Washing gold 1
| 15 sluice boxes | +1 to base sluice box production for every 20 sluice boxes owned | 5400 | 90 | 3 minutes | |

Washing gold 2
| 35 sluice boxes | +1 to base sluice box production for every 8 sluice boxes owned | 4.86 Million | 16200 | 15 minutes | |

Washing gold 3
| 75 sluice boxes | +1 to base sluice box production for every 3 sluice boxes owned | 8.7 Billion | 5.8 Million | 1 hr. 15 min. | |

Washing gold 4
| 155 sluice boxes | +1 to base sluice box production for every sluice boxes owned | 15 Trillion | 2 Billion | 6 hr. 15 min. | |

Washing gold 5
| 315 sluice boxes | +4 to base sluice box production for every sluice boxes owned | 40 Quadrillion | 1 Trillion | 1 day 7 hr. 15 min. |

Washing gold bonus can be calculated using the following formula:

**Washing gold ratio** depends on the level of the washing gold special ability. It will be 0.05 on the first level of the washing gold because it increases production by 1 for every 20 sluice boxes owned. And it will be 4 at the fifth level of the washing gold because it increases production by 4 for every sluice box owned.

For example if you have 90 sluice boxes and completed Washing gold 3 research your washing gold bonus will be 30 (90 * 1/3).

## Sluice Box Production Calculations Edit

Initial sluice box production can be calculated using the following formula:

where **SBP** is Sluice box base production (0.5 gold per second)

**WGB** stands for Washing gold bonus. It depends on the number of Sluice boxes player currently have and the level of Washing gold special ability. For example if player owns 90 sluice boxes and completed Washing gold 3 research, his WGB will be 30 (90 * 1/3) as he receives +1 bonus to sluice box production for every 3 sluice boxes owned.

**BSM** stands for Better sluicing multiplier. It depends on the level of Better sluicing production research. For example if player completed Better sluicing 3 research, his BSM will be 24 (2 x 3 x 4).

So if you have 90 sluice boxes and completed researches Better sluicing 3 and Washing gold 3 your result Sluice box production will be (0.5 + 30) x 24 = 732 gold per second.

Sluice box production can be further boosted by tower starting from level 2 and rocker's special ability Bathing gold.

Pit's special ability Digging gold also take a part in Sluice box production as it increases base production of all buildings in game.

So the final formula will look like this:

where **TM** is bonus from tower (increases sluice box base production starting from tower level 2)

**BGM** is Bathing gold multiplier (multiplier to sluice box base production from rocker's special ability)

and **DGM** stands for Digging gold multiplier (multiplier to all buildings base production from pit's special ability).
