04 / FIELD NOTES & FAQ
Field notes from the table.
How does a sealed-bid auction work?
Each player submits one hidden bid. The highest bid wins; ties go to the earlier player in the setup order. In first-price mode the winner pays their bid. In second-price mode the winner pays the second-highest bid. In all-pay mode everyone pays their bid. Zero bids are allowed. The tool records currency settlement; award the auctioned item using your board game’s rules.
How do private trades work?
Offer one resource in exchange for another. The offered amount is reserved immediately. Only the recipient can accept or decline inside their vault. Acceptance checks the recipient’s balance and settles both sides together. Declining refunds the sender. Finish the auction before making trades.
Can I use this with any board game?
Use it for games whose rules allow hidden resource counts, classroom economy activities, TRPG sessions, and prototypes. Agree on the visibility rules first. This companion never changes the official rules of your game. Scores in the final ledger are a simple sum of resource units, not an official victory formula.
Is my vault encrypted?
No. A game PIN gates the interface; browser storage and JSON backups are not encrypted. Anyone with device or developer-tool access may inspect the game. Shield the screen and use a trusted shared device. It is a game companion, not a secure financial vault.
Does it work offline?
There is no installable offline PWA here. Once loaded, game calculations run in the browser, but reopening the Blogger site requires a connection. Export a backup before leaving or clearing browser data.
