Balance an indie RPG or idle game economy before launch
Most economy problems show up as "I hit a wall at level 30" or "gold is worthless by day 5". Grindscale shows both before players do: the 60-day simulator tracks a typical player's level and wallet each day.
How games teams use Grindscale
- Load the preset closest to your game (classic RPG, mobile casual, long-haul RPG or roguelite meta).
- Enter your real XP rewards and gold faucets and sinks; watch the wallet and inflation warnings on the Economy sheet.
- Set shop prices from "hours of saving" at each item's unlock level.
- Add loot tables with pity and check tries for 90% on the Drops sheet.
- Export per-level CSV/JSON and load it with the included engine loader.
The workbook is a design aid, not analytics: once you have players, compare the simulator with real data and adjust.
