SUMMARY OF PLAYS
THE RULES OF PLAY
In its ancient form Morra is a hand game played for points by two people,1
both players show either one or two fingers, and simultaneously call,
out loud, the number of fingers that the other player will show.
A correct call wins the number of points showing as fingers (2, 3, or 4,)
if both players call correctly there is no winner.

Morra is classed as a zero-sum two person game2 by virtue
of what is called the payoff matrix:
If by [1,1] we designate that a player shows one finger and calls
that the other player will show one finger we can construct
the following matrix of points that can be won by a player:
If both players play randomly then they will tend to win the
same number of points during a game, but if one player uses
a strategy the outcome can be weighted.
