The Find the Mistake Game guide is straightforward: inspect the 12 visible details on each fixed board, choose the one detail that breaks the rule printed above it, and repeat across five boards to earn exactly 1,000 points. Every round is a four-column by three-row grid with 11 details that follow one stated normal rule and exactly one that violates it. The reliable method is therefore a repeatable process of reading the rule, comparing the named property, and checking every tile before committing. You can select a tile directly with a pointer or touch. With a keyboard, focus the board, move the dashed scanner with the Arrow keys, and press Enter or Space on the current cell. A correct tile adds 200 points and immediately opens the next authored board. An ordinary tile creates a repairable miss on the first distinct wrong choice in that round, but choosing a second different ordinary tile ends the run in deadlock. Repeating that same wrong tile does not create a second distinct miss. The five fixtures, anomaly positions, rules, and scoring are deterministic, so this guide explains both a clean completion and the precise consequences of a miss.

The five rule types you will inspect
The route uses five original, code-drawn fixtures rather than a changing image set. Every board is a four-column by three-row grid, but the visual object and the property being tested change from round to round. An arrow direction should not be assumed on a board about bars, dots, spokes, or stripes.
| Round | Fixture | Property to inspect | Rule-first check |
|---|---|---|---|
| 1 | Signal Yard | Arrow direction | Every signal should point northeast. |
| 2 | Dot Registry | Number of dots | Each circular badge should contain three dots. |
| 3 | Gate Ledger | Number of horizontal bars | Compare each bar count with the normal count printed for that round. |
| 4 | Wheel Workshop | Number of spokes | Compare each spoke count with the normal count printed for that round. |
| 5 | Flag Archive | Diagonal stripe direction | Each stripe should rise from left to right. |
Use this table to identify the normal property before scanning. The anomaly is always visible through the property named by the current rule. No board depends on color alone, external knowledge, a trick question, hidden animation, or an unstated convention.
Complete one board in a fixed order
Follow this sequence for each of the five rounds:
- Open the Find the Mistake Game and read the complete rule printed above the board before inspecting any tile.
- Translate the rule into one normal value. For a direction board, identify the required orientation; for a counting board, identify the exact number stated in the rule.
- Scan all 12 details in a consistent order, such as left to right across each row. Do not stop after checking only the first row or the most visually noticeable objects.
- Compare every detail using the named property. The correct candidate is the single detail whose direction, count, or stripe orientation differs from the other eleven.
- Select that candidate directly on the canvas, or move the keyboard scanner onto it and press Enter or Space.
- Read the feedback. A correct choice advances immediately. A first distinct wrong cell produces a repairable miss; repeating it does not create another error, but selecting a second different normal cell causes deadlock.
- Begin the next board after a correct selection and repeat the same read-compare-select process until all five rounds are complete.
Do not carry a normal value from the previous fixture into the next round. The object and the relevant property both change, while the core requirement stays constant: locate the one visible detail that violates the current printed rule.
Control the canvas with pointer, touch, or keyboard
Pointer and touch users can select a visible cell directly. Keyboard users receive a dashed scanner that moves through the same logical four-by-three grid. Both input routes ultimately use the same cell-selection logic, so they produce the same correct result or wrong-cell signature.
| Input route | How to scan | How to submit |
|---|---|---|
| Pointer or touch | Target the desired visible tile on the canvas. | Select that tile directly. |
| Keyboard | Focus the board and use the Arrow keys to move the dashed scanner. | Press Enter or Space on the current cell. |
The visible canvas position is converted into the same logical grid cell used by keyboard navigation. This mapping remains deterministic at the far edge and at exact row or column boundaries. The artwork is rendered on one responsive canvas, and all four equal columns remain inside the container at a narrow mobile width. Each visible cell also remains comfortably larger than a 44-pixel touch target.
Follow scanner and status feedback
The scanner’s accessible label describes the current tile’s public visual property, such as its direction or count. Only the currently scanned cell is described during keyboard navigation, keeping the selection tied to the visible board rather than an unseen answer element.
The status area reports the current board number and the number of distinct misses. An aria-live message explains a correct selection, a repairable miss, completion, or deadlock. Initial page loading does not move focus, but completion or deadlock moves focus to the terminal status. System-modified shortcuts are ignored, repeated keydown events cannot submit multiple selections, and controls use visible focus styling.
Manage score, repairable misses, and deadlock
Each correct selection awards exactly 200 points and advances immediately. The complete five-board score is 200 × 5 = 1,000. There are no random layouts or variable point awards to account for.
A normal tile counts as a wrong selection. The first distinct wrong cell in a round is repairable because the miss is signed by both the current round and the logical cell. Selecting that same cell again does not consume another error. However, selecting a second different normal cell closes the run in deadlock. If you find the anomaly after one repairable miss, the game advances normally and clears that round’s error as part of moving forward.
Completion and deadlock are terminal. Later pointer selections, keyboard selections, cursor movements, or invalid coordinates cannot change the score, round, feedback, or error history. The interface retains a local best-score display and a Restart control, but the result is recreational: it only records play against these five fixed boards under their printed rules and does not measure vision, attention, intelligence, learning, work, or health.
Restart from the exact initial state
The fixtures are deterministic. There is no shuffled layout, random anomaly, daily challenge, network response, or adaptive difficulty. Restart returns the run to the exact initial value: the first board, the first scanner cell, zero score, no errors, and no terminal flag. The next attempt therefore presents the same five rules, layouts, and anomaly positions in the same order.
Everything runs locally in the browser. Selections are not sent to a server, no image is uploaded, and the game requests no hardware permission or paid service. This fixed local route makes pointer, touch, and keyboard results reproducible without relying on outside clues.
Use a compact full-run checklist
- Read the complete rule above the current board.
- Name the one property being tested.
- Establish the normal direction or count before scanning.
- Compare all 12 details rather than judging from color alone.
- Confirm that the candidate differs from the other 11 details.
- After one miss, avoid selecting a second different normal cell.
- Complete all five correct selections to finish on 1,000 points.
This is the full Find the Mistake Game method: printed rule first, complete comparison second, one verified selection third. Keeping those stages separate makes the fixed route easier to audit and keeps scoring, repairable errors, deadlock, restart, and terminal behavior predictable.
