I typed ‘sleeping sheep’ into Google to see what would pop up.
I found a game called ‘Sheep Dash’ on a BBC website. It tests your reaction time to tranquillising the fleeing sheep. If you hit them, they go to sleep. It then gives you a result. I didn’t fare too well. Apart from a woeful speed statistic of 0.87 seconds average speed response time, I was given the badge “sluggish snail”.
Let me know how you fared?
