A shadow matching game pairs one colored specimen with three solid silhouettes and rewards you with exactly 200 points for each correct outline you identify across five fixed cards. In the Shadow Matching Game, every specimen, silhouette, and option order is built from original SVG paths rendered locally in the browser, so there are no downloaded images, emoji characters, licensed figures, or network calls involved in the run. You compare only the outside contour of the specimen to the outside contour of each silhouette, not the interior coloring, which makes the puzzle a study of outer boundary rather than surface detail. The catalog contains five disclosed original objects — an Orbit lamp, a Fin vase, an Arch chair, a Kite clock, and a Leaf kettle — each authored with a different silhouette so that careful comparison is enough to clear the run.
The five original specimens and their silhouettes
Every round in the Shadow Matching Game uses a card drawn from a fixed catalog of five objects. Each card presents one colored specimen at the top and three solid silhouettes directly below, and the silhouettes are the exact outer path of an object filled with a single tone. Because every shape was authored for this game, the same fixture plays on every reload: there is no random draw, no browser seed, and no previous-score carryover that changes which silhouettes appear on which card.
The Orbit lamp combines a circular shade, a slim stem, and a wide base, producing a profile that reads very differently from the other four objects. The Fin vase has a rounded body with side fins, while the Arch chair uses an arched back, a seat, and visible legs whose outline is unmistakably furniture-shaped. The Kite clock is a diamond case hung from a small stem, and the Leaf kettle pairs a wide body, a spout, and a leaf-shaped lid detail that breaks the otherwise round profile. Because the boundaries differ, the puzzle is solvable by reading only the outer shape of the specimen.
Reading the outer shape rather than internal decoration
The five specimens were chosen so that the outer boundary alone is enough to pick the right silhouette, without leaning on texture, color, or interior pattern. The lamp's circular shade plus base produces a silhouette very different from the chair's arch; the clock's diamond case plus hanging stem is unlike the kettle's spout; and the vase's side fins push its outline sideways in a way no other object matches. This design choice matters because the silhouettes are solid: they preserve only the outside path of the object, not internal lines. A run that tries to match by color or by interior detail will fail to narrow the field, whereas a run that studies each silhouette's contour will resolve every card quickly.
The same principle of outer-shape reasoning appears in other deterministic matching fixtures, including the Matching Shapes Online puzzle, where pairs of original SVG pieces are matched across drag, click, and keyboard paths for an audited 1,000-point finish.
Play Shadow Matching Game step by step
- Open the Shadow Matching Game card and read the colored specimen at the top. Mentally trace its outside boundary and identify the dominant features — for example, a circular shade, a diamond case, or a leaf-shaped lid.
- Look at the three solid silhouettes directly below the specimen. Compare each silhouette's outer contour to the contour of the specimen, ignoring interior lines because the silhouettes are filled with a single tone.
- Pick the silhouette whose outside path matches the specimen's outline. Use a pointer or touch screen to tap the correct silhouette, or move to it with any Arrow key and submit with Enter or Space.
- Wait for the visible feedback. A correct match awards 200 points immediately and advances the catalog to the next fixed specimen, with a progress strip marking the card as completed.
- Repeat the cycle for the remaining cards until the catalog closes. After the fifth correct match, the score reads exactly 1,000 points and the run is frozen.
Scoring rules, mismatches, and the 200-point math
Each correct silhouette awards exactly 200 points, and the catalog has five cards, so a clean run produces 5 × 200 = 1,000 points. This is the only path to a 1,000-point finish, and the formula is written into the run itself rather than scaled by difficulty or streak bonuses. Selecting the wrong silhouette does not immediately end the run; instead, one distinct mismatch on a card is recoverable. Selecting the same wrong silhouette again on the same card is deduplicated and does not spend another error, so a misclick on the same option only counts once. A second different mismatch anywhere in the run, however, closes the catalog until you press Restart, which resets the score to zero, the mismatch count to zero, the cursor to the first choice, and the card back to the first specimen in the fixed order.
This two-error rule keeps the run auditable: any 1,000-point finish must be a sequence of five exact matches with no more than one distinct wrong silhouette across the whole catalog. Unknown silhouette identifiers and invalid cursor movement are treated as strict atomic no-ops, so they neither advance the score nor count as a mismatch, and the terminal score freezes the moment the catalog closes.
Controls, focus, and the 44-pixel target
Shadow Matching Game accepts pointer, touch, and full keyboard play. On pointer and touch screens, a tap on any silhouette submits that choice. On the keyboard, any Arrow key moves the cursor through the three silhouettes in order, and Enter or Space submits the currently focused choice. The current choice carries a visible focus treatment so keyboard players always know which silhouette is selected, and each silhouette button meets the 44-pixel target size, which is the standard minimum tap area for touch accessibility.
The shared game shell adds a Restart control, a best-score storage area, and a double-Escape Boss Key that hides the screen if you need to step away mid-run. A visible progress strip marks completed catalog cards, and the option order on each card is fixed: the correct silhouette appears second for the Orbit lamp, third for the Fin vase, first for the Arch chair, second for the Kite clock, and third for the Leaf kettle. Because the order is deterministic on every restart, you can audit any card by simply reopening it and checking the position of the matching contour.
How Shadow Matching Game compares with other matching puzzles
The Shadow Matching Game sits in a family of deterministic, browser-based matching puzzles, but it differs from photo-based or icon-matching games in several specific ways. The following table summarizes the differences as they are described in the verified product contract, so you can see at a glance what the run actually contains.
| Feature | Shadow Matching Game | Photo or icon matching puzzles |
|---|---|---|
| Object source | Five original SVG specimens authored for the game | Photographs, icons, or emoji drawn from external libraries |
| Silhouette style | Solid outer boundary only, no interior lines | May include internal detail or color hints |
| Options per card | Three solid silhouettes | Often two or four pictures |
| Option order | Fixed and deterministic on every restart | May be shuffled per round or per session |
| Scoring | Exactly 200 points per correct match, 1,000 total | Varies by streak, timer, or level |
| Mismatch handling | One recoverable mismatch, repeat ignored, second different mismatch closes the run | Often deducts points, loses a life, or restarts immediately |
| Network use | All processing stays in the browser | May fetch images or scores from a server |
These contrasts come from the verified contract for Shadow Matching Game and from the typical behavior of photo-based matching puzzles, so the table is descriptive rather than a ranking. The five-card fixed catalog, the deterministic option order, and the 200-point-per-card scoring are the concrete reasons a 1,000-point finish is reproducible rather than lucky.
Restart behavior, terminal freezing, and what the result measures
Because every silhouette and option position is fixed, a clean Shadow Matching Game run looks the same on every device. Restart creates the original first card, the fixed option order, a zero score, a zero mismatch count, and the first-choice cursor, so any prior run's score is fully reset. Independent tests restate all five object labels, card identifiers, option orders, and correct answer positions as literal fixtures, and they verify unique choices within every card, deterministic restart, five 200-point approvals, repeat-error deduplication, two-distinct-error deadlock, illegal input rejection, cursor wrapping, and terminal freezing.
The visible feedback distinguishes five outcomes — a correct match, a first mismatch, a repeated mismatch, completion, and deadlock — so you always know whether the next tap will advance the catalog or close it. Completion and deadlock freeze both matching and navigation, so a terminal score cannot change after the result is shown. The result measures completion of five disclosed fictional specimens only and is entertainment, not a vision examination, developmental screen, accessibility diagnosis, educational placement test, or claim about a player's real-world recognition ability. No personal gameplay history is transmitted or stored, and your best score lives only in your browser.
