Sedecordle strategy: how to solve all 16 boards in 21 guesses
To solve Sedecordle reliably, split your 21 guesses into three phases: about four guesses to collect letters on every board, about twelve to solve the boards that are already clear, and the last few for the hard boards, which by then have clues from every earlier row. Never spend a guess on a 50/50 board while another board has only one possible word.
This guide walks through each phase, with a real puzzle as the example, and ends with a checklist you can keep next to the game.
The guess budget
Sixteen boards need at least sixteen guesses, one per word, so the game gives you five spare guesses. That is the whole margin for the entire puzzle. Every opening word that doesn't solve a board uses one, and so does every wrong attempt at a board.
Thinking in terms of a budget helps. If you play four opening words, you have one spare guess left for mistakes. If you play three, you have two. Players who lose usually haven't made one big error; they have spent the spare guesses one by one without noticing.
Phase 1: collect letters (guesses 1–4)
Start with words that use common letters and no repeats. In English, AROSE, UNLIT, DUCHY, GIMPY cover 17 letters between them. Our article on the best starting words shows how that set was chosen and lists strong single openers.
Here is why the opening matters so much. We played those four words on all sixteen boards of puzzle #1 and counted how many of the game's 2,779 possible answers still fitted each board afterwards:
| Board | Possible answers left |
|---|---|
| 1 | 1 |
| 2 | 1 |
| 3 | 1 |
| 4 | 1 |
| 5 | 2 |
| 6 | 1 |
| 7 | 1 |
| 8 | 2 |
| 9 | 1 |
| 10 | 2 |
| 11 | 1 |
| 12 | 2 |
| 13 | 1 |
| 14 | 1 |
| 15 | 1 |
| 16 | 1 |
On 12 of the sixteen boards only one word was still possible, and no board had more than 2 candidates. You won't always see numbers this clean, but after four good openers most boards are down to one or two words, and that's what makes 21 guesses enough.
Phase 2: solve the clear boards (guesses 5–16)
Now go through the boards one by one and solve every board where only one word fits. Each correct guess solves that board and still colors the tiles on every other unsolved board, so you keep learning while you clear the easy ones.
Some habits that save guesses:
- Read every board before you type. A board you skimmed past often has a single obvious answer.
- Use the keyboard map. Each key shows a tiny 4×4 grid, one square per board. A key that is gray on a board means that letter is ruled out there; a key that has faded on every board can be ignored.
- Tap a board's number to focus it. The keyboard then shows the colors for that board only, which makes a tricky board much easier to read.
- Prefer guesses that help twice. When two words fit a board, pick the one whose letters also split the possibilities on another board.
Phase 3: the hard boards (guesses 17–21)
The boards left at the end are usually the ones with repeated letters or several similar words, such as _ATCH or _IGHT patterns. The good news is that they have now seen every letter you've played, so they carry far more clues than they did at the start.
When a board still has two or three candidates:
- Count your remaining guesses against the remaining boards. If you have exactly one guess per board, you can't afford to experiment.
- If you have a spare guess, consider a "splitter" word that contains the letters that differ between the candidates, even if it can't be the answer.
- Solve the boards you are sure of first. A 50/50 should be the very last thing you guess, never something that blocks a sure board.
If you are on the last guess with two boards left, you can only win one of them. Pick the board where you are more confident and accept the loss on the other: a 15/16 still keeps your stats honest.
Hard mode and the other modes
Hard mode requires every guess to fit at least one unsolved board. It stops you from using pure "splitter" words, so the opening phase matters even more. Choose openers that are real answers, and switch to solving a little earlier.
Sedec-order and Savior change the plan in their own ways: in Sedec-order the boards open one at a time and you get 23 guesses, and in Savior four guesses are already played for you. Our guide to both modes covers the adjustments.
A checklist for every game
- Plan your openers before you start and stick to them unless a board solves itself.
- After the openers, solve every board that has only one possible word.
- Use each solving guess to help other boards when you have a choice.
- Keep an eye on spare guesses: openers plus mistakes must stay within five.
- Leave coin-flip boards for the very end.
The best place to practise this is practice mode, where you get a new set of sixteen words whenever you want and nothing affects your daily streak. When you feel ready, take the plan into the daily puzzle.
