Whack the moles before they duck
Moles pop up at random holes for a brief moment before ducking back down — tap them before they disappear. You've got 30 seconds on the clock to whack as many as you can.
It rewards quick, loose attention rather than careful thinking — a good match for when you want to burn off restless energy in half a minute rather than sit still. The moles speed up and slow down unpredictably, so staying loosely alert works better than trying to anticipate a pattern. Your best score is saved.
