How well do you remember your decades?
Ten questions a day, across the 1960s to the 2000s.
Free forever
The Daily Rewind, your streak, the share card and the leaderboards are free every day, and are never interrupted by an ad. That is not an introductory offer.
Every question checked against a source
Each question in Decadia was independently re-answered by a second model and then verified against a retrieved, citable source before it was allowed into the bank. Anything that could not be sourced was thrown away rather than shipped.
No ad spam
At most one ad per session, after your results — never during a round. Premium removes them entirely, for $19.99 a year or $29.99 once. There is no weekly tier and there never will be.
