he Minimax Game
Minimax is a game for two players. Five digits are presented, one at
atime, 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)
