Type the line while a live keyboard map heats up on the keys you miss, then drills them until you master them.

How to play
Type each target line accurately. A keyboard heatmap glows red on the keys you fumble and cools to blue as you improve. Every new drill is generated to attack your hottest keys, and the run ends when the whole map is charted, every key mastered.
Type the target line; it only advances on the correct key
Watch the heatmap mark your weak keys in real time
Each drill regenerates to target the keys you keep missing
Master every key to chart the full map and finish the run
Controls
Desktop: just start typing; Backspace steps back a character
Phone & tablet: a physical keyboard is recommended, this drill is built around real key presses
Tips & strategy
Prioritise accuracy over raw speed, clean keystrokes cool the map faster than rushing
Don't fight the cursor; let your fingers find a rhythm on the hard keys it keeps serving you
Daily gives everyone the same drill seed; Practice resets a fresh map any time
