  • Fill all 9 cells with the correct Fire Emblem unit.
  • You have only 10 guesses — once used, a guess is gone even if wrong.
  • There are at least 2 valid answers per cell. May not apply to creator submitted puzzles!
  • Once you place a unit, you cannot reuse them in another cell.
  • Units must satisfy both the row and column category to count.
  • Units data is taken from their initial appearance. Reclassing etc. is not taken into consideration.
  • Your Uniqueness Score is the sum of pick percentages across all cells. Each cell contributes the % of players who chose the same unit for that cell. Lower score = rarer picks = better score!
  • An empty or failed cell adds 100 points to your score.
  • New puzzles every day at midnight local time.
  • Hover over any category to see a fuller description of what it means. Categories with a small icon in the corner also link to Serenes Forest or Fire Emblem Wiki for more info.
  • Found a bug or have feedback? The game is in early development — data errors are possible!

How to earn puzzle submission tokens

What are tokens?

Tokens let you submit a custom puzzle for potential inclusion as a featured FEDOKU daily. Each token grants one submission.

How do I earn tokens?

There are currently two ways to earn tokens:

1 — Data corrections. Help fix unit data errors. When a unit in the puzzle has incorrect information, you can flag the bugged field and submit what you think the correct value should be. Each correction that gets approved — automatically by community consensus or manually by an admin — counts toward your total. Reach 50 approved corrections and you earn 1 token. Every additional 50 earns another.

2 — Ko-fi donation. Supporting FEDOKU on Ko-fi grants 1 token per donation or subscription payment. ⚠ Important: the email on your Ko-fi account must exactly match the email you use to sign into FEDOKU. If they differ, the token cannot be assigned automatically.

How does a data correction get approved?

Two ways: if 20 or more players have submitted a correction for the same flag and 90% or more agree on the same value, it is approved automatically. Otherwise, an admin can manually review and approve it.

How do I avoid wasting my time on corrections?

Submit only what you genuinely know to be correct. If your answer differs significantly from the final approved value, it will be marked as low-effort and will not count toward your total.

How do I use a token?

Once you have a token, a "Submit Puzzle" option will appear in the Puzzle Creator. Build your puzzle, find valid categories, then submit it for review.
