Train at your pace or compete globally.
Structured difficulty rulesets and customizable time intervals paired with a full ranked progression ladder, monthly speedruns, and over 100 unlockable badges.
Casual
Relaxed flow for warming up and building muscle memory on new syntax without penalties.
Medium
Balanced competitive pressure that rewards clean accuracy while maintaining high speed.
Hardcore
Sudden-death precision. A single mistyped character immediately ends the sprint.
Custom Timer
Every snippet features an adjustable timer—pick a challenging 15-second sprint or a more casual 5-minute session to match your pace.
Type Points (TP) & 10 Tiers
Earn TP after every completed sprint to climb from Newbie Typer to Grandmaster Typer.
5-Minute Global Speedrun
Compete on a featured monthly snippet with 3 weekly attempts and permanent Top 5 profile medals.
100+ Steam-Style Badges
Unlock achievements for speed records, daily streaks, flawless runs, and polyglot mastery.
Deep biomechanics and keystroke telemetry.
Analyze your typing mechanics second-by-second. Track speed evolution curves, 10-finger load distribution, problem bigrams, and daily consistency streaks.
10-Finger Biomechanics
Inspect workload across both hands and all ten fingers. Spot pinky fatigue on symbols and balance your bilateral typing posture.
Keystroke Replays & Bigrams
Replay your sprint keystroke-by-keystroke at up to 4x speed. Pinpoint the exact symbol pairs (`=>`, `!==`, ``) that cause hesitation.
Speed & Accuracy Evolution
Track your net WPM velocity trends, historical growth charts, and burst cadence across your last 10, 25, 50, or all completed runs.
Speed & Accuracy Evolution Curve
Historical WPM velocity & consistency over time
GitHub-Style Activity Matrix
Track your daily history & consistency over time
