Web Paint-by-Number (webpbn.com) is a logic-puzzle site where you solve grid puzzles by filling cells according to number clues. To find puzzles, start at the site's homepage and look for its puzzle list or solving interface; then use the puzzle's size and difficulty labels to decide what to open. The site's own description is simply "Logic puzzle," and the available site information does not detail account, payment, or download features, so check the live pages for those specifics.

What the site is for

Web Paint-by-Number hosts paint-by-number logic puzzles, also called nonograms or grid puzzles. Each row and column carries number clues that tell you how many consecutive filled cells appear in that line. The site's listed description is only "Logic puzzle," so treat the homepage as the starting point and confirm current features there.

Finding the puzzle list

1. Open webpbn.com in a browser.
2. From the homepage, follow the link or menu item that leads to the puzzle list or the solving area.
3. If a puzzle list appears, scan the entries for size and difficulty labels before opening one.
4. Open a puzzle to reach its solving grid, then read the row and column clues before filling any cells.

Expected result: you land on a puzzle grid with number clues along the top and left edges. If the homepage does not show a list directly, look for navigation links such as puzzles, browse, or solve.

Choosing a puzzle that fits you

Use the same two signals when comparing puzzles:

If a puzzle has no visible difficulty label, judge it by size first: a small grid is usually a gentler start than a large one. The site information provided does not describe a formal difficulty scale, so rely on whatever labels the live pages display.

Solving basics to expect

• Numbers in a row or column describe runs of filled cells, in order, with at least one empty cell between separate runs.
• Compare row clues with column clues to find cells that must be filled or must stay empty.
• Mark confirmed empty cells so you do not revisit them.

For a first attempt, pick a small puzzle and work one line at a time until the pattern becomes clear.

What to verify on the site

The available site information does not mention accounts, pricing, or downloads. Before relying on any of these, check the actual pages on webpbn.com for current options and any access requirements.

To solve a puzzle on Web Paint-by-Number (webpbn.com), read each row and column clue as a list of filled-block lengths in order, then use overlap and elimination to mark cells that must be filled or must be empty. Start with the longest clues and the most constrained lines. You can finish a puzzle using logic alone—no guessing is required—if you work systematically and record what each line rules out.

What the numbers mean

Each clue is a sequence of numbers, and each number is the length of one continuous run of filled cells in that row or column. The runs appear in the same order as the numbers, and at least one empty cell separates consecutive runs.

• A clue of 3 means one run of three filled cells somewhere in that line.
• A clue of 1 2 means a single filled cell, then a gap, then two filled cells, in that order.
• A blank clue (no numbers) means the entire line is empty.

The order matters: 2 1 and 1 2 describe different arrangements, so you cannot reorder runs.

Use overlap to find cells that must be filled

The fastest early progress comes from lines where the clue is long relative to the line length. If the total of a clue plus its mandatory gaps is more than half the line, some cells are forced.

For a line of length 10 with clue 6: the run can start anywhere from position 1 to position 5. In every possible placement, positions 5 and 6 are filled. Mark those two cells, then extend from them.

For a line of length 10 with clue 4 4: the two runs plus one gap total 9 cells, leaving only 1 cell of slack. The first run must start at position 1 or 2, and the second must end at position 9 or 10, so the middle cells are forced empty and the outer cells are forced filled. Work out the minimum and maximum start position for each run; cells covered by every placement are filled.

Use elimination to mark cells that must be empty

Once a cell is confirmed filled, the cells immediately around it are constrained:

• A filled cell at the end of a run has an empty cell on the outer side (unless the run touches the border).
• If a run of length n is confirmed, the cell just beyond each end is empty.
• If a line's filled cells already account for all its clue numbers, every remaining cell in that line is empty.

Mark empty cells explicitly. On Web Paint-by-Number you can mark cells as empty (often with a different mark or color) so you do not reconsider them. Tracking both states—filled and known-empty—is what makes later lines solvable.

Work from the most constrained lines

Choose the next line by how much information it gives you, not by reading order:

1. Lines whose clue total plus gaps nearly equals the line length.
2. Lines with a single large number.
3. Lines where several cells are already filled or already empty, so the remaining options are few.
4. Lines crossing a row or column you just solved, because the new filled cells constrain them.

After each deduction, recheck the crossing lines. A single confirmed cell can unlock a column that was previously ambiguous.

A worked example

Take a 5×5 grid. Row 1 has clue 5, so all five cells in row 1 are filled. Column 3 now has at least one filled cell from row 1. If column 3's clue is 1, then the rest of column 3 is empty, which tells you row 2 through row 5 in column 3 are empty. Those empty cells then constrain the rows they cross. Each deduction feeds the next; this chain is the normal solving rhythm.

Verify before you finish

Check each completed row and column against its clue: count the runs, confirm their lengths and order, and confirm at least one empty cell between runs. A common error is treating two adjacent runs as one, or placing a run one cell off because a gap was not counted. If a line looks wrong, backtrack to the last cell you were unsure about rather than guessing elsewhere.

Common sticking points

• Forgetting the mandatory gap. When adding clue numbers, add one empty cell between each pair of runs. A clue of 3 3 in a line of length 6 is impossible because it needs 7 cells including the gap.
• Marking filled cells without marking empty ones. Empty marks are deductions too; leaving them unmarked causes repeated rechecking.
• Guessing too early. If a line has multiple valid placements, leave it and solve a more constrained line first. The puzzle is designed to be solvable by logic.
• Ignoring the borders. Runs at the edge of the grid have fewer placements, which often makes them the best starting point.

Once you are comfortable with overlap and elimination, most puzzles on the site become a matter of patience: solve the constrained lines, propagate the results to crossing lines, and verify each line as you complete it.

Web Paint-by-Number (webpbn.com) is an online logic-puzzle site built around nonograms, also called paint-by-number or grid puzzles. You solve each puzzle by using the number clues at the ends of every row and column to decide which cells to fill and which to leave blank; the filled cells eventually form a picture. The site describes itself simply as a "logic puzzle" destination, so expect a puzzle-solving focus rather than a general gaming or social platform.

How the core puzzle works

A nonogram is a grid where each row and column carries one or more numbers. Each number tells you the length of a consecutive run of filled cells in that line, and the runs appear in the same order as the clues. Between two runs there must be at least one blank cell.

The solving loop is straightforward:

1. Read the clues for a row or column and compare them with the grid size.
2. Mark cells you can prove are filled, and cross out cells you can prove are empty.
3. Repeat across rows and columns, using each deduction to unlock the next.
4. Finish when every clue is satisfied and the filled cells reveal the picture.

For example, in a 10-cell row with the clue "6", the middle four cells must be filled no matter where the run starts, because a run of 6 cannot fit entirely in either end without covering those cells. That kind of overlap reasoning is the basic skill the puzzles train.

What you actually do on the site

The name "paint-by-number" points to the output: solving is a process of painting cells until an image emerges. The site's own description frames the activity as a logic puzzle, so the emphasis is on deduction from numeric clues rather than guessing or timed arcade play. Because the available site information does not describe account features, pricing, or download options, treat those as unconfirmed and check the site directly if they matter to you.

Who it suits

• Logic-puzzle newcomers who want a clear rule set: the row-and-column clue system is easy to state and hard to master.
• Commuters and short-break solvers looking for self-contained puzzles that need no setup beyond opening a grid.
• Picture-reveal fans who enjoy watching an image appear as deductions accumulate.

If you prefer puzzles with no numeric reasoning, or you need confirmed offline access and account sync, verify those details on the site before committing.

A practical way to start

Begin with a small grid rather than a large one. Small puzzles let you practice the overlap rule and the "clue equals line length" shortcut (a clue matching the full row length means every cell is filled) without getting lost. Work one line at a time, and re-check a row after each column deduction, since progress in nonograms usually comes from alternating between the two directions. If a puzzle stalls, look for lines where the sum of the clues plus the required gaps equals the line length — those lines can often be solved completely in one pass.

In Web Paint-by-Number (also called nonograms or picross), the numbers on each row and column tell you the lengths of consecutive filled blocks in that line. A single number means one continuous run of filled cells. Multiple numbers mean multiple runs, in that exact order, with at least one empty cell between each run. The numbers never tell you where the runs start—only how long they are and in what sequence.

The Three Core Rules

1. One number = one continuous block

A row labeled "5" on a 10-wide grid means there is exactly one run of 5 filled cells somewhere in that row. The other 5 cells are empty. The run could sit at the far left, the far right, or anywhere between—the puzzle doesn't say yet.

2. Multiple numbers = multiple blocks with gaps

A row labeled "2 3" means: first a run of 2 filled cells, then at least one empty cell, then a run of 3 filled cells. The gap can be one cell or several—anything ≥1 satisfies the rule. The total filled cells in that row is 2 + 3 = 5, but the row must be at least 2 + 1 + 3 = 6 cells wide to fit.

3. Order matches reading direction

For rows, numbers read left to right. For columns, numbers read top to bottom. So "3 1" in a column means the 3-block is above the 1-block—never the reverse.

Worked Example

Take a 10-cell row with the clue "4 2":

• Cells 1–4: a run of 4 ✓
• Cell 5: empty gap ✓
• Cells 6–7: a run of 2 ✓
• Cells 8–10: empty (allowed—trailing empties are always fine)

This satisfies "4 2." So would shifting the whole pattern right by one cell, as long as everything still fits in 10 columns.

Minimum Space and Overlap

A useful mental shortcut: the minimum width a clue needs is the sum of its numbers plus one empty cell between each pair. For "4 2" that's 4 + 1 + 2 = 7. On a 10-wide row you have 3 cells of "slack" to distribute as extra empties before, between, or after the blocks.

When slack is small, blocks are forced into overlapping positions—and overlapping cells are guaranteed filled. For example, a clue of "6" in a 10-wide row: the block can start anywhere from position 1 to position 5. Positions 5 and 6 fall inside every possible placement, so those two cells must be filled. This "overlap trick" is the fastest way to make your first marks.

Common Points of Confusion

• "Does '1 1' mean two adjacent cells?" No. Two separate 1s require at least one empty cell between them, so "1 1" needs a minimum of 3 cells and always has a gap.
• "Can a gap be more than one cell?" Yes. The rule is at least one empty cell, never exactly one.
• "Do the numbers include the gaps?" No. Numbers count only filled cells; gaps are never counted.
• "Can a block touch the edge?" Yes. Blocks may start at cell 1 or end at the last cell—edges impose no extra spacing.

How to Use This While Solving

1. Read each row and column clue and compute its minimum width.
2. Compare minimum width to the grid size to find slack.
3. Mark cells that are forced filled by overlap; mark cells that fall outside every possible placement as empty.
4. Cross-check rows against columns—a filled cell must be consistent with both its row clue and its column clue.

Once the numbers click, the rest of the puzzle is pure deduction: each mark you make narrows where the remaining blocks can go.
