Overload Toolkit
Exact solvers for Overload gear rolling. Plan a whole four-piece set, work out the cheapest lock and reroll policy, and see what a target will really cost in rocks.
Calculators for NIKKE gear, Core Dust, dolls, and spending
I built these to answer questions that kept coming up while I played NIKKE, then put them here for anyone else who finds them useful.
Core Dust Planner
Where your Core Dust comes from and where it should go. A gem budget planner, a Synchro leveling calculator, and the numbers behind every source.
Doll Planner
Plan Collection Item upgrades for a full roster from the Maintenance Kits and dolls you have, with completion timing and level-by-level kit instructions.
Spending Guide
What is worth buying with real money. Pick the resources you care about and a budget, and get a value-per-dollar purchase ladder over the cash shop.
Recruitment
Recruitment odds for the copies you want from the pulls you have.
Progression
Upgrade costs and recurring income for Harmony Cubes, skill manuals, and other progression systems.
About the tools
Separate engines
Calculator logic lives in pure TypeScript modules, separate from the pages. Probability tools solve their distributions directly rather than sampling runs.
Local state
There is no backend or account system. Inputs are validated before they are saved in your browser, and every result is recalculated from those inputs.
Tested data
Game figures live in typed datasets with source notes. The unit suite checks known totals, edge cases, and dataset invariants.
Who made this
Yo! I'm Rucks. This started with one question I couldn't get a straight answer to, then another, and at some point I had a folder of spreadsheets and it seemed silly not to put them somewhere.
Most of the work is the boring part. Checking numbers against the game, reading patch notes, and redoing the math when something changes. Even so, I fat finger things all the time, so if you spot a number that looks off, tell me! It really helps to know when something slipped through. And if there's a calculator you wish existed, pitch it. I'd love to hear the idea.
