Which rack goes where in RollerCoin
Racks aren't just for holding miners. Each rack has its own bonus, and that bonus applies to the miners inside it. Moving miners between racks can raise your power without buying anything.
How rack bonus works
The rack bonus is applied miner by miner:
rack bonus = miner power × bonus of the rack it sits in
This value is added to your league power. Unlike the miners' bonus %, the rack bonus is not multiplied by anything else: it only applies to the power of that miner.
The golden rule
Your strongest miners go in the racks with the highest bonus. Since the bonus is a percentage of the miner's power, putting a 5 Eh/s miner in a +5% rack pays much more than putting a 1 Ph/s miner in that same rack.
| Move | Gain |
|---|---|
| 5,000 Ph/s miner from a +3% rack to a +5% rack | +100 Ph/s |
| 25 Ph/s miner from a +3% rack to a +5% rack | +0.5 Ph/s |
| 2,000 Ph/s miner from a +0% (Regular) rack to a +7% rack | +140 Ph/s |
Rack sizes
- 6-cell racks have 3 shelves; 8-cell racks have 4.
- Most miners take 2 cells (a whole shelf). 1-cell miners share a shelf: two fit side by side.
- Grouping your 1-cell miners on the same shelf frees space for one more miner.
Rack examples
Racks from a real Platinum II room, with the bonus each one gives to the miners inside:
Rack images: RollerCoin. The number in the name is the number of cells.
In that room, the strongest miner (5 Eh/s) earns +250 Ph/s in the Biohazard (+5%), +200 Ph/s in a Fury (+4%), +150 Ph/s in a Jet-Black (+3%) and nothing in the Regular. That's a 250 Ph/s difference between the best and the worst spot, just by changing the miner's rack.
When it's worth swapping a rack
If you have a 0% (Regular) rack in your room and a better rack in your inventory, swapping usually pays off, especially if the miners in that rack are strong. The gain is the power of the miners inside × the difference in bonus.
Remember that swapping a rack means removing its miners first. Take your time and check your power at each step.
How RollTheCal helps
- ⟳ Rearrange all moves strong miners to the best racks and places good inventory racks in empty spots.
- ＋ Add only doesn't touch the miners already in the room; it only fills the free spots.
- ⇄ Optimize space groups 1-cell miners to free up shelves.
- In the room layout, each rack's bonus shows at its top, and the racks that change are shown in green.
For your inventory racks to be used, also paste the Racks tab of your inventory in the Inventory tab.
