How to play
The bowler runs in after a random pause, so you can't just tap to a rhythm. Watch the ball out of the hand, see where it bounces, and swing (tap anywhere on the pitch, or press Space) at the exact moment it arrives in the glowing ring in front of your stumps. You get one swing per ball. Each delivery is quicker than the last, so the final ball of the over is the hardest.
Your score is shown the cricket way, runs for wickets: 26/1 means 26 runs and one wicket. A perfect over is 36/0.
Timing is not the same as reaction speed
The reaction time test asks how fast you can respond to something appearing. Batting asks something else: can you predict when the ball will arrive and be there at that instant? A ball bowled at 150 km/h reaches the batter in roughly half a second, which is too little time to see, decide and swing from scratch. Real batters get away with it by reading the delivery early and committing to a prediction.
That is exactly what this game trains. If your average comes back early, you are guessing; if it comes back late, you are waiting too long to commit. There's more on the research, including eye-tracking studies of some of the world's best batters, in how batters hit a 150 km/h delivery.
