Track your mental fitness across nine cognitive domains — with a mastery score that reflects how you actually train.
In short: the Cognitive Skills Report shows a 0–100 mastery bar for each of nine cognitive skills, built from your server-verified game sessions. Scoring rewards consistency, variety and difficulty rather than repetition alone, decays gently when you stop training, and recovers quickly when you return. It measures your training progress on this platform — not your intelligence.
The nine measured skills
Selective Attention — responding to what matters while ignoring competing information; the core demand of the Stroop test.
Inhibitory Control — holding back an impulsive response when the situation demands it.
Cognitive Flexibility — adapting as rules and difficulty shift mid-game.
Processing Speed — how fast you turn perception into a correct response.
Pattern Recognition — spotting the one item that breaks the pattern.
Visual Working Memory — holding visual information in mind while you use it.
Sustained Attention — staying alert and consistent over a continuous run.
Problem Solving — understanding rules and making precise decisions under time pressure.
Reasoning — deducing the right answer from evidence, step by step.
How mastery scoring works
Every valid game session is timed server-side in milliseconds and scored for accuracy and difficulty. Each game feeds specific skills, and your performance in those skills converts into effective training (effective plays): an average session counts as one, a strong session counts for more, a weak one for less.
Mastery for each skill grows from 0 to 100 with consistent training. The first 40 effective plays take you to 70 — early gains come fast — and every 5 effective plays after that add one point, up to 100. For example: 5 effective plays ≈ 15%, 20 ≈ 42%, 40 = 70%, 90 = 80%, and 190 = 100%.
How you train changes how fast you progress:
Streak bonus — playing on 3, 7, 14, or 30 consecutive active days multiplies progress up to ×1.15.
Variety bonus — training the same skill through two or three different games within a week: ×1.05 to ×1.10.
Challenge bonus — high difficulty combined with 80%+ accuracy: ×1.10.
Personal-best bonus — beating your own record: ×1.05.
Anti-farming — repeating the same game more than three times in one day earns progressively less, down to ×0.40.
Consistency is protected in both directions. A skill you stop training loses a few displayed points (−1 after a week, at most −15 after five weeks), but nothing you earned is deleted — your first three valid sessions back restore the lost points in 40/30/30 steps. The dashboard shows your current active mastery; a lifetime mastery accumulates underneath and never decreases.
Only valid, server-verified sessions count. Invalid or flagged sessions earn nothing — so scores cannot be inflated by rapid tapping or automation.
What mastery is — and what it is not
A mastery percentage is your training progress on this platform: how much consistent, varied, verified practice you have invested in that skill. It is not a percentage of your brain, not a medical assessment, and not an IQ score. Whether training transfers beyond the trained tasks is a genuinely debated research question — the report measures what you actually trained, honestly.
Why it helps
See progress instead of guessing — per-skill mastery bars turn "I feel sharper" into numbers that move week over week.
Find your weak spots — a nine-skill profile shows where you are strong and what is undertrained.
Train deliberately — pick the games that load exactly the skills you want to grow.
Build the right habit — streaks, variety bonuses and gentle decay nudge you toward regular, varied practice — the pattern linked to real gains.
Honest by design — every score is server-verified and built only from sessions that pass validity checks.
