Color Reaction
A focused playable challenge that measures Color Reaction.
Keyboard · Mouse · Gamepad
Measure reaction, accuracy, tracking, spatial judgment, and multitasking with keyboard, mouse, or gamepad.
Reaction, aim, tracking, minimap, hand speed, typing, and time perception each have a standalone test and board.

Keep three targets alive at randomized positions across a 180-degree 3D range. A hit replaces only that target while the others remain fixed.
Four targets stay distributed across randomized positions in a 180-degree 3D range. Each hit replaces only the cleared target.
Keep the crosshair attached to a fast, direction-changing drone inside a 180-degree 3D range, scoring coverage and average deviation over time.
Quickly find and switch to the highlighted target among multiple targets.
Read a live tactical scene and identify exposed or covered contacts, faction uniforms, and the neutral tracer-fire corridor.
Read the minion's live health, your attack damage, and incoming allied projectiles to secure the last hit.
Read the enemy's current position, movement vector, and skill flight path to choose an intercept point.
Read Q/W/E/R cooldown numbers and radial masks, then recall which ability becomes ready first.
Compress multiple enemy pings from a tactical minimap, then recall the sector with the highest pressure.
Rotate through three distinct teamfight drills: eliminate the lowest-health enemy, focus a called role, or protect the ally under dive threat.
Alternate between acquiring a moving target and pressing the highlighted Q/W/E/R command during a four-second APM burst.
Execute randomized 8–16 input combos built from directions, light attacks, and heavy attacks.
Read quick slashes, heavy wind-ups, and feints, then parry inside a shrinking 140–260ms impact window.
Follow a steady beat and input when the judgment line enters the window.
The beat speeds up or slows down each time; keep correcting your input phase.
Cues alternate between the left and right tracks; choose the currently lit track.
Read a continuous four-direction chart to test directional recognition, coordination, and resistance to accidental chords.
Search a newly shuffled 4×4 Schulte grid for the requested number.
Resolve Stroop interference by reporting the ink color while ignoring the written color word.
Hold and guide a control marker through a newly generated track without leaving the corridor.
Match a randomly assigned two-to-five-second interval while a live stopwatch provides an objective timing reference.
Maintain central fixation while detecting a 260 ms flash at one edge of the display.
Judge whether a binaural pulse came from the front, back, left, or right.
Balance the circle, distance, and risk to choose the route with the best survival value.
Observe a continuous spell stream and decide whether the current symbol matches the previous trial.
Memorize a randomized number that grows longer by block, then recover it from similar options.
Solve randomized game-like damage, gold, and cooldown arithmetic under time pressure.
Count one requested unit type among mixed shapes whose positions and rotations change every round.
Click the energy core continuously for five seconds while CPS, input cadence, and late-window retention update live.
Strike the physical spacebar for eight seconds to measure burst SPS, sustained pace, and fatigue.
Scroll in either direction for ten seconds to measure total distance, pixels per second, and direction stability.
Type a full tactical callout while the test measures WPM, accuracy, backspaces, and per-key cadence.
Type A through Z in order to measure total completion time, key errors, and key-to-key switching speed.
Read the gap in a fast-moving Landolt C as the target becomes smaller and changes direction.
Memorize three highlighted drones, track them through a moving eight-object swarm, then recover all originals.
Connect a newly randomized node field by alternating numbers and letters in the sequence 1–A–2–B.
Intercept an evasive target that accelerates away from the pointer and changes course near arena edges.
Respond immediately to green GO gates while fully withholding input on randomly mixed red NO-GO gates.
Keep a cursor inside a moving safe zone while independently pressing Space only when an even number appears.
Move a physical cart left and right to keep an unstable inverted pendulum inside the upright zone.
Survive an arena where projectiles enter continuously from all four edges at changing angles.
Predict the landing point of an accelerating energy ball and return it with a horizontal paddle.
Start a precise stopwatch whose readout disappears after three seconds, then stop it at exactly 10.000 seconds.
Compare a real 3D polycube reference with four independently rotated candidates and select the two true rotations rather than mirrored decoys.
Observe a four-panel light-and-tone sequence, reproduce it exactly, and continue as one new item is added each round.
Two particle fields flash for 800–210 ms with randomized dot sizes and positions, then disappear before you choose which side held more.
Report only the center arrow direction while congruent and incongruent flankers create measurable response conflict.
Memorize an expanding set of numbered spatial nodes; after tapping 1, all remaining labels vanish while their positions stay active.
Enter a randomized silent interval and respond only when a short audio cue is actually heard; early inputs are recorded as false starts.
Judge adaptive 8–20 kHz tones mixed with silent catch trials to estimate the highest frequency you can detect reliably on the current setup.
Find one subtly different tile as the randomized color grid expands and its lightness difference becomes progressively smaller.
Estimate the angle between two randomly oriented rays with a 1–179° slider while absolute degree error is recorded.
Draw one freehand closed circle with no guide; best-fit radius, radial deviation, closure, coverage, and path efficiency are measured.
