Nim Rules - Misre Play
Nim misre play is between two players and played with three heaps of any number of objects (we
will use 3, 6, and 5 objects in our heaps). The two players alternate taking any number of objects from
any single one of the heaps. The goal is to ensure that the opponent is forced to take the last remaining
object.
Nim normal play the goal would be to be the last one to take an object.
Chopstick Rules
The goal of Chopsticks is to knock out the other opponent’s ”hands” by giving both hands five or
more points thus ”knocking out” or knocking apart the hands of the opponent.
Each finger is equivalent to one point. Each player starts out with two points (one finger on each
hand). A player must tap a hand in order to give it points. When a player taps an opponent’s hand,
the player adds what the opponent originally had on his/her hand and what is on the player’s hand to
get the sum. The sum is the number of fingers that the opponent now has on his/her hand. A player’s
hands do not change when the opponent’s hand is tapped. The option of being able to transfer points
from one hand to another is available. For example, if a player had three points on his or her right hand
and one on his or her left, the player could rearrange them to have two on each hand. The points must
be distributed differently after they tap their hands together; a player may not simply swap which fingers
are on which hands.
The players take turns giving each other points. Both hands of an opponent must be knocked out
(both hands receive five or more points) in order for a victory. This is called a dead hand. If a single
hand receives five or more points, the hand is eliminated (an eliminated hand is equivalent to zero points)
and the hand is useless unless it is revived by transferring points from a hand that is alive.
