What Is Daily Loop?
Daily Loop is a free browser-based logic puzzle developed by Zygomatic. Based on the classic Slitherlink puzzle format, it challenges players to draw a single continuous closed loop by connecting dots on a rectangular grid.
The board contains numbered cells that tell you exactly how many of their four surrounding edges must belong to the final loop. Your job is to work out which lines to draw and which edges must remain empty.
For example, a cell marked 3 must have exactly three surrounding line segments, while a cell marked 0 must have none. These simple numerical clues interact with one another, gradually revealing the shape of the hidden loop.
The most important rule is that the completed drawing must form one single closed loop. It cannot branch, cross itself, contain loose ends, or split into separate circuits.
Daily Loop offers fresh puzzles every day across four size and difficulty options, making it suitable for beginners and experienced logic-puzzle players alike.
Daily Loop Game Rules
The objective is to create one uninterrupted loop along the edges of the grid while satisfying every numbered clue.
The main rules are:
- Connect the dots: Draw horizontal or vertical lines between neighboring dots.
- Follow the numbers: Each numbered cell must have exactly that many of its four sides included in the loop.
- Zero means no lines: A cell containing 0 cannot have any of its surrounding edges drawn.
- One means one line: A cell containing 1 must have exactly one surrounding edge drawn.
- Two means two lines: A cell containing 2 must have exactly two surrounding edges drawn.
- Three means three lines: A cell containing 3 must have exactly three surrounding edges drawn.
- Empty cells: Cells without numbers have no individual side-count requirement, but they must still fit the completed loop.
- One continuous circuit: All drawn line segments must belong to a single closed loop.
- No branches or crossings: Every dot used by the loop must connect exactly two line segments.
- Not every dot is required: The loop can leave some dots and edges unused.
A puzzle is complete only when all numbered clues are satisfied and the drawn path forms one valid closed circuit.
How to Play Daily Loop
- Choose your puzzle size: Open Daily Loop and choose one of the available daily challenges. Smaller grids are generally easier, while larger boards require more deduction.
- Study the numbered cells: Examine the grid before drawing anything. Look for zeros, threes, and neighboring clues that immediately restrict the possible line placements.
- Draw or exclude edges: Click or tap between two adjacent dots to draw a line. Click the same edge again to mark it with an X, indicating that no line belongs there. Click a third time to clear the mark.
- Continue solving logically: Use the numbers and the requirement for one continuous loop to determine additional edges. Watch for conflicts, such as too many lines surrounding a clue or three lines meeting at one dot.
- Complete the closed loop: Continue until every numbered cell has the correct number of surrounding lines and the entire drawing forms one closed circuit. The game displays your completion result and solving time.
Example: Understanding the Numbered Clues
Daily Loop is based on counting line segments around individual cells.
Imagine two neighboring cells. The left cell contains 3 and the right cell contains 0.
+---+ +
| 3 0
+---+ +
In this simplified partial diagram, the three visible lines surround the cell marked 3 on its top, left, and bottom sides.
The edge shared with the cell marked 0 must remain empty because a zero cannot touch any drawn line.
Therefore, the three remaining edges around the 3 are forced.
The next step is to determine how those line segments continue into the surrounding grid without creating branches or violating other numbers.
This demonstrates the central deduction mechanic: information from one cell restricts the edges of its neighbors.
The diagram is an illustrative example, not a complete Daily Loop solution.
Understanding the Numbers in Daily Loop
| Number | Required Lines | What It Tells You |
|---|---|---|
| 0 | Exactly 0 | All four surrounding edges must be empty. |
| 1 | Exactly 1 | One surrounding edge belongs to the loop. |
| 2 | Exactly 2 | Two surrounding edges belong to the loop. |
| 3 | Exactly 3 | Three surrounding edges belong to the loop. |
| Blank | Not specified | Use surrounding clues and loop continuity. |
Zero Cells
Zeros are among the most useful starting clues because they immediately eliminate four possible line segments.
If a neighboring numbered cell shares an edge with a zero, that edge cannot contribute to its required count.
One Cells
A cell marked 1 allows only one surrounding line.
Once one edge is confirmed as part of the loop, the other three can be excluded.
Two Cells
A cell marked 2 requires exactly two surrounding edges.
Those edges might be opposite one another or adjacent, forming part of a straight section or corner of the loop.
Once two surrounding lines have been confirmed, the other two edges must remain empty.
Three Cells
A cell marked 3 requires three surrounding edges.
If one edge is known to be empty, all three remaining edges must be drawn.
If three edges are already drawn, the fourth must be excluded.
Daily Loop Puzzle Sizes and Difficulty
Daily Loop provides four daily puzzle options with different sizes and difficulty levels.
| Puzzle Option | Grid Size | Relative Challenge |
|---|---|---|
| Small | 5×5 | Beginner-friendly |
| Medium | 7×7 | Moderate |
| Large | 10×10 | Challenging |
| Hard Large | 10×10 | More difficult deductions |
The two larger puzzles share a 10×10 grid size but use different difficulty settings.
5×5: Learn the Rules
The smallest puzzle is a good introduction to Slitherlink logic.
With fewer cells and edges, it is easier to track numbered clues and understand how line segments connect.
7×7: Build Your Deduction Skills
Medium puzzles introduce more possible paths and require a greater number of connected deductions.
You may need to combine several neighboring clues before identifying the next forced line.
10×10: A Bigger Challenge
The larger grids provide more opportunities for misleading partial paths and complicated interactions between clues.
Avoiding premature loops and tracking excluded edges become increasingly important.
Hard 10×10: Advanced Loop Logic
The hardest option uses the same grid dimensions but presents a more demanding puzzle.
It is best suited to players comfortable reasoning about numbered cells, dot connections, and overall loop continuity.
Daily Loop Controls and Features
Drawing Lines
Click or tap a connecting edge between two neighboring dots to draw a black line.
This indicates that the edge should belong to the completed loop.
Marking Empty Edges
Click an edge a second time to place a red X mark.
This tells you that the edge should not be part of the loop.
A third click clears the edge, returning it to its original blank state.
Marking excluded edges is especially important in larger puzzles because it prevents repeatedly reconsidering possibilities that have already been ruled out.
Number Feedback
The game changes the appearance of numbered clues according to the current number of surrounding line segments.
- Black indicates that a clue does not yet have enough lines.
- Green indicates that the correct number of surrounding lines has been drawn.
- Red indicates that too many surrounding lines have been drawn.
A green number means its count is satisfied, but it does not guarantee that those are the correct edges for the final solution.
Error Checking
Daily Loop includes an error-checking option, represented by a question-mark button, that can help identify mistakes in your current drawing.
Undo and Reset
Undo allows you to reverse recent actions, while Reset clears your current drawing so you can start the puzzle again.
Timer and Progress
The game records solving time and gameplay progress in the browser.
After completing a puzzle, you can review your result and attempt another puzzle size or date.
Calendar Selection
Daily Loop includes a calendar feature that allows players to select puzzles from other dates.
This is useful if you miss a daily challenge or want to practice additional boards.
Daily Loop Strategy and Tips
1. Start With Zeros
A zero immediately rules out every surrounding edge.
Mark all four edges around a 0 as empty before doing anything else. These exclusions often force decisions in adjacent cells.
2. Use Confirmed Counts
Whenever a numbered cell already has the required number of lines, mark its remaining edges as empty.
For example, if a 2 already has two drawn sides, the other two sides cannot be part of the loop.
This simple habit produces additional deductions without guessing.
3. Check Every Dot
A valid loop can pass through a dot using exactly two connected edges.
If one line enters a dot, the completed loop must eventually leave through another edge. If two lines already connect at a dot, all remaining edges touching it must stay empty.
Three-way intersections are never allowed.
4. Do Not Close a Small Loop Too Early
One of the most common mistakes is creating a closed circuit before the rest of the puzzle has been solved.
A small loop may satisfy nearby numbers while leaving other required line segments outside it.
Because the solution must be one continuous circuit, those disconnected segments would make the drawing invalid.
Before connecting two open endpoints, check whether the resulting loop would exclude any necessary part of the board.
5. Mark Empty Edges Explicitly
Do not rely entirely on remembering which lines you have eliminated.
Use X marks to record excluded edges. This makes the remaining possibilities easier to see and helps you avoid contradictory placements.
6. Examine Borders and Corners
Edges and corners often have fewer possible ways for a loop to continue.
Combine those restrictions with nearby numbered cells to discover forced turns and excluded segments.
7. Work From Certain Moves
Avoid drawing a line simply because it looks like a plausible route.
Instead, focus on cells where the available information leaves only one possibility.
Deduction becomes more reliable when each new line follows directly from an established rule.
8. Use the Smaller Boards for Practice
The 5×5 and 7×7 puzzles help you recognize recurring Slitherlink patterns without the complexity of a large board.
Once you are comfortable with the basic rules, move to the 10×10 challenges.
Daily Loop vs Sudoku and Nonograms
Daily Loop belongs to the same broad family of deduction-based puzzles as Sudoku and Nonograms, but its objective is different.
| Feature | Daily Loop | Sudoku | Nonograms |
|---|---|---|---|
| Main objective | Draw one closed loop | Fill a number grid | Reveal a hidden picture |
| Main clues | Numbers inside cells | Existing grid numbers | Row and column counts |
| Main action | Draw or exclude edges | Place numbers | Fill or exclude cells |
| Key restriction | One unbroken circuit | Unique values in groups | Match all run lengths |
| Main skill | Spatial and logical deduction | Numerical deduction | Pattern deduction |
Daily Loop is particularly appealing to players who enjoy visual logic rather than word or arithmetic challenges.
The numbers serve as constraints, not calculations. No advanced mathematical knowledge is required.
