The Minimax Game

Minimax is a game for two players. Five digits are presented, one at
a time, and used to create a three-digit and a two-digit number.
Each presented digit can be placed in any available position, but
once placed, it cannot be moved.

Before any digits are presented, an operation (addition, subtraction,
multiplication, or division) is chosen, and also a target (minimum or
maximum). The aim for each player is to create the arrangement of
three-digit and two-digit numbers, combined according to the
chosen operation, which produces the better result according to the
chosen target, minimum or maximum.

For example, if addition and minimum are the chosen operation and
target, and the five presented digits are 4, 6, 9, 2, and 5, the
arrangement below of player AAA produces a better result than the
arrangement of player BBB.

Player AAA: 629 + 45 = 674
Player BBB: 954 + 26 = 980
(the lower value is 674, so AAA wins)

Starting the Minimax Game

1. From the SELECT AN OPERATION menu, choose one of the
following:

1:ADDITION
2:SUBTRACTION
3:MULTIPLICATION
4:DIVISION

2. Then, from the SE LEC T A MODE menu choose:

1:MINIMUM NUMBER
2:MAXIMUM NUMBER

3. Next, from the INPUT PLAYER NAME screen, enter a three letter
identifier for each player.

Enter Player Names

Press } and † to cycle the display through the available letters, in
alphabetical order, and press | and ~ to move the cursor between
the positions for each letter. When three letters have been chosen,

Five spaces for digits are presented. Each player must try to place
the digits so that the final result is as high or low as possible. The
digits are presented one at a time, with those still to come unseen
until presented. The indicator mark is moved to the available
locations by pressing ~ or |. Press Í to place the digit in the
location currently indicated by the marker position. The marker only
moves to available positions.

The Box Game

Box is a game based on the relative positions of values along a
number line.

A player is presented with nine values, one at a time, each to be
placed into one of nine positions. Only one value can occupy each
position and once placed, a value cannot be moved. The position of
each value must represent its relative size, between the overall
highest and lowest values. If, when a value is presented, there is no
position available to maintain the required order, then the value is
discarded.

The game can be played by two players. Each player completes an
arrangement of the nine presented values. The player discarding
the fewest values (and hence, placing the most values) wins. In the
one-player game, the choices attributed to the second player are
made automatically by the application.

The game can be played using either integer values, decimal
values, or negative values, according to the options selected.

1. From the SELECT A BOX GAME menu choose one of the
following:

1:BOX (WHOLE NUMBERS)
2:BOXD (DECIMAL NUMBERS)
3:BOXN (NEGATIVE NUMBERS)

values to be placed. For example, in 1:BOX (WHOL E

NUMBERS)

choose either 1:0 T O 100 or 2:0 T O 1000.

3. Then from the NUMBER OF PLAYERS screen choose:

1:ONE PLAYER?
2:TWO PLAYERS?
