Experiment: Neutral
The Neutral experiment is one of 12 experiments in the laboratory, available when the laboratory is first built.
The goal of the neutral experiment is to expand a sphere.
Mechanic
Upgrades increases how fast the sphere grows. Each tier of upgrades costs more, but also expands the sphere faster. When you buy enough of a single tier, the base rate of that tier will also increase.
Expanding converts current growth into maximum growth, which resets the sphere back to size 0.
| Upgrade | Base rate | Cost |
|---|---|---|
| Essencer | 0.1/s | 1 * triangle(lvl) * 2prestige
|
| Combiner | 0.5/s | 10 * triangle(lvl) * 2prestige
|
| Dragger | 1.5/s | 50 * triangle(lvl) * 2prestige
|
| Forcer | 4/s | 150 * triangle(lvl) * 2prestige
|
| Purer | 10/s | 500 * triangle(lvl) * 2prestige
|
| Condenser | 50/s | 2000 * triangle(lvl) * 2prestige
|
where triangle(lvl) = lvl*(lvl+1)/2 + 1.
As you buy more upgrades in a tier, the base rate of that tier starts getting multiplied based on how many upgrades you've bought. This makes it better to focus on a single tier, rather than spreading your upgrades among all the tiers. The multipliers follow a simple pattern, until it switches at high amounts:
| Count | Rate multiplier |
|---|---|
| 0 | 1x |
| 10 | 2x |
| 15 | 4x |
| 20 | 8x |
| 50 | 16x |
| 100 | 32x |
| 150 | 64x |
| 200 | 128x |
| 500 | 256x |
| 1000 | 512x |
| 2000+ | 2^(8.8+0.2*floor(count/1000))x
|
The purchase limit for each component (without any purchase limit prestige upgrades) is as follows:
| Component | Purchase Limit |
|---|---|
| Essencer | 60000 |
| Combiner | 50000 |
| Dragger | 40000 |
| Forcer | 30000 |
| Purer | 20000 |
| Condenser | 10000 |
Prestige
Prestige resets all generators and your maximum orbs to the square root of your current maximum orbs (capped at 10) and you have to choose between 2 bonuses.
- Production x2 - generators will produce orbs twice as much
- +5% max. Level (multiplicative) - increases the maximum levels by 5% of the previous maximum amount
Prestige becomes available when all upgrades are maxed at their highest levels. The base highest level for each upgrade is 10000 * (7 - tier). E.g. the initial maximum for Essencer, the tier 1 upgrade, would be 60000.
Because of the exponential nature of the bonus rate increase, the +5% max level quickly starts giving more than 2x production, and this just gets more pronounced the more you keep taking it.
This means that it is recommended to first start putting points into the 2x upgrade and later reset and swap all points to the x1.05 upgrade.
