The Elided archive

Past puzzles, still playable — and still consequential. Every date carries one ranked attempt, ever, including the ones behind you: finish an archive day and it seals exactly like today's. Open a date you have already played and you get your record back, not a new board.

Each day plants the same three rounds for everyone from a fixed seed, and plays by exactly the rules today's does — how to play sets them out in full.
