# Acey Ducey

|
# From: BASIC Computer Games (1978)
|
|
# Edited by David Ahl
|
|
#
|
|
# "This is a simulation of the Acey Ducey card game.
|
|
# In the game, the dealer (the computer) deals two
|
|
# cards face up. You have an option to bet or not to
|
|
# bet depending on whether or not you feel the next
|
|
# card dealt will have a value between the first two.
|
|
#
|
|
# "Your initial money is set to $100. The game keeps
|
|
# going on until you lose all your money or interrupt
|
|
# the program.
|
|
#
|
|
# "The original BASIC program author was Bill Palmby
|
|
# of Prairie View, Illinois."
|
|
#
|
|
# Ruby port by Christopher Oezbek, 2021
|
|
#
|
|
# This uses the following techniques:
|
|
#
|
|
# - The programm largely consists of a GAME LOOP,
|
|
# which is used to represent one round.
|
|
# - The Kernel function rand(Range) is used to get an
|
|
# Integer in the (inclusive) Range of 2 to 14.
|
|
# - To ensure the user enters a proper Integer
|
|
# via the console, an inline 'rescue' statement is
|
|
# used.
|
|
# - To capture the long text in the introduction, a
|
|
# squiggly HEREDOC string declaration <<~ is used.
