RollerCoin league calculator
Staying at the top of your league pays more than sitting at the bottom of the next one, where competition is tougher. The RollTheCal optimizer builds your room with your miners and racks to get as close as possible to the league limit, without passing it.
What it calculates
- League power, with the same formula as the game: miners × (1 + unique miner bonus) + rack bonus. Freon, games and temporary bonuses don't count.
- Your league limit, filled in automatically from your profile's league (Bronze I to Legend).
- The best room below the limit, leaving only the minimum margin you choose (default 300 Ph/s).
- The step by step: which miners to remove, move and place, room by room and slot by slot.
Three ways to optimize
| Button | What it does | When to use it |
|---|---|---|
| ＋ Add only | Doesn't remove or move anything in the room. Only places miners and racks from your inventory in free spots. | When you don't want to touch your room. |
| ⟳ Rearrange all | Can remove, move and swap every miner and rack. | For the best possible result. |
| ％ With minimum bonus | Same goal, guaranteeing at least the bonus you choose. | When the bonus matters for other things (for example, mining power). |
A real example
A Platinum II account (100 Eh/s limit) was at 99.83 Eh/s. With the miners stored in its inventory, the optimizer reached 99.988 Eh/s, and the game's league bar showed exactly the same value. That's 158 Ph/s more without changing leagues.
Why keep a margin
Your league moves up based on your power record. If at any moment your room passes the limit (for example, placing a miner before removing another), you move up and don't come back by removing miners afterwards. The minimum margin protects you against rounding and against those swap moments. Learn more in the guide How to stay at the top of your league without moving up by accident.
How to use it
- On the home page, type your profile name (what comes after
rollercoin.com/p/) and click Analyze. - Paste your inventory in the Inventory tab so the optimizer can use your stored miners and racks.
- In the Room & Simulator tab, pick one of the three buttons and follow the step by step in the game.
RollTheCal never asks for your password and never touches your account: it only uses your public profile data and what you paste.
