Sedec Guess Beginner Tips: Solve Sixteen Words in Twenty-One Shared Guesses (2026)

Last updated: October 2, 2026 · Tested on Playnesta's Sedec Guess build (self-built 16-board engine, word lists from WebDevSimplified/wordle-clone @ b12c2df) · Goal: solve sixteen hidden five-letter words in 21 shared guesses

Method: every rule below was verified against this site's playable build — constants read from the shipped game (16 boards x 21 rows x 5 tiles, 1680 tiles total, 26 on-screen letter keys, 2315 target words plus a 12972-word dictionary, sixteen words per calendar day counted from 2022-01-01, one guess filling every unsolved board at once, green = right letter in place / yellow = right letter elsewhere / gray = absent, the keyboard keeping the best state per letter across all sixteen boards, a solved board no longer accepting letters), and a headless-browser run confirmed a clean start with zero errors, a sixteen-word daily set with no duplicates, a rejected word keeping its row, one guess colouring all sixteen boards, a solved board going inert, all sixteen answers closed with the "You Win" banner on the final allowed row, a twenty-one-row exhaustion naming all sixteen missed answers, and 4x4 boards at 390px with no sideways scroll. Controls: type lowercase letters and press Enter on desktop, or tap the on-screen keyboard on touch screens. The sixteen-board entry in this station's word-guess family.

1. Twenty-one rows for sixteen words is the tightest ratio in the family

The arithmetic is the whole game: 21 shared guesses for sixteen answers is 1.31 rows per word. Compare that with the smaller puzzles on this site — the two-board game gives you 3.5 rows per word and the eight-board game 1.63 — so Sedec Guess leaves the least slack of the set. Concretely: if the sixteen answers were all you ever guessed, you would need exactly sixteen rows and would have only five spare rows for the entire run. Anything that is not solving a board is spending one of those five.

2. Open for coverage across all sixteen boards, not for a favourite word

A themed or lucky opener wastes the multiplier. The reason to play sixteen boards at once is that one guess is scored against every board you have not solved: on this build a single row shades up to 80 tiles (5 per board x 16 boards), which is what several separate single-board games would have cost you. So pick five letters that are likely to appear in some of the sixteen answers — a vowel spread plus workhorse consonants — and let the colours do the sorting. Because the answers are sixteen different words drawn in order from the same 2315-word list, a well-chosen opener tells you something about many boards at once; a favourite word tells you about one.

3. Close the boards that are nearly done — they stop charging rent

A solved board freezes: it stops receiving your letters, so every later guess is spent entirely on the boards still open. That is not a cosmetic win — it is how the 1.31 ratio becomes survivable. On the verified run for this page, the first board closed on the sixth row and the remaining rows never touched it again; the finish came on the 21st and last row precisely because thirteen of the sixteen boards had already stopped participating. A board sitting on four green letters that you keep ignoring still looks like progress while quietly consuming a slot on every remaining row.

4. Read the keyboard, not the 1680 tiles

Scanning sixteen boards tile by tile is the fastest way to lose. The on-screen keyboard keeps the best state any letter has reached across every board — green beats yellow beats gray — so it is a far shorter summary than 1680 tiles. Letters marked gray everywhere are dead in all sixteen answers: never give them another slot. Letters the pad has not marked yet are the useful ones, which is how you choose the next probe instead of recycling guesses. The shared keyboard is also the only place where "which letters have I already ruled out globally" is legible.

5. A rejected word keeps your row — but only your row

The game only accepts its 12972-word dictionary. Type a made-up string and the row shakes with "Not in word list" while the letters stay put, so the guess is not consumed by the counter — but with five spare rows in the whole run, the time you spend on a typo is the least of it. Delete the wrong letters with Backspace (or the on-screen backspace key) and submit a real word. Short rows are caught separately with "Not enough letters".

6. Know exactly how the run ends

Solve all sixteen boards and the page announces it and stops taking input — including when the sixteenth word falls on your very last allowed row, which is announced as a win rather than a loss. Use all 21 rows and the run ends by naming every word you missed, so a loss still hands you the answers. There is exactly one set of sixteen words per calendar day: replaying reloads the same sixteen words until midnight, which turns a lost run into a free rehearsal instead of a closed door.

FAQ

How do I play Sedec Guess?

Type five letters and press Enter, or tap the on-screen keyboard. Your guess is scored against every board you have not solved yet: green is the right letter in the right place, yellow is in the word but misplaced, gray is absent. You have 21 shared rows to solve sixteen words.

Is this the same as other daily sixteen-word puzzles?

It is the same genre — a sedecordle-style daily puzzle where one guess serves many boards — rebuilt here from scratch as Sedec Guess on this site's own word-guess engine, with its own interface and its own daily set of sixteen words.

How is it different from the two-, four- and eight-board puzzles on this site?

Duo Guess asks for two words in seven rows, Quad Guess for four in nine and Octo Guess for eight in thirteen. Sedec Guess is the largest of the family and the tightest per word: 21 rows for sixteen answers leaves only five spare rows in the whole run.

What happens when I use all 21 guesses?

The run ends and the page spells out every answer you did not reach. Tap the replay bar for a fresh attempt at the same sixteen words.

Do I get new words every day?

Yes — one set of sixteen words per calendar day, counted from January 1, 2022. The words are taken from the same 2315-word list in order, so replaying before midnight reloads exactly the same sixteen.

Does it work on mobile?

Yes — the sixteen boards are laid out 4x4 above the shared keyboard (tiles measure about 12.7px at 390px wide), the on-screen keys feed the same input path as a physical keyboard, the backspace key deletes, and the page measures 390px wide with no sideways scroll.

Where can I play it?

Right on this site's sedec-guess page. The engine is self-built and the word lists come from the MIT-licensed wordle-clone by WebDevSimplified; license and attribution are listed under the game.
