About this guide to the daily investing game
erstwhile.pro explains the daily investing game published at erstwhile.io. The game is not operated from this domain. Corrections go to [email protected].
What this site is for
Search results for the name mix up a browser puzzle, a Steam roguelike, a 2018 story, a jeweler, and a record label. These pages stay on the puzzle: the rules, the paid extras, the archive policy, and the neighboring daily games. They do not sell chips, and they do not log into the game.
The writing is mine, dated, and tied to public pages. When two sources disagree I keep both. When a number is only my count from public puzzle numbers, I say derived. The asset table is the public pool, not a tip sheet.
Who you are writing to
The mailbox is [email protected]. That address is the editorial contact for this domain. The game’s own support address, printed on its FAQ and privacy pages, is [email protected]. Use that one for a lost purchase or a sign-in problem on the game. Use this one for a wrong sentence on erstwhile.pro.
