Tools FAQ
What these tools cover, and what they deliberately do not.
- Which tools are available?
- Fifteen tools across five worlds: Tetramon decks, collection tracking, pack odds, shop progression and the economy. Every card above opens the tool page that owns it.
- Are these tools based on current game data?
- The tools use the game data and mechanics available for the supported version. Individual tool pages explain their scope and limitations.
- Do I need to upload a save?
- No. Every tool takes the state it needs by hand, and anything you enter stays in your browser.
- Are Market Simulator results predictions?
- No. The Market Simulator explores possible Market Price paths under the game’s rules. It is a simulation of the rules, not a forecast of your shop. Open Market Simulator →
