Daily logic puzzles, six ways to deduce
Six fresh logic puzzles every day at midnight Eastern. One streak across all of them.
Six fresh logic puzzles arrive every day at midnight Eastern. Play Sudoku when you want visible constraints, Kakuro when you want arithmetic, a nonogram when you want a picture to emerge — or work through all six and train a different kind of deduction each time.
DailyGrid's logic shelf is half of its ten-game daily set. There is no trivia and no vocabulary test: every clue you need is already on the board. Each puzzle is solver-verified, each new day is checked against everything DailyGrid has published, and solving any one game keeps your DailyGrid streak alive.
The daily puzzles are free. Always. No account, subscription, or download is required — open a puzzle in your browser and start deducing.
Pick by the kind of thinking you enjoy
| Game | What you do | The core deduction | How the week grows |
|---|---|---|---|
| 🔢 Grid (Sudoku) | Fill a 9×9 so every row, column, and 3×3 box contains 1–9 exactly once. | Eliminate candidates until a cell — or a digit's home — has only one possibility. | 45 givens on easy days, 36 midweek, 30 on hard days. |
| ➕ Kakuro | Fill white runs so they total their clues without repeating a digit in a run. | Intersect the combinations allowed by the across run and the down run. | 6×6 boards early in the week, 8×8 midweek, 10×10 on hard days. |
| 🖼️ Pixel (Nonogram) | Use row and column run lengths to reveal a hidden picture. | Find the overlap that remains filled no matter how a block slides. | 8×8 early, 12×12 midweek, 15×15 on hard days. |
| ➰ Slitherlink | Draw one unbroken loop that matches every numbered cell. | Turn local edge counts into a single global path — never a branch or a small side loop. | 5×5 early, 8×8 midweek, 10×10 on hard days. |
| 🌉 Hashi | Connect numbered islands with bridges until the map is one network. | Balance each island's bridge count against the need to keep the whole network connected. | Starts at 7×7 with 8–10 islands and grows to 12×12 with 16–20 islands. |
| 💣 Minesweeper | Reveal every safe cell and flag the mines without opening one. | Treat each number as an equation about its hidden neighbors. DailyGrid boards are verified logic-solvable, so a true coin-flip guess is not part of the design. | 8×8 with 10 mines early, 10×10 with 20 midweek, 12×12 with 30 on hard days. |
Start here if…
- You like numbers but not arithmetic: start with Grid.
- You like crosswords, but wish the answers were digits: start with Kakuro.
- You think in pictures: start with Pixel.
- You like routes, loops, and maps: start with Slitherlink or Hashi.
- You like uncovering hidden information one safe step at a time: start with Minesweeper.
A weekly circuit, not six copies of the same puzzle
DailyGrid uses the same rhythm across the week: Monday and Tuesday are easy, Wednesday and Thursday are medium, and Friday through Sunday are hard. That shape makes the six games work as a small training circuit.
- Numbers in plain sight — Grid, then Kakuro. Grid teaches candidate elimination. Kakuro adds sums, so the same cell must satisfy a set of digits as well as a total.
- Shape and boundary — Pixel, then Slitherlink. Pixel asks which cells must be filled. Slitherlink asks which edges must form the boundary. Both reward marking what is impossible, not just what is certain.
- Systems — Hashi, then Minesweeper. In Hashi, every bridge changes a visible network. In Minesweeper, every opened cell reveals information about a hidden one. One is construction; the other is inference.
On easy days, use the smaller boards to learn a new game's rules. Midweek, pair two complementary styles — Grid with Pixel, or Kakuro with Hashi. On hard days, pick the board that beat you and work it properly. Missed a day? Past sets remain in the puzzle archive, so a hard Sunday board can become next week's training puzzle.
Worked example: why Slitherlink players cross out the zeros first
From DailyGrid's archived Thursday, October 15, 2026 Slitherlink, an 8×8 board with 27 cells marked 0.
A 0 touches the loop on none of its four sides. Crossing out every edge of every zero therefore eliminates 73 distinct edges — some edges border two zeros and are counted once — out of the board's 144 possible edges. Before a single loop segment is drawn, more than half the board's edges are known not to be loop.
The zeros then corner a nearby clue. The 2 in row 3, column 6 has a 0 to its left and a 0 below it, so its left and bottom edges are already dead. A 2 needs exactly two loop edges, leaving only one possibility: its top and right edges are both loop.
That is the pleasure of the whole category in miniature: a local mark creates a forced move, the forced move changes neighboring cells, and a board that looked blank starts to unzip. DailyGrid's full Slitherlink strategy guide works through the corner and vertex rules that take over from there.
Four habits that transfer across all six games
- Mark impossibilities. Crosses, candidate removals, and empty-cell marks are progress. A smaller possibility space is a solved part of the puzzle even when no final answer has been placed.
- Work intersections. Almost every useful cell belongs to two systems at once: a row and a column, an across run and a down run, a numbered clue and the global loop. The overlap is where forced moves live.
- Recompute after every placement. One digit, bridge, filled cell, or flag changes the problem around it. Return to the neighboring clues before searching the far side of the board.
- Delay the glamorous technique. Most stalls are a missed simple deduction, not a missing advanced pattern. Make the cheap scan first; escalate only when it comes back empty.
Each game has a dedicated guide when you want the next level: Grid rules and strategy · Kakuro rules and strategy · Pixel rules and strategy · Slitherlink rules and strategy · Hashi rules and strategy · Minesweeper rules and strategy.
The logic set plays completely in Spanish
These six are DailyGrid's language-independent games. Switch the site to Español and the interface and game text switch with it; the puzzles themselves are built from numbers, symbols, and spatial rules rather than English answers. The four word games are the separate part of the daily ten whose puzzle content is currently English.
Make a solve into a challenge
After a win, DailyGrid gives you a spoiler-free result card and a challenge link carrying your time. Send it to a friend and they play the same puzzle under a "beat my time" banner. Private leagues let a family, classroom, or group chat keep its own daily standings. The mechanics are explained in How to Play.
Want all ten rather than only the deduction shelf? See all ten daily puzzles. Prefer words to numbers? The other shelf is the four daily word games — Word Search, Mini Crossword, Ladder, and Cipher. Run a site or newsletter? You can also embed a DailyGrid puzzle for your readers.
Honest limits
- In this category, "logic puzzle" means grid, number, path, network, and hidden-information deduction. It does not mean story-style "who owns the zebra?" elimination grids.
- Six of DailyGrid's ten games are logic games. The other four — Cipher, Ladder, Mini Crossword, and Word Search — are word games.
- This is a daily set, not an endless random-puzzle feed. The point is that everyone gets the same fresh challenge on the same day; older sets stay available in the archive.
- Streaks and progress are tied to the device you play on because there are no accounts. They do not yet carry automatically to a new phone or computer.
FAQ
How many daily logic puzzles does DailyGrid publish?
Six: Grid (Sudoku), Kakuro, Pixel (nonogram), Slitherlink, Hashi, and Minesweeper. They are part of a ten-game daily set that also includes four word games.
Are the puzzles really solvable without guessing?
DailyGrid solver-verifies its puzzles for a unique solution. The clearest example is Minesweeper: its live game page describes every board as verified solvable by pure logic, rather than depending on a lucky click. Across the category, the intended path is deduction — mark the forced moves, recompute, and repeat.
When do new logic puzzles appear?
At midnight Eastern, every day. The whole set follows a weekly rhythm: easy on Monday and Tuesday, medium on Wednesday and Thursday, and hard from Friday through Sunday.
Do I need an account?
No. There is no signup, email, or password. DailyGrid uses an anonymous device ID for progress, streaks, ratings, and leaderboard entries.
Can I play a puzzle I missed?
Yes. Past daily sets stay playable in the archive. An archive solve is useful practice and lets you revisit a hard board after its day has passed.
Are the daily logic puzzles free?
The daily puzzles are free. Always. That promise covers DailyGrid's daily ten, including all six logic games on this page.
