Advanced typing practice
Advanced typing drills with dense, symbol-heavy production code. Dense, generic-heavy, symbol-saturated code. Maximum keyboard chaos.
Every keystroke counts toward your WPM, accuracy and consistency. After each run, the heatmap highlights the exact keys to drill next — so your practice always targets your real weaknesses.
