+# Slots
+#
+# From Basic Computer Games (1978)
+#
+#    "The slot machine or one-arm bandit is a mechanical
+#   device that will absorb coins just about as fast as
+#   you can feed it. After inserting a coin, you pull a
+#   handle that sets three indepent reels spining. If the
+#   reels stop with certain symbols appearing in the pay
+#   line, you get a certain payoff. The original slot
+#   machine, called the Liberty bell, was invented in 1895
+#   by Charles Fey in San Francisco. Fey refused to sell
+#   or lease the manufacturing rights, so H.S. Mills in
+#   Chicago built a similar, but much improved, machine
+#   called the Operators Bell. This has survived nearly
+#   unchanged to today.
+#     On the operators Bell and other standard slot
+#   machines, there are 20 symbols on each wheel but they
+#   are not distributed evenly among the objects(cherries,
+#   bar, apples, etc). Of the 8000 possible combinations,
+#   the expected payoff(to the player) is 7049 or $89.11
+#   for every $100.00 put in, one of the lowest expected
+#   payoffs of all casino games.
+#     In the program here, the payoff is considerably more
+#   liberal; indeed it appears to favor the player by 11%
+#   -- i.e., an expected payoff of $111 for each $100 bet."
+#     The program was originally written by Fred Mirabelle
+#   and Bob Harper
