step right up
Sixty seconds. Hit the moles, leave the tortoises alone.
Not everything that comes up is a mole. A tortoise costs you five and a second of your time, and there is no way to take a swing back. They come up more often the better you are doing, which is the fairground’s oldest trick and it is being played on you here too.
The moles do not appear at random intervals for long. Every ten points the game tightens: they stay up for less time and the gap between them shortens, down to a floor it will not go below. A round is always sixty seconds, so the score is a fair comparison with your own earlier rounds — which is the only comparison this page offers.
