How to play Archived Sudoku

Replay the classic 9×9 daily puzzle from a date in the Matte archive. Dates start September 8, 2026 and roll over at midnight UTC. The archive uses the existing daily generator, so a date keeps its original board.

Choose a date from Daily Games & Archive. Future dates are unavailable.
Fill each row, column and 3×3 box with 1 through 9 without repetition.
Use the same notes, Undo and progressive logical hints as classic Sudoku.
Progress saves separately for each archived date. Restart or replay gives the same dated board.
Archive completion is recorded locally and does not add to the classic daily streak.

A tip for your next game

An archive is a useful place to revisit a technique without replacing your current classic save. A shared result link includes the original UTC date.

Common questions

Does archived play change my daily streak?

No. It has a separate local completion record. The original daily entry retains its own UTC streak rules.

Can I play tomorrow’s puzzle?

No. Only dates from the archive launch through today UTC are selectable.

Will my progress survive a date change?

Each archived date has its own browser save. Returning to its URL restores unfinished entries and notes unless browser data was cleared.
