Portfolio years vs one company

Erstwhile vs Compoundle, two daily investing games

Erstwhile spreads ten chips across a hidden five-year window. Compoundle asks you to invest, short, or pass on one historical company. Both are free browser puzzles. They are not the same decision.

Where they meet

Both use real historical companies, both reset daily, both run in the browser, and neither requires an account. Alldle files Compoundle under trivia, “Brands & products,” by O’Flaherty Bros. Games, listed since May 2026. Alldle describes the choice as invest, short, or pass on a historical company.

Where they split

Erstwhile is a mix. You are choosing weights, then living with them until year 2 and year 4. Compoundle is a stance on one name. If you want a yes/no/pass, Compoundle is the shorter object. If you want a portfolio you can regret in stages, Erstwhile is the one that publishes that structure.

I am not filling Compoundle’s outcome period, scoring, or archive. Those cells are empty on the pages I read. Guessing “also five years” would glue two games together.

Questions

Which is harder?

I do not have a shared score. Compoundle asks for a stance on a company; Erstwhile hides the year and then scores you against an index. Different hidden things.
