Compare the two approaches by applying the same two-part acceptance test: the specimen’s center must be within 4 plot units of the target, and its 45-degree orientation must match exactly.
In Shape Rotation Match, the practical alternatives are pointer-led alignment and keyboard-led alignment. Both manipulate the same asymmetric specimen on the same measured field, so they are two ways to produce a pose rather than two levels with separate tolerances. Before submission, the dashed silhouette is the only target information shown; there is no correct-angle readout, target coordinate pair, or hidden answer to consult.
Set a Common Comparison Standard
A fair comparison should separate the final result, the controls used, and the recovery required. The most important measure is not how quickly a shape looks aligned. It is whether the complete pose passes the game’s position and orientation checks without creating a second distinct rejected pose.
- Outcome: Does the approach produce one combined pose that passes both checks?
- Control: Does it use direct pointer movement, discrete keyboard commands, or a combination?
- Recovery: Can you correct a rejected attempt before the next distinct rejection ends the run?
This standard matters because every round contains a different original polygon with at least six vertices and no mirror symmetry. An incorrect turn cannot look identical to the required pose. Compare visible edges, corners, and overall orientation rather than relying on a rough impression of overlap.
Compare Pointer and Keyboard Routes
The two routes use different input paths but feed the same geometric pose into the same acceptance check.
| Task | Pointer route | Keyboard route |
|---|---|---|
| Translate | Press the solid specimen, move the pointer or finger, and release it near the outline. | Focus the solid specimen and use the Arrow keys for eight-unit position nudges. |
| Rotate | Use the native controls for exact 45-degree counterclockwise or clockwise turns. | Press Q or E for the same 45-degree turns. |
| Submit | Use the Submit button. | Press Enter while the specimen has focus. |
| Accepted result | Center distance at most 4 plot units and exactly matching orientation. | Center distance at most 4 plot units and exactly matching orientation. |
The pointer route provides direct visual repositioning. Its drag is not decorative: captured pointer movement is converted from screen coordinates into the visible 320 by 240 SVG coordinate system before the position changes. Mouse and touch therefore operate on the same visible geometry, including with responsive sizing or browser zoom. The specimen also remains inside a safe plotting boundary, so it cannot be dragged completely beyond the board.
The keyboard route offers more discrete commands. Arrow keys, Q, and E work only when the solid specimen is focused, while the rotation and Submit buttons retain their native keyboard behavior. Because an Arrow-key nudge covers eight units but the center tolerance extends only four units from the target center, treat keyboard nudges as coarse positioning rather than proof of an exact fit. A pointer drag can be useful for final centering. For a control-by-control reference, see the keyboard control reference for Shape Rotation Match.
Align a Specimen in Shape Rotation Match
Use this sequence for each of the game’s five rounds, changing the input method to suit your preferred approach.
- Identify the two shapes. Locate the solid asymmetric specimen and the dashed target silhouette. The solid piece begins away from the target and at a different orientation, so both translation and rotation are required.
- Record a translation. For pointer play, press the solid specimen, drag toward the dashed outline, and release nearby. Pointer movement changes its actual SVG coordinates. Alternatively, focus the specimen and use the corresponding Arrow keys for eight-unit nudges.
- Record a rotation. Use either native rotation control for an exact 45-degree turn in the required direction. Keyboard players can use Q or E while the specimen is focused. Compare a distinctive corner and the surrounding sloped edges after each turn.
- Refine the two properties separately. Rotating changes orientation but does not move the specimen’s center. Moving changes position but does not correct its angle. Adjust whichever property remains wrong, then check the other again.
- Check the complete pose. Confirm that the center is close enough to the target center and that the orientation lands on the exact required 45-degree grid position. The game requires both a recorded move and a recorded rotation.
- Submit once the pose appears correct. Press the Submit button or Enter. If the pose is rejected, adjust it deliberately before trying again, because a second genuinely different rejection closes the run.
- Continue after acceptance. A correct specimen awards 200 points and immediately loads the next authored round. Continue until all five rounds have been cleared or the run reaches a terminal state.
Read the Two-Part Pose Check
Position is measured with Euclidean center distance in the same SVG coordinate system visible on the plotting field. Every round uses the same published tolerance: a center exactly four plot units from the target center is accepted, while a distance of 4.001 is rejected. This is a center-distance check, not a requirement that every edge or vertex overlap perfectly.
Orientation uses shortest circular angle distance, so angles close to zero are compared correctly across the 360-degree boundary. The angular tolerance is zero: any nonzero angular difference is rejected, even when the two outlines appear extremely close. Because every authored target and player rotation uses the same 45-degree grid, the correct turn can be identified by exact orientation rather than by estimating a free-form angle.
Both transformations remain separate throughout the check. That makes the comparison objective but also means a visually persuasive near-match can still fail if the center is outside tolerance or the orientation is off by even one grid step. Neither the pointer route nor the keyboard route receives a more forgiving standard.
Recover from a Rejected Pose
One distinct rejected pose can be repaired. After an incorrect submission, continue moving or rotating the same specimen and submit the corrected pose without losing the round. This makes the first rejection a useful checkpoint: compare the submitted placement with the dashed outline, then change the position or angle that still differs.
Pressing Submit repeatedly with the same current round and rounded submitted pose does not consume a second chance. A genuinely different rejected pose creates the second error and ends the run. Once the first error has been corrected and accepted, the failure ledger is cleared before the next specimen. This rule applies equally to pointer and keyboard play, so deliberate corrections are safer than cycling through several clearly different guesses.
Track the Five-Round Finish
The game contains five rounds, each presenting a different original polygon. Every accepted specimen awards exactly 200 points, and the five-round maximum is exactly 1,000 points. The score is fixed for acceptance rather than based on speed, so a quicker method does not score more than a slower one that reaches the same accepted pose.
Completion and deadlock both freeze translation, rotation, submission, and keyboard actions. Restart always returns the game to the first initial pose with zero score and zero errors. The shared game shell retains only the best local score, so a failed run does not prevent a fresh attempt at the full five-round route.
Choose the Route That Fits the Round
Use the pointer-led route when direct, visually guided positioning is your priority, especially with a mouse or touch input. Use the keyboard-led route when you prefer explicit commands, eight-unit nudges, 45-degree turns, and Enter submission. A hybrid route can combine broad keyboard positioning with a pointer drag for the final center adjustment.
The decisive comparison is not which input method looks more advanced. Both routes use the same asymmetric form, the same visible outline, the same 4-unit position allowance, and the same exact orientation rule. The safer route for a particular session is the one that reaches an accepted pose with fewer distinct rejected attempts. This is also a different task from choosing equivalent pieces in a matching game or rotating fixed tiles: here, one continuous form must be both translated through space and rotated into an exact visible pose.
