Every round of Mirror Image Quiz ends with a single correct reflection: a point at x, y must map to 100 minus x, y while the y coordinate stays unchanged, and the candidate that satisfies that rule for all six source points earns exactly 200 points. The quiz runs five original rounds in sequence, so a perfect run produces the fixed 1,000-point finish stated on the puzzle page, and the same coordinate rule decides every round regardless of which asymmetric six-point shape appears on the left side of the mirror line. Because production stores only the source points and four literal option arrays, with no semantic label and no stored correct index, the only way to identify the right option is to apply the reflection yourself. This article walks through the exact rule, the round layout, the mistake rules, and the controls so anyone can work through all five rounds with confidence on the Mirror Image Quiz page.
What the Mirror Image Quiz Shows on Screen
Each round presents the same compact layout. On the left half of the board sits a single asymmetric six-point polygon drawn in the foreground outline, with its first point flagged by a visible orientation marker so the polygon reads in the right order from the first edge onward. A dashed vertical line sits near the middle of the 100 by 100 product coordinate space; that dashed line is the mirror, not the outline of either polygon, and it stays clearly distinct throughout play. Below the source polygon the interface shows a two-by-two option grid with four literal candidate shapes labeled A through D, each rendered from its own stored point array rather than from CSS styling alone. Every candidate uses the same orientation marker on its first point, and the SVGs inherit the site's foreground, accent, surface, and border color tokens so the visual differences between options come from the geometry rather than from decoration.
The round never reveals which option is correct before a choice is made. There is no stored correct index, no semantic transform name printed beside any option, and no ARIA description, hidden text, or status element that names the answer. The only information available to every player is the visible coordinate geometry of the source polygon and the dashed vertical mirror line, and comparing that geometry against each candidate's six points is what the next section describes.
The Reflection Rule That Decides Each Round
The mirror is the vertical axis, so the rule is purely about the x coordinate. For every source point at x, y, the correct reflection lives at 100 minus x, y. The y coordinate never changes because the mirror runs vertically; only the horizontal distance to the line flips, and the new distance is measured from the opposite side. Points that start on the mirror stay on the mirror, points that sit one unit to the left land one unit to the right, and a point on the far left edge at x 0 lands on the far right edge at x 100. The same rule applies to all six points in order, so the polygon as a whole maps to its mirror twin while keeping its height, its turn sequence, and its orientation marker.
| Source point (x, y) | Reflected point (x, y) | Rule applied |
|---|---|---|
| (10, 18) | (90, 18) | x becomes 100 − 10; y unchanged at 18 |
| (36, 24) | (64, 24) | x becomes 100 − 36; y unchanged at 24 |
| (0, y) | (100, y) | boundary point swaps to the far opposite side |
| (100, y) | (0, y) | boundary point swaps to the far opposite side |
That single rule is enough to decide every option, because the four candidates are literal coordinate arrays rather than transformed copies of the source. One of them is the generated reflection; the others are deliberately different arrays that share some, but not all, of the reflected points. Matching every point in order is what produces a correct answer, and matching only some points is what produces a wrong one.
Play Mirror Image Quiz Round by Round
The round flow is short and repeats five times. Working through it step by step keeps the reflection rule and the option grid easy to manage.
- Inspect the source polygon. Read the six points from the orientation marker onward and note where each point sits relative to the dashed vertical mirror line.
- Generate the reflection mentally. Replace every x with 100 minus x and keep every y exactly the same; picture the six resulting points in order.
- Compare the four options. Look at option A in the upper left, B in the upper right, C in the lower left, and D in the lower right, and find the candidate whose six points match the reflected set in order.
- Confirm the choice. Press Enter or Space on the focused option, or click or tap it directly; the game advances on a correct pick and adds 200 points.
- Move to the next shape. A correct answer clears any failure signature and presents the next original six-point polygon, while Restart returns the run to the first polygon at any point.
The same flow handles mistakes gracefully. If the first pick is wrong, the game records the round and option position as a normalized failure signature and shows a neutral correction prompt while leaving all four options available, so a corrected choice still earns the full 200 points and advances to the next original shape.
How Scoring and Mistakes Work in Five Rounds
Scoring is fixed and round-based. A correct option always adds 200 points, a corrected choice after one mistake adds the full 200 points, and a perfect run lands on exactly 1,000. The progression is predictable, which means the only thing that changes from run to run is whether the player needed the repair step on any given round.
| Round | Result | Running score |
|---|---|---|
| 1 | Correct | 200 |
| 2 | Correct | 400 |
| 3 | Correct | 600 |
| 4 | Correct | 800 |
| 5 | Correct | 1,000 |
The repair rule is the part that surprises new players. Repeating the same wrong option in a round does not count as a second miss; the game deduplicates identical wrong choices. Choosing a second, different wrong option in the same round deadlocks the run, the board freezes, and Restart is the only way back to the first polygon. Because every score is built from choices on five fixed recreational shapes, comparing scores across people is not informative, and a single 1,000-point run carries the same weight as any other.
Keyboard and Pointer Controls for the Option Grid
Keyboard control stays scoped to the four options. Focusing any candidate makes it the logical cursor, and the roving focus ring follows the same option as the cursor so what is highlighted and what Enter or Space activates always match. Left and Right move within a row, while Up and Down move between the two rows, and repeated keydown events are ignored so a held arrow does not whip through the grid. The page installs no global arrow, Enter, or Space listener, which means Restart and unrelated browser shortcuts keep their native behavior.
Pointer and touch players can use the option buttons directly without any keyboard step. Each option button is taller than the 44-pixel minimum touch target, the gaps stay small, and the entire grid fits inside a 390-pixel viewport, so two-thumb or single-finger selection works on a phone. Players who enjoy this style of five-round, exact-score puzzle may also like the pacing of How to Play Binary Decoder Game: 5 Rounds to 1,000 Points, which keeps the same five-round 1,000-point finish with a different mental task.
What the Mirror Image Quiz Is Not
It is worth being explicit about what Mirror Image Quiz does not do. It is a recreational visual puzzle built from five fixed, original asymmetric polygons, not a standardized, educational, psychological, or diagnostic assessment. The score reflects choices on those five authored shapes and says nothing about intelligence, spatial reasoning, school readiness, examination performance, vision, neurological status, learning needs, occupational fitness, or any other human trait. Display size, contrast preferences, input method, familiarity with coordinate reflections, and ordinary distraction all affect play without saying anything diagnostic.
All logic runs locally in the browser. Source points, choices, failures, and scores are not uploaded, and if browser storage is available the shared game shell only saves the best completed score on that device. Blocked storage removes that convenience without changing the puzzle, and no account, paid service, network calculation, image upload, camera, sensor, package, or new dependency is required. Restart returns the run to the first polygon, and the shared double-Escape boss screen hides the quiz without changing its round, cursor, failures, or score, so a brief interruption never costs progress.
