Color Memory Game Guide & Sequential Visual Working Memory
A color sequence memory game, also known as a Simon game, flashes colors in a pattern that you then repeat in the same order. In this free online version the sequence grows when you succeed and shortens after a miss, so it finds the longest color sequence you can hold in visual working memory.
The architectural limits of human short-term memory have been thoroughly mapped across decades of cognitive psychology. While George A. Miller (1956) identified the informational bottleneck of $7 \pm 2$ items in verbal rehearsal, seminal work by Nelson Cowan (2001) and Steven J. Luck & Edward K. Vogel (1997) revealed that pure visual working memory capacity is strictly constrained to approximately 4 distinct items. Without structured re-coding strategies, unassisted human recall rapidly collapses beyond four sequential elements.
According to Alan Baddeley's multi-component model of working memory (Baddeley & Hitch, 1974; Baddeley, 2000), retaining sequential visual arrays engages the Visuospatial Sketchpad (VSSP). Robert H. Logie (1995) further divided the VSSP into the visual cache (which stores passive chromatic representations) and the inner scribe (which actively rehearses spatial-temporal sequences). Advanced performers systematically recruit the phonological loop to create dual-coded representations, effectively doubling buffer capacity.
With high-precision millisecond chronometry (Woods et al., 2015), this drill measures both sequence span and input latency, providing an accurate benchmark of working memory integrity, processing speed, and mental stamina under time pressure.
How this is measured: every event is timestamped with the browser's performance.now() high-resolution clock, entirely on your device -- no score is uploaded. Browser timers are deliberately coarsened as a Spectre mitigation (typically to about 1 ms), and your display quantizes each change to its refresh interval, about 16.7 ms per frame at 60 Hz (Woods et al., 2015). Treat differences smaller than about 5 ms as measurement noise, and compare your own runs on the same hardware rather than against someone else's setup.
Data transparency: SkillDrills collects no aggregate data. Your scores and settings live only in your browser's localStorage and are never uploaded, so this site publishes no user averages, percentiles or player counts. Every figure quoted here comes from the published work in the References panel below.
This drill is a free browser game for practice and interest. It is not a medical device, a diagnostic instrument, or a screening or treatment tool for any condition, and no score here says anything about your health or your memory in a clinical sense. If you have concerns about your memory or thinking, speak to a qualified clinician.
Scope note: this is browser-based visual-motion practice. It does not record eye position, diagnose an eye or neurological condition, or replace clinician-directed vision therapy. Stop for pain, dizziness, nausea, persistent blur, double vision, headache, or unusual visual symptoms.
