Seven-segment digit maps
Digits 0-9 are represented by standard seven-segment bars. The solver tests every character that can result from removing and adding one or two bars.
Free Online Matchstick Puzzle Solver
Matchstick and Seven-Segment Puzzle Solver for one-match and two-match moves.
Enter a matchstick puzzle made from digits, arithmetic operators, equality signs, or Roman numerals. Choose whether to move one or two matches, control which symbols may change, and enumerate valid expressions or visual shape results entirely in your browser.
Move matches across digits, operators, equals, and Roman numerals
Pick a mode, enter the puzzle text, then run the local enumerator. The solver compares built-in match segment maps, lists every allowed remove/place pattern, and verifies equations without using OCR, APIs, databases, or a backend.
Puzzle input
Runs locally
The tool uses built-in segment maps for seven-segment digits, arithmetic symbols, equality signs, and I/V/X Roman numerals. It does not upload puzzle text or call an external solver.

Scope boundaries
- This page is deliberately named Matchstick and Seven-Segment Puzzle Solver, not Matchstick Equation Solver, so it is not confused with SolverBox's ordinary Equation Solver.
- It does not perform OCR, recognize handwritten matchstick photos, read screenshots, scrape social posts, provide a daily puzzle feed, or maintain a puzzle database.
- It is intended for compact typed puzzles using the supported symbols and local expression validation.

How the Matchstick and Seven-Segment Puzzle Solver works
The solver is a pure frontend enumerator built for compact typed matchstick puzzles, not image recognition.
Operator and equals transformations
Arithmetic symbols and equality signs use their own match maps, so puzzles can allow operator changes, forbid them, or decide whether the equals sign may participate.
Roman numeral matchsticks
Roman I, V, and X are mapped as simple match shapes. Roman tokens can be transformed visually and, when an equation is present, evaluated as Roman values.
Matchstick puzzle input guide
Use these rules to keep the typed puzzle precise and the browser enumeration useful.
01
Choose the symbol family
Use Seven-Segment Digits for digital 0-9 bar puzzles, Operator Transformation when the arithmetic signs are central, and Roman Numeral Matchsticks for I/V/X match shapes.
- Use × or * for multiplication
- Use ÷ or / for division
- Use capital I, V, and X for Roman numerals
02
Set the movement rules
Choose one-match or two-match search, then decide whether digit matches, operator matches, and equals-sign matches may be removed or placed.
- Turn off operator changes for digit-only puzzles
- Leave relocation on for classic move-a-match riddles
03
Read every feasible answer
Each answer shows the before and after expression, highlighted changed characters, removed matches, placed matches, and whether the equation was verified or only a visual result.
If a riddle expects exactly one solution, tighten the rule checkboxes before comparing answers.
Matchstick and Seven-Segment Puzzle Solver FAQ
Common questions about modes, move rules, equation validation, and the tool's no-OCR boundary.
Is this the same as a Matchstick Equation Solver?
No. SolverBox already has an Equation Solver for ordinary algebra. This page is specifically for matchstick and seven-segment puzzle transformations, including digit bars, operator symbols, equals signs, and Roman numeral shapes.
Can it solve move one matchstick and move two matchsticks puzzles?
Yes. Select Move 1 match or Move 2 matches. With relocation enabled, every moved match must be removed from one allowed segment and placed on another allowed segment.
Does the solver recognize matchstick images?
No. It does not perform OCR, read handwriting, inspect screenshots, or scrape social posts. Type the puzzle using supported symbols so the browser can enumerate segment changes locally.
How are Roman numeral matchstick puzzles checked?
The solver maps I, V, and X to match shapes. If the transformed result contains exactly one equals sign and valid arithmetic, Roman tokens are converted to values for validation; otherwise the result is reported as a visual transformation.
