How GrindMath works
Most game "value lists" tell you what a pet is worth in general. That isn't what you need when you're deciding what to do next. What you need is the answer for your pets: the exact weight on the card, the mutation it rolled, the boosts you own, and the cash you already have. Every GrindMath tool starts from what you type in.
Each tool also shows where its numbers come from and when they were checked. Game data changes with every update, and fan sources often disagree. When they do, we say so on the page, pick the better-supported number, and let you replace it with the one your game shows. Nothing is invented to fill a gap: if a number isn't known (like hatch odds that the developers haven't published), the tool asks you for it or leaves it out.
The calculators save what you enter on your own device, so they remember your pen next time. There are no accounts, and nothing you type is sent to us. See About & sources for who makes GrindMath and how the data is checked.
More games are on the way. Every tool shows where its numbers come from and lets you fix them when the game updates.
