. This means there is a maximum possible buffer of having Eight daily Challenges at once (7 in menu + 1 being currently run).

When in a Daily Challenge, the Abandon challenge function is replaced with the Finish Daily function. Each Daily Challenge can only be started once.

The challenge ends either when the player presses the Finish Daily button or if they Portal. Using the button will allow the player to spend the Helium earned in the run and the bonus Helium in the Portal screen. Using the Portal without finishing the challenge first only lets the player spend the base Helium on Perks, and then the bonus Helium can be spent later in the View Perks menu.

The game uses UTC time to determine when a new day starts.

## Rules

Each Daily Challenge includes a variety of randomly generated rules. The number of rules that can appear at once is technically constrained, however there is no hard cap.

### Extra Notes

Famine has the highest chance of being one of the modifiers. Bogged, Crits, Dedication, Weakness and Plague all have a lower chance of being one of the modifiers.

Some daily challenge modifiers are now incompatible with each other. This includes:

* Trimp Crit Chance Up and Trimp Crit Chance Down
* Dedication and Famine
* Bogged/Plague (effects killing Trimps quickly) and Rampage/Weakness (effect depends on Trimps being alive)

The damage reflected to your Trimps by the Reflect modifier cannot be blocked. On the contrary, the damage from Explosive can be blocked but will pierce depending on the zone you're currently on.

Empower stacks are applied whenever your current group of fighting Trimps are killed (by enemies, by reflected damage). Deaths from Omnipotrimp explosions are excluded.

Mutimps have 3x attack and 6x health, and are fast. Hulking Mutimps have 5x attack and 12x health, and are also fast. Both reward Metal when defeated.

It is possible for enemies with Crits to have their critical damage stack with critical damage from Crushed, or from Corrupted Precision/Healthy and Precise.

With the new Trimp Crit Chance modifiers, it is possible for Trimp Crit Chance to fall below 0%, or go above 100% (or even 200%!). Check this section for more details.

## Rewards

When finished, either manually or by using the Portal, a Daily Challenge will give an amount of Helium which depends on its multiplier and the amount of Helium the player has earned in the run. Like with other Helium challenges, Helium spent on Wormholes does not lower the final bonus Helium gained from completing the challenge.

Nulifium earned from Heirlooms will also be increased by the same percentage as Helium for however long the challenge is active. Heirlooms carried over from previous runs will not gain the Nulifium bonus.

**The bonus Helium from any Daily challenge will not count towards the Bone Trader's Portal purchase.** However, the base Helium still applies. For example, if you earn 8M Helium before finishing the challenge and gain 22M bonus from finishing it for a total of 30M Helium, only 8M Helium will be counted towards the Bone Portal.

### Weight

Every daily challenge rolls for a list of random modifiers using various factors. The generator aims to pick a selection of mods for a total weight between 2.0 - 5.0, and is allowed a 0.5 margin of error. It can also occasionally roll beyond 5.5.

Note that this range is not a linear distribution. The generator generally aims to fill the challenge with at least a large and a medium sized modifier, meaning it will rarely end up with a low total weight value. See the tables above for selected weights for modifiers.

Once all modifiers are chosen, the sum of all weights of all modifiers is the total weight value of the challenge.

### Helium reward

The total weight value directly corresponds to the final Helium reward, and is the result of the following calculation:

**Bonus Helium % = (75 \* weight) + 20**
The baseline bonus Helium cannot go below 100%, and cannot exceed 500%. Fluffy and Scruffy both have abilities that increase Daily reward value in their respective Universes, which simply adds a flat 100% to this result.

Below is a table of **selected** weights and their corresponding Helium rewards.

 2.0
 3.0
 4.0
 5.0
 6.0

### Other Rewards

While in a Daily Challenge, Fluffy/Scruffy EXP gain is increased by an amount equal to the bonus Helium/Radon percentage.

As of 5.2, the Daily Modifier also affects Nu from Heirlooms, Nature Tokens, and Dark Essence. It should be noted that only Heirlooms obtained during the daily are affected - Heirlooms obtained beforehand will not be worth more Nu during a Daily, likewise Heirlooms earned during a Daily will keep their modified Nu value if stored.

## Trivia

* When introduced, contrary to other Helium challenges, the bonus Helium gained from completing a Daily Challenge would not count Helium spent on Wormholes, instead, it would multiply the current Helium number earned in the run. This was later changed to instead work like other Helium challenges, granting a lump sum of helium all at once.
* Daily Challenges were added in patch 3.8.
* In patch 4.3, one can now run any Daily Challenge from the past 7 days (up from 2 previously). Also 5 new modifiers are added.
* In patch 4.8, two new modifiers are added (Trimp crit chance up/down). Also, conflicting modifiers, such as Trimp Crit Chance Up and Trimp Crit Chance Down, can no longer appear in the same Daily Challenge.
* In patch 4.10, Plagued and Bogged are made to spawn less frequently (about once per week on average).
