Frequently asked questions
Answers about calculation methods, data protection, and effects.
Why is my result different from another calculator?
Different opening-hand sizes, first-turn draws, mulligans, search costs, and action orders produce different results. Compare the settings summary and calculation method first.
What is the difference between exact calculation and simulation?
Exact calculation gives the mathematical answer for a simple condition. Simulation estimates a complex sequence and reports a 95% confidence interval.
Is my card data sent to a server?
No. Projects, card names, and results are stored only in your browser's IndexedDB. Shared project data is compressed into the URL.
Does this support a specific TCG?
The model is game-agnostic and does not include official card images or card databases.
How do I configure a search card?
Give the card and its search effect the same target tag. Enter costs and action order to match real play.
Can I use it on mobile?
Yes. Inputs and results use a responsive layout designed to keep actions accessible on smaller screens.
