You're a sensible person, right? So that means you drink tea. Or, at a push, coffee. How many sugars do you take? Oh really? That's interesting. Those of you who gave an answer greater than zero, how many grains do you think that number of spoonfuls would consist of?
Essentially, what I want to know is, would you put 100 grains of sugar into a cup?
Sugar, Sugar is a game that will task you to do just that; put 100 grains of sugar into a cup. Simple. I mean, you'll face the same challenges you would if you were making a cuppa at home: transport the sugar from where it is kept to wherever the cup may be, make sure you're putting the right type of sugar in the right cup, etc. Obviously, just like at home, you'll also need to drop the sugar through a hole in the floor so that it will fall from the ceiling and sometimes you'll need to flip gravity on its head.
Basically, you've been training for this your whole life.
So go. Go and draw those lines necessary to ferry the sugar from the comma it lives in to the waiting cups. Go play Sugar, Sugar.
