## Before 16 October 2026

## After 26 November 2026

From 27 November 2026 (No. 56) the 42 puzzles repeat in order, starting again from the first. Every value, its source and how it was chosen are in the [puzzle file](https://davazdah.com/puzzles.json).

A day earlier than your last game does not change your record.
