"In twenty one"You say.
"Your goal is to score 21 points,
if you have more then you will lose,
you can and do not dial 21 and stop when you seem that you have enough,
but if someone has more than you then you lose.
Oh yes, ace = 10, king = 5, lady = 4, jack = 3,
and the remaining cards are equal to the value indicated on them,
for example 5 peaks = 5. Well, begin!"
