The bottle-cap games.
Learn to sort, find out what your caps are worth and challenge your family. Every game teaches a rule that helps my parents.
What are your caps worth?
Tell me how many caps you collect each week. I do the maths with the real rates Resialentejo and Amorim pay.
Approximate maths: a plastic cap or a metal cap weighs about 2 g and a stopper about 4 g. Plastic at €411.60/t, metal caps at €465.60/t, cork at €500/t. A month of treatment costs €6,740.
Cap or not?
Ten statements, true or false. Answer quickly: at the end I show you the rules that caught you out.
