How to Use Hammy's RollerCoin Room Optimizer

Importing inventory from RollerCoin is simple once you get the hang of it, but it can be confusing the first time. I added a parser to the RollerCoin room optimizer to automatically parse your inventory, but it has to be input a certain way. This was designed to work on both desktop AND mobile so everyone can use it!

This is the location where your miners and other items are stored. Here, click on the "Miners" tab at the top, then change the "24" dropdown on the right to 48 to make this faster:

Scroll to the bottom while clicking "Load more" as often as you need to until you get to where you don't see any more messages.

Start your selection at the very bottom right of the last miner and drag all the way to the top left corner of the first miner, selecting all of the text. Copy using CTRL+C, holding to copy (mobile), etc. and just paste that in the Inventory importer! It'll look weird as it is, but the parser will break it all down for you and quickly get it into your inventory to use in your room!

What Referrals Gate, and What They Do Not

Worth clearing up before you go any further because this page is called the room optimizer and that is a part of Hammy that referrals unlock. The three steps above do not need referrals. Loading your miners, importing them, and building your room are open to everyone.

What referrals unlock is the auto-optimize feature -- the part that rearranges your room for the best base power in whichever league you are aiming at - along with additions made since. If you worked through the steps above and your miners imported, you have already done the part that is not gated. The referral change is explained in full here.

If you built a room in Hammy before any of this, nothing has been taken away from it. Your existing saved rooms are still there and still load. The gate applies to the auto-optimize feature and to newer additions, not to work you have already done.

About the Parser

The pasted text is meant to look unstructured. You are copying a block of RollerCoin text exactly as it appears, and the parser reads it back into individual miners in your inventory. "It will look weird as it is" is an accurate description of the step, not a sign that something has gone wrong.

As of 09/26/2026, the inventory is split into separate Miners and Racks tabs, each showing how many items it holds and how many unique miners and racks you own. Racks can be copied from your room into your inventory and imported back, and the inventory can be erased without touching the room itself.

Once you get this down, updating your inventory is super easy to do -- just keep repeating these steps as needed!
