Key Rally
Type 8 English targets accurately. Three misses or the clock ending finishes the round; device-local weak keys are prioritized.
The timer starts with the round. A complete target is checked automatically.
Understand your game result
Complete-target hit rate = successful targets divided by total submissions (successful targets plus misses). A one-character error counts as a missed target; the game does not calculate character accuracy or WPM.
Scores, lesson progress, and weak-key practice stay on this device. There is no public ranking, certificate, or recruitment assessment.
